+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>

+

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+Name: sox
+URL: http://sourceforge.net/projects/sox/files/sox/
+Version: 14.4.2
+SoX source code is distributed under two main licenses. The two
+licenses are in the file LICENSE.
+
+sox.c, and thus SoX-the user application, is distributed under the
+GPL, while the files that make up libsox are licensed under the less
+restrictive LGPL.
+
+Note that some of the external packages that can be linked in to libsox
+are GPLed and/or may have licensing problems, so they can be disabled
+at configure time with the relevant--with-* options. If libsox is built
+with such libraries, it must be distributed under the GPL.
+
+Description:
+SoX is a cross-platform (Windows, Linux, MacOS X, etc.) command line utility that can convert various formats of computer audio files in to other formats. It can also apply various effects to these sound files, and, as an added bonus, SoX can play and record audio files on most platforms.
+Local Modifications:
+- BUILD:
+ - Removed the examples and sox test libraries (not the sox presence tests)
+ - Renamed the sox library to sox_lib
+ - Excluded sox.c from sox_lib (because it should only be in a binary)
+ - Removed -DLADSPA_PATH from sox cc_library
+ - Rewrite includes (by googlify)
+ - Under MSAN, unpoison the output of the fistpl instruction in effects_i_dsp.c
+ - Support seeking on memory buffers (https://sourceforge.net/p/sox/patches/109/)
+ - Add a redistributable_sox_lib
+- Patches applied:
+ - sox-14.4.2-wget_check_certificates.patch: Removed --no-check-certificate
+ flag from wget invocation in formats.c, since it is a security risk.
+ - sox-14.4.2-BUILD.patch: Post googlify-build patch.
+ - sox-14.4.2-sox.c.patch: sox.c diffs.

+ o Added ability for noiseprof to use stdout and noisered to use stdin
+ [FR# 1621694]. (Reuben Thomas)
+ o vibro effect name deprecated in favour of tremolo; this effect
+ reimplemented as a special case of synth. (robs)
+
+ Other new features:
+
+ o Remove soxmix. (Reuben Thomas)
+ o Preview mode now removed, as all it did was use rate rather than
+ resample, and rate has been removed.
+ o -V now gives only user-relevant messages, use -V -V to get
+ developer-relevant messages. (robs)
+ o -V output much improved and expanded; now includes display of
+ (auto-)selected effects. (robs)
+ o sox man-page overhaul, new soxexam man-page entries. (robs)
+ o Added command line options for specifying the output file
+ comment. (robs)
+ o Added ability to merge e.g. 2 mono files to 1 stereo file
+ [FR# 1297076]. (robs)
+ o Removed the restrictions whereby multiple input files had to have
+ the same data encoding & size, and in most situations where they
+ had to have the same # of channels, and for play where they had
+ to have the same sampling-rate. (robs)
+ o Options to apply replay-gain on input; enabled by default
+ with `play'. (robs)
+ o Can now use Ctrl-C to skip to next track when playing multiple
+ files (e.g. play *.mp3); Ctrl-C twice to exit. (robs)
+ o Added --interactive option to prompt to overwrite pre-existing
+ output file. (robs)
+ o Added large file support. (Reuben Thomas)
+
+ Bug fixes:
+
+ o Fix writing MP3 files on AMD64 processors.
+ o More fixes to MP3 tag reading. Sometimes tags were
+ detected as valid MP3 frames.
+ o Fix to stop, avoiding a crash, when starting of effects fails.
+ (Reuben Thomas)
+ o Fixed a bug introduced in 12.18.2 that stopped the draining
+ of effects from occuring. This had stopped the reverse effect,
+ among others, from working. (Reuben Thomas)
+ o Several effects are now optimised out in situations where they need
+ do nothing, e.g. changing rate from 8000 to 8000, or changing volume
+ by 0dB [Bug# 1395781]. (robs)
+ o Fix rounding error when reading command-line time
+ parameters. (robs)
+ o Fix nul file hander ignoring other format options if rate
+ option has not been given. (robs)
+ o Fix synth length accuracy. (robs)
+ o Fix broken audio when downmixing with any of the following
+ effects: synth, deemph, vibro. (robs)

+ & FLAC. (robs)
+ o Fix wav file handler discarding the last PCM sample in certain
+ circumstances. (robs)
+ o Fix [1627972] AIFF read bug when MARK chunk present. (Richard Fuller)
+ o Fix [1160154] VOX to WAV conversion problem. (robs)
+ o Removed (for output file only) the potentially
+ problematic -v option. Use the vol effect instead. (robs)
+ o Improved the accuracy of integer and floating point PCM
+ conversions. (robs)
+ o Don't go into a loop on zero-padded WAVs. (Jorge Serna)
+ o Fix to AIFF writing to avoid writing invalid files in some situations.
+ (Reuben Thomas)
+ o Fix compander effect bugs: [1613030] Compand fails to compress
+ clipping, [1181423] compand with 0 sec attack/release. (robs)
+
+ Internal improvements:
+
+ o More and better self-tests. (robs)
+ o Build system overhaul to use the full set of GNU autotools.
+ (Reuben Thomas)
+ o Add new getopt1.c to win32 project file.
+ o Remove old, optional rate change and alaw/ulaw conversion code.
+ (Reuben Thomas)
+ o Removed the old internally invoked (but mentioned in the man page)
+ copy effect. (robs)
+
+
+sox-12.18.2 2006-09-03
+-----------
+
+ o Adding in Debian's disk full fix (#313206).
+ o Finally got rid of reference to cleanup() function in
+ library. Applications are now required to detect
+ all failures from return codes and cleanup as they
+ want.
+ o Changed how list of formats and effects are stored internally.
+ Effects libst users only. Dirk
+ o Store effects usage so that its accessable by applications.
+ Dirk
+ o Modify the synth effect to not use SIGINT to stop processing
+ and instead return ST_EOF. This allows exact acount of
+ samples to be written out instead of an approximate amount.
+ o Fix hangup when attempting to write stereo MP3 files.
+ (1512218) Kendrick Shaw
+ o Fix deemph effect would lose stereo separation. (1479249) robs
+ o Adding cross-platform support for getopt_long
+ o Make help screens print much more information and add
+ new --help-effect option. (Originally from Dirk).
+ o Add support for using an external gsm library instead of
+ just the internal one. Vladimir Nadvornik
+ o Updates to nul file handler to prevent crashes during output.
+ Martin Panter (1482869)
+
+
+sox-12.18.1 2006-05-07
+------------
+
+ o The "filter" effect could go into infinite drain mode. Now
+ only drain 1 buffer. noisered as well.
+ o SoX was ignoring user aborts (ctrl-c) if it occured during
+ effect drain operations. This was bad if effects had
+ bugs and stuck in infinite loop.
+ o Stop SoX from crashing when file type could not be auto
+ determined (1417776).
+ o Output filenames with multiple '.' confused SoX. (1417776)
+ Christian Hammer
+ o Moved to a common set of CLIP routines. This fixed clipping
+ bugs in noisered and mcompand.
+ o Stop SoX from crashing on sphere files that contain large text
+ strings. (1430025) Ulf Hamhammar
+ o Fix some overflow crashes in aiff handler. (1430024) Ulf Hamhammar.
+ o Under windows, set piped input/output to binary mode (1417794). Martin
+ Panter
+ o Fixed broken internal version of strdup(). (1417790) Marty
+ o Stop infinite loop when reading MP3's with a tag size of
+ exactly 8192 bytes. (1417511) Hans Fugal
+ o Fix typo in stlib.dsp for loading in Visual Studio 6.
+ o Fixed problems in silence effect related to removing multiple
+ periods of silence from the middle of the sound file.
+ o Reduced the window size greatly on the silence effect to
+ prevent leaving in silence that looked like noise still based
+ on RMS values.
+ o Prevent infinite loop in pitch effect from uninitialize variable.
+ Frank Heckenbach
+ o Prevent crashes when printing error mesages (1447239)
+ o Added makefile and support files to compile using Open Watcom
+ compiler. (1417798) Marty
+ o Stop calling flow() on effects that returned EOF during drain(). Allows
+ two back-to-back reverse effects to work.
+ o Added support for multiple channels in .dat files.
+ (1366634) tomchristie
+
+
+sox-12.17.9 2005-12-05
+-----------
+
+ o Updates to compile under VC6. Jimen Ching
+ o Declare st_signalinfo_t to specifically be signed in case
+ platform does not default ot signed chars. This
+ is required for NetBSD/powerpc.
+ o When seek()ing in AIFF, SMP, and WAV handlers, remaining samples were
+ incorrectly computed based on bytes and not samples. Jukka
+ o Changed noisered effect to just warn during clipping instead
+ of aborting. Ian Turner
+ o Fixed bug were pieces of audio were lost every buffer read
+ when running both -c and -r options together on mono audio.
+ Users probably percieved it as shorter audio files that
+ played with a sped up tempo.
+ Bugfix will also apply to other times when multiple effects
+ are ran on the command line.
+ o Added support for -V option to play/rec scripts.
+ o Fix to silence effect to allow negative periods to be specified
+ (to remove silence from middle of sound file).
+ o Fix swap option handling so that special case of "swap 1 1" will
+ work.
+ o Track length of Ogg Vorbis files on read.
+ o Add support for displaying a status line that tracks progress
+ of read/write routines. Part of information requires read
+ file handlers to be able to determine file length.
+ o Converted alsa driver to use asoundlib instead of directly
+ talking to kernel driver. This also means that device names
+ are now the ALSA logical names instead of /dev type names.
+ o Added ALSA support to play/rec scripts.
+ o Added st_open*, st_read, st_write, st_seek, st_close routines
+ to help simplify developer interface to libst. See libst.3..
+ o Removed st_initformat(), st_copyformat(), and
+ st_checkformat() from library. If your app used those
+ functions then copy them from 12.17.8 source code
+ directly into your application or update to use new
+ routines.
+ o Force word-alignment on AIFF SSND and APPL chunks on input.
+ Matthew Hodgson.
+ o Add fix to WAV handler to only return data in multiples
+ of sample_size*channels to better handle corrupt files.
+ o Fixed bug where "-4" option didn't work with avg
+ effect (Tom Christie).
+ o Fixed fade's fade-out-length to match man page
+ description as noted by Geoff Kuenning. This required
+ updates to the sample crossfade scripts. Also modified fade
+ effect to report when no more samples will be produced to
+ prevent unneeded reading of whole file.
+ o Allow aborting SoX with SIGTERM, along with previous SIGINT.
+ Norman Ramsey.
+
+
+sox-12.17.8 2005-08-22
+-----------
+
+ o noisered effect had compile problems with some compilers.
+ o "-x" option was being ignored since 12.17.7.
+ o Stuart Brady added support for reading and writing RIFX files (big
+ endian RIFF/WAV files). Also added support for auto detecting
+ DEC-style ".sd\0" files.
+ o Gene Mar found typo in polyphase nuttall calculation.
+ o SMP buffer overflow (detected by gcc 4.0). Reported by Marcus Meissner
+ and Matthias Saou.
+ o Fixed URL in manpage to resample overviews.
+ o Fixed WAV handler so that it didn't think WAV chunks with max size
+ were invalid chunks. This allows WAV's to be used in pipes since
+ they have to default to max size.
+ o WAV files with alaw or ulaw data don't need extended format chunks.
+ (Lars Immisch)
+ o In AIFF files, fixed problem were short comments should cause
+ AIFF handler to get confused and become misaligned.
+
+
+sox-12.17.7 2004-12-20
+-----------
+
+ o Christian Weisgerber sent patches to man page fixes
+ and patches for sunaudio driver on openbsd.
+ o Default volume for soxmix wrongly set to 0 instead
+ of 1/#_input_files (float rounding error).
+ o Update to ALSA driver to do a better job of detecting
+ unsupported sample rate/size/encoding and change to
+ a supported one.
+ o Fix bug in alsa writing were last last partial buffer
+ wasn't being flushed.
+ o Guentcho Skordev pointed out ogg vorbis files were using
+ the same value for serial numbers each time.
+ o Changed sox to only read the exact size of a WAV data chunk
+ if cooledit IFF LIST chunk is found at the end of the file.
+ Normally, this isn't done to allow reading > 2gig WAV files.
+ o Modified configure to detect cygwin compiler after detecting
+ gcc compiler (fixes some default CFLAGS options).
+ o Added explicit rule for compile *.o from *.c so that
+ CPPFLAGS is always referenced. Not all platform's default
+ rule includes CPPFLAGS (FreeBSD).
+ o Under linux, add include path to /lib/modules/* so that ALSA
+ include files can be auto detected.
+ o Ian Turner added an effect to remove noise from an audio
+ file by first profiling silent periods of the audio
+ to determine what the noise is (like background hiss on
+ cassette tapes).
+
+
+sox-12.17.6 2004-10-13
+-----------
+
+ o Changed comment code to always use copies of strings to
+ fix bug in WAV handlering freeing argv[] memory.
+ o Use calloc() to create ft_t structures so that all
+ memory is initialized before being referenced.
+ o Fixed VOC EOF bug were it thought there was an extra
+ block when there wasn't.
+ o Restructured directory layout so that source code is in
+ a seperate directory.
+ o Modified SoX to accept multiple input files. Concatenates
+ files together in this case.
+ o Removed map effect so that loops and instr could be removed
+ from effects structures. This makes effects engine stand
+ alone from the rest of the sox package.
+ o Benedikt Zeyen found a bug in synth effect when generating
+ brown noise that could cause clipping.
+ o David Leverton sent another patch to prevent crashes on
+ amd64's when resampling.
+ o Fixed a bug were MP3 files with large ID3v2 tags could
+ cause SoX to stick in a loop forever. Now, it will
+ abort on IDv3 tags larger then 100k. Could still be
+ improved to handle any size.
+ o Changed volume option (-v) so that it tracks the file
+ it was specified. This means that when specified with
+ the input file, it changes volume before effects engine
+ and when specified with output file, its done after effects
+ engine.
+ o Added crossfade_cat.sh script that will concatenate to
+ audio files and do a crossfade between them.
+ o Fixed bug in fade effect were it was impossible to do a
+ fadeout starting from the beginning of the audio file.
+ o Removed rounding error when changing volume of audio with
+ "-v" option. This error caused doing a "-v -1.0" twice
+ to not result in the original file.
+ o Fixed a possible overflow in lots of effects were MIN
+ value was treated as -MAX instead of -MAX-1.
+ o Modifed sox so its OK for effects to not process any
+ input or output bytes as long as they return ST_EOF.
+ o When effects output data and reported ST_EOF at the
+ same time, that buffer was discarded as well as
+ data from any chained effect.
+ o Added patch from Eric Benson that attempts to do a seek()
+ if the first effect is trim. This greatly speeds up
+ processing large files.
+ o Daniel Pouzzner implemented a multi-band compander (using
+ the butterworth filters to split the audio into bands).
+ o Donnie Smith updated the silence effect so that its possible
+ to remove silence from the middle of a sound file by
+ using a negative value for stop_periods.
+ o Changed float routines to only work with normalized values
+ from -1:1.
+ o Modifed .au handler to be able to read and write 32-bit
+ and 64-bit float data. Only tested reading so far.
+ o WAV with GSM data now always pads data to even number of bytes.
+ o Added support for writing 32-bit audio to AIFF.
+
+
+sox-12.17.5 2004-08-15
+-----------
+
+ o Thomas Klausner sent in patches to compile audio drivers under
+ NetBSD.
+ o Rahul Powar pointed out a memory leak in the WAV file handler.
+ It wasn't calling the correct close() function when closing
+ input files.
+ o Modified play.1 man page to not use multiple name lines. This
+ appears to confuse some conversion programs. Updated sox.1
+ man page for typo in reverb option.
+ o Andrew Church fixed problem with header of stereo 8SVX files.
+ o Jimen Ching added support to scan over garbage data at the
+ beginning of MP3 files to find valid frames. This is useful
+ to play WAV and AIFF files that have MP3 data in them until
+ those handlers support it directly. To play those, force
+ sox to use the mp3 handler with the "-t mp3" option.
+ o Added patch from Ulf Harnhammar to wav handler to prevent
+ buffer overflows.
+ o Added patch from Redhat to allow resample to work on certain 64-bit
+ machines (Sam Varshavchik)
+ o Tony Seebregts added a file handler for headerless Dialogic/OKI ADPCM
+ files (VOX files).
+ o Jan Paul Schmidt added a repeat effect to do loops the brute force way.
+ This is also good for file format that don't support loops as well.
+ o Fix for OSS driver in rate tolerance calcs that were off because
+ of type conversion problems. Guenter Geiger.
+ o Allow reading sphere files with headers greater then 256 bytes. Jimen
+ Ching.
+ o Fix for vorbis were comments are displayed in KEY=value format always.
+ Stop printing some info to stdout in case output is a pipe. Guenter
+ Geiger.
+ o J Robert Ray submitted fix for AIFF handler to ignore lowercase
+ chunks that are unknown.
+ o Bugfix for 8-bit voc files. Jimen Ching
+ o General warning cleanups (cbagwell)
+ o Memory leaks in reading WAV files (Ufuk Kayserilioglu)
+ o Rearrange link order of ogg vorbis libraries so that they
+ can be compiled as static. (Christian Weisgerbr)
+
+
+sox-12.17.4 2003-03-22
+-----------
+
+ o Peter Nyhlen fixed a problem with reading Comments in Ogg Vorbis files.
+ o Added install target to allow installing libgsm from main Makefile.
+ Leigh Smith.
+ o Minor updates to sox.c to free unused memory and close all input
+ files during failures.
+ o Pieter Krul added a patch that makes play script look at AUDIODEV
+ environment variable if it exists to find which device to use.
+ This allows scripts to work with Solaris SunRays and is a good idea
+ in general.
+ o Updated config.sub to detect latest supported OS's.
+ o Fabrizio Gennari added support for reading and writing
+ MP3 files using the external libraries libmad and libmp3lame.
+ o Jens Henrik Goebbert sent in several bugfixes for integer overflows
+ in the compand effect.
+ o Dan Dickerman sent in patches for integer overflows in the resample
+ effect.
+ o Jimen Ching sent in a fix for multi-channel sound file processing
+ using the avg effect.
+ o Richards Bannister added patches to clean up prototypes and filter
+ private sizes being to small.
+ o Jimen Ching adds -d option to specify 64bit data size and changed
+ Ulaw/Alaw encoding to default to 8bit data size if not specified.
+ o David Singer pointed out that a MS program creates AIFF files
+ with an invalid length of 0 in its header. Changed SoX to warn the
+ user but continue instead of aborting since SoX can still read
+ the file just fine.
+ o Bert van Leeuwen added a file handler for Psion record.app used
+ for System/Alarms in some Psion devices.
+ o Richard Bannister sent in a patch to make writing vorbis files
+ work with Vorbis 1.0 libraries.
+ o Fixed configure scripts so that they can be ran with the
+ --with-oss-dsp, --with-alsa, and --with-sun-audio options.
+ Was causing compile time problems. Reported by Raul Coronado.
+ o Change Ogg Vorbis support to use VBR encoding to match defaults
+ of oggenc based on suggestion from Christian Weisgerber.
+ o Prints error message now when a channel value of -1 is given.
+ Reported by Pierre Fortin.
+ o Fixed bug were memory could be trashed if a input WAV file contained
+ a comment. Found by Rhys Chard.
+ o Change command line to compile soxmix.o slightly to try and make
+ Forte compiler happy.
+ o Added support for ALSA 0.9 driver. Jimen Ching
+
+
+sox-12.17.3 2001-12-15
+-----------
+
+ o Removed check that prevented pan from being invoked when the
+ input and output channels were the same.
+ o Ciaran Anscomb added a flush to sunaudio driver after changing
+ settings. This is because it can start buffering data as soon
+ as the device is open and the buffered data can be in a
+ wrong format.
+ o trim wasn't accounting for # of channels and was generally broken.
+ o Jeff Bonggren fixed trim bugs were it was failing when triming
+ data that equaled to BUFSIZ. Also, trim now immediately returns
+ ST_EOF when its done instead of requiring an extra call that
+ returns no data.
+ o auto effect wasn't rewinding the file if the file was less then
+ 132 bytes. Changed auto parsing of header to be incremental
+ instead of reading in a large buffer.
+ o William Plant pointed out a bad pointer access in fade effect's
+ parsing of options.
+ o Ken pointed out a problem were private data was not 8-byte aligned
+ and causing crashes on most RISC CPU's. Fixed by going back to
+ old style of declaring private data as type "double" which usually
+ forces strictest alignment.
+ o ima_rw was miscompiling on alpha's because of a header ordering
+ problem.
+ o Erik de Castro Lopo pointed out that when writing 16-bit VOC files
+ the headers did not contain the correct length or encoding type.
+ o Seperated st.h into 2 files. st.h for libst users and st_i.h for
+ internal use.
+ o Added new types used extensively by libst: st_sample_t & st_size_t.
+ This allows for more deterministic behavior on 64-bit machines and
+ also allows sox to possibly work with much larger file sizes.
+ o SoX was some times getting confused and thinking an EOF was an
+ error case when reading audio files. Removed unneeded aborts
+ when EOF was OK.
+ o Silence effect was broken on stereo files. Also, made thresholds
+ relative to original bit percision of audio data. When 16-bit audio
+ is scaled up to 32-bits, a little bit of noise starts to look like a
+ large amplitude of noise. Also, now using RMS values to smooth out
+ clicks. RMS rolling window size is 1/10 of sample rate.
+ o Changed Floats into a type of encoding instead of a size of audio data.
+ o Put a flush at the end of OSS driver so that no old data would be
+ left in internal buffers after changing audio format parameters.
+ o Fixed problem where play script wasn't installed correctly if you
+ build from another directory (pointed out by Mike Castle).
+ o Made GSM support internal to libst (no external library required).
+ o Change configure script to enable ulaw/alaw lookup tables and GSM
+ support by default. Also have Makefile's make use of more configure
+ prefix options to allow for customized installs.
+ o Reverted ulaw/alaw conversion routines back to Sun's versions.
+ o Modified raw file handler to write files in the same generic buffered
+ fashion that was added for reading in 12.17.2. Seems to have
+ speed up some types of writing.
+ o Reading Ogg Vorbis files could get confused of when EOF was reached.
+ o Added uninstall rules to Makefile. Added new ststdint.h to define
+ *int*_t typedefs.
+ o Added internal strcasecmp for OS/2.
+ o Added support for swapping "bit" order (MSB becomes LSB) for raw u-law
+ and A-law data. Some ISDN equipment prefers it this way. Use -x flag
+ or new .la or .lu file extensions.
+ o Annonymous patch submitted to fix types and spelling problems in
+ various files. Also, updated VOC files to have u-law and A-law
+ support as well as able to read in VOC files using a pipe. More
+ examples added to soxexam file.
+
+
+sox-12.17.2 2001-09-15
+-----------
+
+ o Daniel Culbert found and fixed a bug in the polyphase effect
+ that occurs on platforms that rand() can return large values.
+ The bug resulted in polyphase resampling an audio file to a
+ different rate then it said it was.
+ o Stan Seibert contributed a handler for Ogg Vorbis files. It
+ handles all input formats but can only save using default
+ settings.
+ o Darrick Servis has made major cleanups in the code in regards
+ to error conditions. Helps people using libst.
+ o Darrick Servis has added added optional seek functionality sox.
+ Several formats have been modified to make use of this.
+ o Geoff Kuenning rewrote the average effect into a general-purpose
+ parametric mapping from N channels to M channels.
+ o Geoff Kuenning added an optional delay-time parameter to the compander
+ effect to allow companding to effectively operate based on future
+ knowledge.
+ o Geoff Kuenning Added support to fade and trim effect for specifying time
+ in hh:mm:ss.frac format.
+ Fixed a bug that caused integer overflow when large start/stop times
+ were used.
+ o Geoff Kuenning updated play/rec/soxeffect scripts to handle all effects
+ added since 12.17. Spell-checked soxexam.1 file.
+ o Jimen Ching updated ALSA configure support to auto-detect 4.x or 5.x API
+ and compile correctly under those two. All other versions are unsupported.
+ o Merged in the NetBSD package changes into CVS finally.
+ o Removed broken support for non-ANSI compilers.
+ o Makefile now places the correct path to SoX in the play/rec scripts
+ based on configuration script values.
+ o Alexander Pevzner provided a fix for OSS driver for sound being
+ dropped under heavy CPU loads. Moved GETBLKSIZE operation
+ until after setting up the format (SBLive! was modify the block size
+ after changing formats).
+ o With help from David Blythe, updated OSS drivers to use newer format
+ interface. OSS driver will now attempt to detect a valid endian type
+ to use with sound card.
+ o Carsten Borchardt pointed out a bug in lowp filter. Added new
+ nul file handler that reads and writes from/to nothing.
+ Also added new synth effect that creates sounds using a simple
+ synthesizer. Created a testcd.sh that uses two new features
+ to create a test sound CD for testing audio equipment.
+ o Ben Last added a new program that uses libst and will merge two
+ seperate audio files into a single file with multiple channels.
+ This was merged into the standard sox.c file by cbagwell.
+ o Andreas Menke fixed some problems with the speed effect and
+ how effects were drained. Also improved the usage of printf()'s
+ to use stderr.
+ o Corrected AU header length value when comments were less than
+ 4 bytes.
+ o Added support for reading non-standard bit size data from AIFF files.
+ o Ignore unmatched MARK/INSTR chunks in AIFF files now instead of quiting.
+ o Fixed ALAW encoding bug in .au files as pointed out by Bruce Forsberg.
+ o Unified the raw reading functions. Probably slightly faster for
+ most datatypes but was done to fix recording from the OSS driver.
+ Control-C stopped working somewhere during the 12.17 series.
+ o Ford Prefect added a dcshift which can shift the midline amplitude
+ towards the true center. This will allow for a greater range
+ of volume adjustments without clipping audio data.
+ o Heikki Leinonen submitted a silence effect that will trim off
+ silence from the beginning of a file. cbagwell made some modifications
+ to trim off front and back as well as some other tweaks.
+ o Made the "auto" effect the default file handler for input files.
+ Also have auto handler now use file extensions if it can't figure
+ it out.
+
+
+sox-12.17.1 2000-11-19
+-----------
+
+ o Andreas Kies fixed a bug were we were not detecting correctly
+ if an output file was seekable.
+ o Fixed a bug in the mask effect introduced in 12.17. If the libc
+ version of rand() returned more then 15-bit values then it would
+ trash your data. Reported by Friedhel Mehnert.
+ o Added a new fade in/out effect from Ari Moisio.
+ o AIFF files now ignore a MARK chunk if the loop type is NoLoop (0).
+ o Fixed bug were it was impossible to output ADPCM data in wav files.
+ o Fixed bug were rate had to be specified for sphere files (fix from
+ Antti Honkela).
+ o Added small work around to let compile with cygwin's gcc 95.2
+ which also now allows to compile with GSM support under windows.
+ o Removed accessing of sound devices in tests for sound support and
+ instead just look for needed header files. This allows the sound
+ support to be detected even if the device is currently busy or when
+ compiled on a box that doesn't have a sound card but the OS supports
+ it (which is the enviornment of most distributions creating new
+ binaries).
+ o Added support to partially handle AIFC files but only uncompressed
+ versions. This should allow people to work with raw CD audio data
+ on Mac OSX and also gives a basis for adding future support for
+ things like ADPCM processing.
+ o Added new "earwax" effect from Edward Beingessner. It is meant to
+ be used for CD audio played through headphones. It will move the
+ sound stage from left/right to in front of you.
+ o Trim effect did not compute locations as was documented in the
+ man pages. Changed effect so that it computed the time the
+ same way that the fade effect does.
+
+
+sox-12.17 2000-09-08
+---------
+
+ o Sox can now read and write w98 compatible gsm .wav files,
+ if compiled properly with libgsm. Thanks go to Stuart
+ Daines <sjd.u-net.com> for the gsm-wav patches.
+ This is new, and relatively untested. See -g format option.
+ o Sox can now write IMA_ADPCM and ADPCM compressed .wav,
+ this is new, and relatively untested. See -i and -a format
+ options in manpage.
+ o General changes to wav.c for writing additional wav formats.
+ Reading wave headers: more consistency checks.
+ Writing wave headers: fixes for w98.
+ o Speedups to adpcm read routines, new codex versions are
+ now in ima_rw.c and adpcm.c.
+ o Speedups for raw.c, especially for gcc with glibc.
+ o Fixed a segfault problem with ulaw/alaw conversion, where
+ an out-of-range index into the tables could occur.
+ o More detailed output from the stat effect.
+ o Continued rewrite of resample.c, now it is almost as
+ fast with floating arithmetic as the old (buggy) version
+ was with 16-bit integer arithmetic. The older version
+ in sox-12.16 shifted frequencies slightly and was less
+ accurate. (Stan Brooks)
+ o Extensive rewrite of polyphas.c, should be faster and use less memory
+ now. The sox-12.16 polyphase code had some bugs. (Stan Brooks)
+ o New effect 'filter' which is a high-quality DSP lowpass/
+ highpass/bandpass filter using windowed sinc function
+ methods, like polyphase and resample. (Stan Brooks)
+ o Jan Paul Schmidt added new low/high/bandpass and bandlimit
+ filters to sox. They have much better results then the old
+ versions of low/high/bandpass. The new effects are all
+ Butterworth filters.
+ o New data file type supported, -sl or extension .sl for
+ signed 32-bit integers. Some simplification of the raw.c
+ source.
+ o Some test programs and scripts in the test directory, for
+ making gnuplot plots of frequency response, error-levels
+ of rate-conversion and filter effects.
+ o Removed sbdsp code. All modern unixes are support via OSS,
+ ALSA, or sun audio device interfaces.
+ o Added AVR handler from Jan Paul Schmidt.
+ o SoX now waits until the last possible moment before opening
+ the output file. This will allow all input and effect options
+ to be parsed for errors and abort before overwriting any file.
+ o SoX will no longer write to files that exists. This will keep
+ it from deleting files when a user mistakenly types "sox *.wav".
+ o Added new compander effect from Nick Bailey. Nice general purpose
+ filter.
+ o Under Solaris, SoX now checks hardware ability to play stereo/PCM
+ and forces output data to match. Sorry, no SunOS support. I don't
+ have access to one any more.
+ o Fixed array overrun bug in rate effect as pointed out by Ian
+ Donaldson.
+ o Fixed clip24() range as pointed out by Ted Powell.
+ o Fixed possible segfault in echos effect, as pointed out by Zinx
+ Verituse.
+ o Moved most documentation to new "soxexam.1" manual page so that
+ all users on a unix system will have access to important information.
+ This means no more TIPS, CHEATS, or CHEATS.eft files.
+ o Richard Kent fixed a byte alignment problem in aiff comment code.
+ o Loring Holden added support to create missing directories on install
+ and support for installs from outside the source directory.
+ o Fabien COELHO added a pan and volume effect.
+ o Fabien COELHO added a speed effect to sox (like speeding up a tape
+ machine). Also added pitch which changes pitch without effecting
+ duration and stretch which stretch time without effecting pitch.
+ o Leigh Smith updated aiff support to use the COMT check when writing
+ comments instead of the ANNO. It is the prefered method from Apple
+ and newer programs are starting to require it. Also fixed some bugs
+ in how we compute the length of various chunks in output files.
+ o Changed the default block alignement for IMA ADPCM WAV files to use
+ 256 which is what windows programs use. Badly written readers expect
+ 256.
+ o Matthias Nutt helped add support for specifying multiple effects
+ to SoX on the command line.
+ o Curt Zirzow added a trim effect to trim off audio data.
+ o Updated ALSA driver to support new interface. Jimen Ching
+
+
+sox-12.16 1999-07-13
+---------
+
+ o Changed raw data functions to perform I/O operations using block reads.
+ Should improve speeds greatly, especially when filesize is in megs.
+ Got code ready to tweak speed more which also forced me to clean up
+ Endian test code.
+ o Fixed a bug in .au's handling of G.723. It wasn't using the correct
+ number of bits. Added A-law support to .au.
+ o Quoted $filename in play/rec scripts so that files with spaces in
+ their names can be given.
+ o Old OS/2 support didn't work. Replaced with known working EMX
+ GCC compatible code.
+ o ADPCM WAV files were defaulting to 8-bit outputs and thus losing
+ some persision. Now defaults to 16-bit signed uncompressed data.
+ o Fixed a couple cross-platform compiler issues.
+ o Jimen Ching has added support for "configure" in to SOX. Finally,
+ a good solution to cross-platform compiling!
+ o Jimen Ching has added native support for the ALSA driver to play
+ and record audio from. (jching@flex.com)
+ o Minor correction for -r example in manual page.
+ o Renamed sox.sh to soxeffect and rewrote. Symbolic links can be made
+ from this file to the name of a sox effect. It will then run that
+ effect on STDIN and output the results to STDOUT.
+ o Fixed up some makefiles and 16-bit support from patches sent by
+ Mark Morgan Lloyd (markMLl.in@telemetry.co.uk). Also added some
+ nice DOS test bat files from him as well.
+ o Cleaned up some more cross-platform compile problems. In the process
+ got it working with Turbo C again, kinda. It still locks DOS up at times.
+ o Made AIFF handler work with invalid headers that some programs generate.
+ Also fix an Endian bug thats been there for quite a long time (when
+ ran on Intel machines). Made comment lengths even length to make
+ most MacOS programs happy. cbagwell
+ o Resample function was updated by Andreas Wilde
+ (andreas@eakaw2.et.tu-dresden.de) to fix problem were freqs. were
+ off by a factor of 2.
+ o Added an effect that swaps stereo channels. cbagwell
+ o Combined play and rec scripts to a single program to ease mantaince.
+ Also added GNU style long-options (--help). Careful, some options have
+ change (but more logical).
+ o Fixed a very old silly bug were low/high/bandpass filters would
+ add some trash data to the end of the sound file.
+ o "avg" effect wouldn't give error message when you tried to average
+ x number of channels in to the same number of channels.
+ o Fixed core dump when writting AIFF files with no comments.
+ (Olaf Pueschel)
+
+
+sox-12.15 1998-10-01
+---------
+
+ o Juergen Mueller moved Sox forward quite a bit by adding all the
+ most commonly known "Guitar Effects". He enhanced echo support,
+ added chorus, flanger, and reverb effects. He also wrote a very
+ handy CHEAT.eft file for using various effects.
+ o Incorporated Yamaha TX-16W sampler file support provided by
+ Rob Talley (rob@aii.com) and Mark Lakata (lakata@physics.berkeley.edu).
+ o Fixed a small bug in hcom compression, dependent on sign
+ extension. Leigh Smith (leigh@psychokiller.dialix.oz.au).
+ o sox -h now prints out the file formats and effects supported.
+ Leigh Smith and Chris Bagwell.
+ o smp transfers comments more completely. Leigh Smith.
+ o aiff manages markers and loops correctly and produces more
+ verbose output. Leigh Smith.
+ o Added polyphase resampler (kb@ece.cmu.edu). This adds a slightly
+ different resampling algorithm to the mix.
+ o Michael Brown (mjb@pootle.demon.co.uk) sent a patch to stop crashes
+ from happening when reading mono MS ADPCM files.
+ o Fabrice Bellard has added a less buggy 'rate' conversion. I've left
+ the old rate code included but if all goes well this will become
+ the new 'rate'. Please test and let me know how it works. Resample
+ effect needs to be reworked now.
+ o Heiko Eissfeldt: Implemented a simple deemphasis effect for
+ certain audio cd samples.
+ o Matija Nalis (mnalis@public.srce.hr) sent a patch to fix volume adjustment
+ (-v) option of sox.
+ o Fixed typo in optimazation flag in unix makefile, as pointed out by
+ Manoj Kasichainula (manojk@io.com).
+ o Fixed missing ';;' in play script. cbagwell
+ o Fixed bug in determining length of IMA and MS ADPCM WAVE files. cbagwell
+ o Fixed bug in how stereo effects were drained which fixed the
+ "reverse" effect from only saving half of stereo files. cbagwell
+ o Can use "-e" without an effect again.
+ o Added -g and -a options for new style support of GSM and ADPCM. Added
+ error checking to various formats to avoid allowing these types.
+
+
+sox-12.14 1998-05-15
+---------
+
+ o Bumped major version number up and shortened name. The shorter name
+ should help the various distributions using this package.
+ o Added support for MS ADPCM and IMA (or DVI) ADPCM for .wav files.
+ Thanks to Mark Podlipec's xanim for this code (podlipec@ici.net).
+ o Change Lance Norskog's email address to thinman@meer.net. The old
+ one was bouncing.
+ o Added path string to play and rec strings so that it could be run by
+ users without complete paths setup (i.e. Ran by "rc" files during bootup
+ or shutdown)
+ o Fixed -e option from Richard Guenther
+ (richard.guenther@student.uni-tuebingen.de) and fixed a small bug
+ in stat.
+ o Fixed a bug in the mask effect for ULAW/ALAW files.
+ o Fixed a bug in cdr output files that appended trash to end of file.
+ o Guenter Geiger (geiger@iem.mhsg.ac.at) made a rather large patch to
+ allow sox to work on 64-bit alphas. It was done the easiest meathod
+ by changing all long declarations to use a macro that knows to
+ make it 32-bits. Want to port to another 64-bit-but-not-alpha
+ machine? Grep for "alpha" to see changes. There are most likely
+ several bugs left for alphas. Guenter is also supporting this
+ package for the Debian distribution.
+ o Did some major code cleanups to clear out some warning messages
+ during compile. This is to clear up problems I'm finding under
+ both alpha and dos. Some warning messages are actually useful
+ now (pointing out possible data loss). Hopefully, I didn't
+ break anything.
+ o Code clean up allows me to finally compile code under Turbo C
+ again. Too bad the EXE gets a currupted stack somewhere and locks
+ up the system. Anyone want to try it with Borland C for me?
+ If you get a working EXE I would like to start distributing a DOS
+ package like there used to be.
+ o Speaking of cleanups, anyone want to help cleanup the makefiles for
+ various platforms? They are quite outdated right now and it is
+ very obvious that Sox hasn't been able to compile under all the
+ platforms it once did for several releases. Please send in
+ the cleaned-up makefile versions along with what programs you
+ used to compile it with.
+ o There is a known bug in hcom's compress() function. It is allocating
+ memory that can't be free'd under some OS's. It causes a core dump.
+
+
+sox-11gamma-cb3 1997-03-28
+---------------
+
+This release of sox is mainly a bugfix release. The following things
+have changed:
+
+ o Documentation has been updated when it was obviously wrong.
+ Much more work could be done. Man pages were updated to
+ work correctly on Solaris and add some missing info.
+ o Several people sent me patches to fix compiling on Solaris
+ as well as fix a few bugs.
+ o Change USS driver's name to OSS. Man, does that driver
+ like to change names! This could cause problems if you
+ have made your own custom play and rec scripts.
+ o Updated my email address. Sorry if I haven't responded to
+ any emails as I no longer have access to my old address.
+ Please use cbagwell@sprynet.com.
+ o Fixed unix test scripts so that they worked again.
+ o Fixed endian bug in psion .wve code.
+ o Replaced outdated voc info file with detailed format info
+ inside voc code.
+ o Added new sound format, cvsd (Continuously Variable Slope Delta)
+ from Thomas Sailer (sailer@ife.ee.ethz.ch).
+
+
+sox-11gamma-cb2 1996-10-04
+---------------
+
+This release of sox is based on the latest gamma version released
+plus some patches I've made to support the following new features:
+
+I would like to thank everyone that wrote me about the long
+standing bug in Sox that could DELETE your /dev/* file if the
+program was aborted for reason such as invalid audio file. Special
+thanks for Bryan Franklin for sending in a patch when I was
+to busy to even look for it.
+
+ o Better play support for 8-bit stereo voc files. New support
+ for outputing both 8-bit and 16-bit stereo voc files.
+ o Built-in support for playing and recording from Linux /dev/dsp.
+ This is a re-write and seperate module from the previous
+ support included inside the sbdsp module. Also fixes a buffer
+ size bug that showed up when using newer versions of OSS.
+ This driver will work with OSS (and older versions called USS, TASD
+ and Voxware).
+ o Support for audio playing and recording with SunOS /dev/audio.
+ o Fixes a bug were /dev/audio or /dev/dsp could be deleted
+ when playing an invalid format audio file.
+ o Expanded options for play and rec scripts. You can now specify
+ sox effects after the filename and hear them in real time.
+ Please be sure that an older version of sox is not in your path
+ because these script will possibly find it first and
+ incorrectly use it.
+ o Setting play/record volume still requires an external program.
+ If you have one a command line program to do this (such as
+ "mixer" for Linux) then you will want to edit the play and rec
+ to use this. The current support for it is only in example
+ form of how it can be done.

+ SoX Installation
+ ----------------
+
+SoX should compile and run on any POSIX compatible system (Linux, BSD,
+Solaris, Xcode on Mac OS X, Cygwin on MS-Windows, etc.). Some
+non-POSIX compilers (such as MSVC) are supported via the `CMake' build
+utility. For other compilers/systems, it is often possible to
+manually construct a custom `soxconfig.h' and `Makefile' for that
+system (the minimum requirements are 32-bit CPU, 64-bit FPU, C89
+compiler).
+
+Note that the `play', `rec', and `soxi' programs are in fact just
+copies-of or links-to (depending on OS) `sox'.
+
+SoX optionally makes use of some external libraries to obtain support
+for additional file formats and/or effects. Optional libraries should
+be installed before compiling SoX. The current list of supported
+libraries, where to get them (if not from your OS distribution), and
+their licence types, is as follows:

+
+
+
+Compiling and installing on a POSIX system
+------------------------------------------
+
+First install any optional libraries that you need for SoX. Some
+libraries may require pkg-config to be installed to be properly
+detected by SoX.
+
+[Only if you're compiling the git sources, first make sure you have
+the GNU autotools installed (automake >= 1.9, autoconf >= 2.62) and
+run
+
+ autoreconf -i
+]
+
+To compile and install SoX (executables, libraries, manual pages) with
+a default configuration for your platform, run the following commands:
+
+ ./configure
+ make -s
+ make install
+
+There should be no errors and few, if any, warnings during the `make
+-s' stage. Any warnings about pointer mismatch or conversion should
+be treated with deep suspicion.
+
+The `make install' command may require `root' priviliges; for example,
+on some systems, the following modification to the command is needed:
+
+ sudo make install
+
+To run a selection of tests on the installed sox executable:
+
+ make installcheck
+
+Optionally, HTML & PDF versions of the manual pages can be built and
+installed as follows:
+
+ make html
+ make install-html
+ make pdf
+ make install-pdf
+
+Again, `root' priviliges may be needed at the install stages.
+
+
+
+Custom build options on a POSIX system
+--------------------------------------
+
+Selection of optional libraries and of other build options can be made
+by adding parameters to the `./configure' command line (above). Run
+
+ ./configure --help
+
+for a complete list of options.
+
+Each optional file-format may be configured to be loaded statically
+(the default) or dynamically. The dynamic option may be useful for
+distribution packaging reasons -- for example, to keep separate `free'
+and `non-free' software.
+
+If you are building SoX for a `distribution' (i.e. the build will be
+used by others), please use --with-distro to identify the distribution
+as this information is useful in helping to diagnose SoX bug reports.
+For example,
+
+ ./configure --with-distro='Super Linux OS 6.1'
+
+If any libraries are installed in a non-standard locations in your
+system then you can use the CPPFLAGS and LDFLAGS variables to allow
+configure to find them. For example:
+
+./configure CPPFLAGS="-I/home/sox/include -I/usr/local/multimedia/include" LDFLAGS="-L/home/sox/lib -L/usr/local/multimedia/lib"
+
+If you are compiling under cygwin and would like to create a static
+sox.exe using mingw libraries then you can use the following:
+
+./configure CC="gcc -mno-cygwin" --disable-shared
+
+The next cygwin example is used to build the cygwin version of SoX that is
+distributed by the project. It tells gcc to prefer static libraries
+over dynamic ones and to use some static libraries compiled manually
+and installed under /usr/local.
+
+./configure LDFLAGS="-static -L/usr/local/lib" CPPFLAGS=-I/usr/local/include
+
+You can run "cygcheck.exe src/sox.exe" after compiling to see which
+dynamic DLL's will be required to be distributed with the cygwin
+executable.
+
+Alternatively, you can make use of the "cygbuild" script distributed
+with SoX source that is used to automate all steps of building
+a win32 package. "osxbuild" script is used to automate all steps
+of building a MacOS X package.
+
+Newer versions of SoX include support for loading libraries for
+file formats at runtime. The main usage of this feature is to
+allow shipping SoX without dependencies on external libraries
+that are not globally used or have redistribution restrictions.
+If you experience problems with this then you may wish to disable
+this feature:
+
+./configure --without-libltdl
+
+Also, the default behavior even when libltdl is used is to link
+all file format handlers into libsox as there is a performance
+hit when dynamically loading external libraries. To force a format
+handler to be built as a dynamically loaded module, pass "dyn" to
+its --with-* option. For example, to build pulseaudio handler as
+an external dynamic library:
+
+./configure --with-pulseaudio=dyn
+
+A subset of external libraries can be configured to be dlopen()'ed
+at run time instead of being linked in. This will allow one to
+distribute a binary with optional features that only require
+a user to install the missing libraries into their system. This
+can be enabled using:
+
+--enable-dl-lame
+--enable-dl-mad
+--enable-dl-sndfile
+--enable-dl-amrnb
+--enable-dl-amrwb
+
+Testing
+-------
+
+N.B.: If SoX is configured and compiled to load some file-formats
+dynamically, then it will not be able to load them when running SoX
+executables from within the source file directory until after SoX has
+been installed (temporarily configuring with --without-libltdl removes
+this restriction).
+
+After successfully compiling SoX, try translating a sound file. You
+should also playback the new file to make sure it sounds like the
+original. You can either use an external program or SoX itself
+if compiled with playback support.
+
+To work with widest range of playback programs, you should chose a
+format that is native to your OS; such as .wav for Windows or .aiff for
+MacOS. In the following example, we'll use .xxx as the extension of
+your preferred format.
+
+ cd src
+ ./sox monkey.wav monkey.xxx
+
+You may have to give the word size and rate for the file. For example,
+this command will make a sound file with a data rate of 12,500 samples
+per second and the data formatted as 2-byte (16-bit) signed integers:
+
+ ./sox monkey.wav -r 12500 -2 -s monkey.xxx
+
+If playback support was compiled in then it can be played like this:
+
+ ./play monkey.xxx
+
+or, equivalently:
+
+ ./sox monkey.xxx -d
+
+If monkey.xxx plays properly (it's a very short monkey screech),
+congratulations! SoX works.
+
+If you're adding new features to SoX or want to perform advance tests
+on a new platform then you can use the scripts "tests.sh" and
+"testall.sh" to stress SoX.
+
+
+
+Compiling using Microsoft's Visual C
+------------------------------------
+
+To compile a full-featured build of SoX with Visual Studio 2008 (msvc9),
+Visual Studio 2010 (msvc10), or the Windows SDK 7.1, you may be able to use the
+preconfigured solution found in the sox\msvc9 (VS2008) or sox\msvc10 (VS2010 or
+Windows SDK 7.1) folder. See sox\msvc9\readme.txt or sox\msvc10\readme.txt for
+details on building using the corresponding Microsoft C compiler. If the
+preconfigured solution doesn't work for you, build with CMake as follows:
+
+o Install cmake (http://www.cmake.org/HTML/Download.html)
+o Install any optional libraries to use with SoX
+o Unpack the SoX sources (...tar.gz) to say c:\sox
+o Type cd c:\sox
+o Type cmake -G "compiler" . (type cmake --help for list of compilers)
+
+This should generate project build files for use with Visual C.
+
+
+
+Appendix: How To Compile SoX with MP3 Support on Win32
+------------------------------------------------------
+
+The solution files in msvc9 and msvc10 will build SoX to dynamically load
+libmad.dll and libmp3lame.dll at runtime.
+
+The following text, untested by the SoX team, was originally written
+by `Enter AG' and released to the public domain. It includes instructions for
+building SoX with MP3 support linked directly into the SoX executable.
+
+= How To Compile Sox with MP3 Support =
+
+== Requirements ==
+
+The following requirements have been tested. Nevertheless, other
+versions may work as well.
+
+o Microsoft Windows (Win32, Win2000, XP, Win2003, Vista, etc.).
+
+o CMake (Cross Platform Make) version 2.4
+ available on [http://www.cmake.org]
+
+o Microsoft Visual Stuio 2008 (earlier versions should also work).
+
+o SoX source distribution version 14.0.1
+ available on [http://sox.sourceforge.net]
+
+o LAME source distribution version 3.97. LAME 3.98 is required for full ID3 tag
+ support. Available on [http://lame.sourceforge.net]
+
+o MAD source distribution version 0.15.1b
+ available on [http://www.underbit.com/products/mad/]
+
+== Compilation Procedure ==
+
+=== Compilation of the LAME libraries ===
+
+o Extract the LAME source distribution and open it as a Visual Studio project
+ using the VS file in the top directory.
+
+o Set the ''libmp3lame'' "Configuration Properties -> C/C++ -> Code Generation
+ -> Runtime Library" to Multi-threaded DLL (/MD).
+
+o Do the same for ''mpglib'' .
+
+o Build ''libmp3lame'' and ''mpglib.''
+
+o Rename the static library libmp3lame.lib to mp3lame.lib.
+
+o Create a folder somewhere with an arbitrary name. We used the name
+ "lameforsox". Create in this folder a new folder called "lame" and copy the
+ lame.h header file into it. Copy mp3lame.lib and mpglib.lib in the lameforsox
+ folder. Now you should have prepared the lame components for further use like
+ this:
+ ...\[somewhere]\lameforsox\
+ mp3lame.lib
+ mpglib.lib
+ \lame\
+ lame.h
+
+=== Compilation of the MAD library ===
+
+o Compile ''libmad'' with the same "Runtime Library" settings as described for
+ LAME (previous section Compilation of the LAME libraries).
+
+o Rename the static library libmad.lib to mad.lib.
+
+=== Compilation of SoX with the LAME and MAD libraries ===
+
+o Open Visual Studio and add in "Tools -> Options -> Projects and Solutions ->
+ VC++ Directories" in the "Include Directories" collection the folder
+ containing the MAD header file mad.h and the folder containing lame/lame.h
+ (...\[somewhere]\lameforsox). Add in the "Library files" collection the
+ folder containing mad.lib and the folder containing the lame libraries
+ mp3lame.lib and mpglib.lib (...\[somewhere]\lameforsox).
+
+o Edit the CMakeLists.txt in the SoX top directory:
+ Add
+ set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} mpglib)
+ after some blank lines beneath the statement
+ if(NEED_LIBM)
+ set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} -lm)
+ endif(NEED_LIBM)
+
+o Open the windows command line console and change into the SoX top directory.
+
+o Execute cmake like this:
+ cmake.exe ./ -G "Visual Studio 9 2008"
+
+o If the Visual Studio settings are done as described above the following cmake
+ output should appear:
+ ...
+ include files HAVE_MAD_H1 - found
+ mad_stream_buffer in madmad_stream_buffer in mad - found
+ ...
+ include files HAVE_LAME_LAME_H1 - found
+ lame_init in mp3lamelame_init in mp3lame - found
+ ...
+
+o If not check CMakeFiles\CMakeError.log.
+
+o Open Visual Studio and open the SoX solution file in the SoX top directory
+ (sox.sln).
+
+o Rebuild "ALL_BUILD" and confirm all "File Modification Detected" dialogs
+ with "Reload".
+
+o Add in the libsox "Preprocessor Definitions" (right click on libsox ->
+ Properties -> Configuration Properties -> C/C++ -> Preprocessor) HAVE_STRING_H
+ before the first line. Set the "Runtime Library" to Multi-threaded DLL (/MD)
+ as described above.
+
+o Do the same for sox and add in the "Additional Dependencies" (Linker -> Input)
+ after the last line mpglib.lib.
+
+o Now build libsox
+
+o and then sox.
+
+o Sox now prompts "mp3, mp2" in the usage output in the section "SUPPORTED FILE
+ FORMATS".

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+

+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+Public License instead of this License.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>

+ SoX: Sound eXchange
+ ===================
+
+SoX (Sound eXchange) is the Swiss Army knife of sound processing tools: it
+can convert sound files between many different file formats & audio devices,
+and can apply many sound effects & transformations, as well as doing basic
+analysis and providing input to more capable analysis and plotting tools.
+
+SoX is licensed under the GNU GPL and GNU LGPL. To be precise, the 'sox'
+and 'soxi' programs are distributed under the GPL, while the library
+'libsox' (in which most of SoX's functionality resides) is dual-licensed.
+Note that some optional components of libsox are GPL only: if you use these,
+you must use libsox under the GPL. See INSTALL for the list of optional
+components and their licences.
+
+If this distribution is of source code (as opposed to pre-built binaries),
+then you will need to compile and install SoX as described in the 'INSTALL'
+file.
+
+Changes between this release and previous releases of SoX can be found in
+the 'ChangeLog' file; a summary of the file formats and effects supported in
+this release can be found below. Detailed documentation for using SoX can
+be found in the distributed 'man' pages:
+
+ o sox(1)
+ o soxi(1)
+ o soxformat(7)
+ o libsox(3)
+
+or in plain text or PDF files for those systems without man.
+
+The majority of SoX features and fixes are contributed by SoX users - thank
+you very much for making SoX a success! There are several new features
+wanted for SoX, listed on the feature request tracker at the SoX project
+home-page:
+
+ http://sourceforge.net/projects/sox
+
+users are encouraged to implement them!
+
+Please submit bug reports, new feature requests, and patches to the relevant
+tracker at the above address, or by email:

+SoX
+---
+
+This file contains information specific to the MacOS X version of SoX.
+Please refer to the README file for general information.
+
+The sox executable can be installed anywhere you desire. It is a
+self-contained statically linked executable.
+
+If the sox executable is invoked with an executable name of soxi, play,
+or rec it will perform the functions of those applications as defined
+in included documents. Symlinks are included with this package
+but you can also make your own.
+
+Acknowledgements

+
+Appendix - wget Support
+-----------------------
+
+SoX can make use of the wget command line utility to load files over
+the internet or listen to shoutcast streams. It only needs to be
+somewhere in your path to be used by SoX.
+
+Please consult wget's homepage for access to source code as well
+as further instructions on configuring and installing.
+
+http://www.gnu.org/software/wget
+
+Appendix - MP3 Support
+----------------------
+
+SoX contains support for reading and writing MP3 files but does not ship
+with the dylib's that perform decoding and encoding of MP3 data because
+of patent restrictions. For further details, refer to:
+
+http://en.wikipedia.org/wiki/MP3#Licensing_and_patent_issues
+
+MP3 support can be enabled by placing Lame encoding library and/or
+MAD decoding library into a standard library search location such
+as /usr/lib or set LTDL_LIBRARY_PATH to location.
+
+These can be compiled yourself, they may turn up on searches of the internet
+or may be included with other MP3 applications already installed
+on your system. Try searching for libmp3lame.dylib and libmad.dylib.
+
+Obtain the latest Lame and MAD source code from approprate locations.
+
+Lame MP3 encoder http://lame.sourceforge.net
+MAD MP3 decoder http://www.underbit.com/products/mad
+
+If your system is setup to compile software, then the following commands
+can be used. Note: since SoX is distributed as a 32-bit i386 binary,
+the library must match that format as well:
+
+cd lame-398-2
+./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386"
+make
+sudo make install
+
+cd libmad-0.15.1b
+./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386"
+make
+sudo make install
+
+Appendix - AMR-NB/AMR-WB Support
+--------------------------------
+
+SoX contains support for reading and writing AMR-NB and AMR-WB files but
+does not ship with the DLL's that perform decoding and encoding of AMR
+data because of patent restrictions.
+
+AMR-NB/AMR-WB support can be enabled by placing required libraries
+into a standard library search location such as /usr/lib
+or set LTDL_LIBRARY_PATH to search path.
+
+These can be compiled yourself, they may turn up on searches of the internet
+or may be included with other AMR applications already installed
+on your system. Try searching for libopencore-amrnb.dylib and
+libopencore-amrwb.dylib.
+
+Obtain the latest amrnb and amrwb source code from
+http://sourceforge.net/projects/opencore-amr
+
+cd opencore-amr-0.1.2
+./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386"
+make
+sudo make install
+
+If that does not work, then try this:
+
+cd opencore-amr-0.1.2
+./build_osx.sh
+
+Appendix - LADSPA Plugins
+-------------------------
+
+SoX has built in support for LADSPA Plugins. These plugins are
+mostly built for Linux but some are available for OS X.
+The Audacity GUI application has a page that points to a collection
+of OS X LADSPA plugins.
+
+http://audacity.sourceforge.net/download/plugins
+
+SoX will search for these plugins based on LADSPA_PATH
+enviornment variable. See sox.txt for further information.

+SoX
+---
+
+This file contains information specific to the Win32 version of SoX.
+Please refer to the README file for general information.
+
+The binary SOX.EXE can be installed anywhere you desire. The only
+restriction is that the included ZLIB1..DLL and LIBGOMP-1.DLL must be
+located in the same directory as SOX.EXE or somewhere within your PATH.
+
+SoX Helper Applications
+-----------------------
+
+SoX also includes support for SOXI.EXE, PLAY.EXE and REC.EXE and their
+behaviors are documented in included PDF's. They have the same
+install restrictions as SOX.EXE.
+
+SOXI.EXE, PLAY.EXE, and REC.EXE are not distributed with this package to
+reduce size requirements. They are, in fact, only copies of the original
+SOX.EXE binary which changes SOX.EXE's behavior based on the
+executable's filename.
+
+If you wish to make use of these utils then you can create them
+yourself.
+
+copy sox.exe soxi.exe
+copy sox.exe play.exe
+copy sox.exe rec.exe
+
+If you are concerned with disk space, the play and record
+functionality can be equated using the "-d" option with SOX.EXE. soxi
+functionality can be equated using the "--info" option with SOX.EXE. The
+rough syntax is:
+
+play: sox [input files and options] -d [effects]
+rec: sox -d [output file and options] [effects]
+soxi: sox --info [input files and options]

+http://en.wikipedia.org/wiki/MP3#Licensing_and_patent_issues
+
+MP3 support can be enabled by placing Lame encoding DLL and/or
+MAD decoding DLL into the same directory as SOX.EXE. These
+can be compiled yourself, they may turn up on searches of the internet
+or may be included with other MP3 applications already installed
+on your system. For encoding/writing, try searching for lame-enc.dll,
+libmp3lame-0.dll, libmp3lame.dll, or cygmp3lame-0.dll. For
+decoding/reading, try searching for libmad-0.dll, libmad.dll or cygmad-0.dll.
+
+Instructions are included here for using MSYS to create the DLL's.
+It is assumed you already have MSYS installed on your system
+with a working gcc compiler. The commands are ran from MSYS
+bash shell.
+
+Obtain the latest Lame and MAD source code from approprate locations.
+
+Lame MP3 encoder http://lame.sourceforge.net
+MAD MP3 decoder http://www.underbit.com/products/mad
+
+cd lame-398-2
+./configure --disabled-static --enable-shared
+make
+cp libmp3lame/.libs/libmp3lame-0.dll /path/to/sox
+
+MAD libraries up to 0.15.1b have a bug in configure that will not allow
+building DLL under mingw. This can be resolved by adding LDFLAGS
+to configure and editing the generated Makefile to remove an invalid
+option.
+
+cd libmad-0.15.1b
+./configure --enable-shared --disable-static LDFLAGS="-no-undefined"
+[edit Makefile, search for "-fforce-mem" and delete it.]
+make
+cp libmad-0.dll /path/to/sox/
+
+Appendix - AMR-NB/AMR-WB Support
+--------------------------------
+
+SoX contains support for reading and writing AMR-NB and AMR-WB files but
+does not ship with the DLL's that perform decoding and encoding of AMR
+data because of patent restrictions.
+
+AMR-NB/AMR-WB support can be enabled by placing required DLL's
+into the same directory as SOX.EXE. These can be compiled yourself,
+they may turn up on searches of the internet or may be included with other
+MP3 applications already installed on your system. For AMR-NB support,
+try searching for libamrnb-3.dll, libopencore-amrnb-0.dll, or
+libopencore-amrnb.dll. For AMR-WB support, try searching for libamrwb-3.dll,
+libopencore-amrwb-0.dll, or libopencore-amrwb.dll.
+
+Instructions are included here for using MSYS to create the DLL's.
+It is assumed you already have MSYS installed on your system with
+working gcc compiler. These commands are ran from MSYS bash shell.
+
+Obtain the latest amrnb and amrwb source code from
+http://sourceforge.net/projects/opencore-amr .
+
+cd opencore-amr-0.1.2
+./configure --enable-shared --disable-static LDFLAGS="-no-undefined"
+make
+cp amrnb/.libs/libopencore-amrnb-0.dll /path/to/sox
+cp amrwb/.libs/libopencore-amrwb-0.dll /path/to/sox
+
+Appendix - LADSPA Plugins
+-------------------------
+
+SoX has built in support for LADSPA Plugins. These plugins are
+mostly built for Linux but some are available for Windows.
+The Audacity GUI application has a page that points to a collection
+of Windows LADSPA plugins.
+
+http://audacity.sourceforge.net/download/plugins
+
+SoX will search for these plugins based on LADSPA_PATH
+enviornment variable. See sox.txt for further information.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+\`configure' configures SoX 14.4.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ PKG_CONFIG path to pkg-config utility
+ PKG_CONFIG_PATH
+ directories to add to pkg-config's search path
+ PKG_CONFIG_LIBDIR
+ path overriding pkg-config's built-in search path
+ OPUS_CFLAGS C compiler flags for OPUS, overriding pkg-config
+ OPUS_LIBS linker flags for OPUS, overriding pkg-config
+ SNDFILE_CFLAGS
+ C compiler flags for SNDFILE, overriding pkg-config
+ SNDFILE_LIBS
+ linker flags for SNDFILE, overriding pkg-config

+# This script will automates the steps used to producing a static win32
+# package of SoX.
+#
+# It requires cygwin with gcc and zip packages installed. Also, it
+# requires to already have several external libraries already installed
+# under /usr/local.
+#
+# And last, it will optional package a wget compiled with VC++ instead
+# of cygwin version (which has no DLL's to distribute) if found
+# in wget-1.11.4 directory. If not found, it will distribute the
+# cygwin version and various DLL's it requires.
+#
+# Various notes:
+#
+# Script makes use of "-static" option to tell compiler to prefer static
+# external libraries so that we do not need to distribute DLL's.
+#
+# Libtool will get confused with this flag for external libraries
+# that have a libtool lib*.la file and support shared libraries as
+# well as static libraries (but usually only if that library
+# further depends on other external libraries with lib*.la files).
+# Libtool may ignore -static option or it may link first external
+# library as static but other dependent libraries as shared (usually
+# because it follows $dependency_libs and that ignores -static option).
+#
+# Work arounds include to only install static libraries, delete the lib*.la
+# file, or edit the lib*.la file and set dlnames and library_names variables
+# to empty string ("").
+#
+# The following command lines were used to generate the static external
+# libraries SoX ships with.
+#
+# libpng.la will have libtool issue because depends on libz
+# which has a libz.la file. Must edit libpng.la to

+.SH DESCRIPTION
+.I libsox
+is a library of sound sample file format readers/writers and sound
+effects processors. It is mainly developed for use by SoX but is
+useful for any sound application.
+.P
+\fBsox_format_init\fR function performs some required initialization
+related to all file format handlers. If compiled with dynamic
+library support then this will detect and initialize all external
+libraries. This should be called before any other file operations
+are performed.
+.P
+\fBsox_format_quit\fR function performs some required cleanup
+related to all file format handlers.
+.P
+\fBsox_open_input\fR function opens the file for reading whose name is
+the string pointed to by \fIpath\fR and associates an sox_format_t with it. If
+\fIinfo\fR is non-NULL then it will be used to specify the data format
+of the input file. This is normally only needed for headerless audio
+files since the information is not stored in the file. If
+\fIfiletype\fR is non-NULL then it will be used to specify the file
+type. If this is not specified then the file type is attempted to be
+derived by looking at the file header and/or the filename extension. A
+special name of "-" can be used to read data from stdin.
+.P
+\fBsox_open_output\fR function opens the file for writing whose name is
+the string pointed to by \fIpath\fR and associates an sox_format_t with it. If
+\fIinfo\fR is non-NULL then it will be used to specify the data format
+of the output file. Since most file formats can write data in
+different data formats, this generally has to be specified. The info
+structure from the input format handler can be specified to copy data
+over in the same format. If \fIcomment\fR is non-NULL, it will be
+written in the file header for formats that support comments. If
+\fIfiletype\fR is non-NULL then it will be used to specify the file
+type. If this is not specified then the file type is attempted to be
+derived by looking at the filename extension. A special name of "-"
+can be used to write data to stdout.
+.P
+The function \fBsox_read\fR reads \fIlen\fR samples in to \fIbuf\fR
+using the format handler specified by \fIft\fR. All data read is
+converted to 32-bit signed samples before being placed in to
+\fIbuf\fR. The value of \fIlen\fR is specified in total samples. If
+its value is not evenly divisable by the number of channels, undefined
+behavior will occur.
+.P
+The function \fBsox_write\fR writes \fIlen\fR samples from \fIbuf\fR
+using the format handler specified by \fIft\fR. Data in \fIbuf\fR must
+be 32-bit signed samples and will be converted during the write
+process. The value of \fIlen\fR is specified in total samples. If its
+value is not evenly divisable by the number of channels, undefined
+behavior will occur.
+.P
+The \fBsox_close\fR function dissociates the named \fIsox_format_t\fR from its
+underlying file or set of functions. If the format handler was being
+used for output, any buffered data is written first.
+.P
+The function \fBsox_find_effect\fR finds effect \fIname\fR, returning
+a pointer to its \fIsox_effect_handler_t\fR if it exists, and NULL
+otherwise.
+.P
+The function \fBsox_create_effect\fR instantiates an effect into a
+\fIsox_effect_t\fR given a \fIsox_effect_handler_t *\fR. Any missing
+methods are automatically set to the corresponding \fBnothing\fR
+method.
+.P
+The function \fBsox_effect_options\fR allows passing options into the effect to control its behavior. It will return SOX_EOF if there were any invalid options passed in. On success, the \fIeffp->in_signal\fR will optional contain the rate and channel count it requires input data from and \fIeffp->out_signal\fR will optionally contain the rate and channel count it outputs in. When present, this information should be used to make sure appropriate effects are placed in the effects chain to handle any needed conversions.
+.P
+Passing in options is currently only supported when they are passed in before the effect is ever started. The behavior is undefined if its called once the effect is started.
+.P
+\fBsox_create_effects_chain\fR will instantiate an effects chain that
+effects can be added to. \fIin_enc\fR and \fIout_enc\fR are the
+signal encoding of the input and output of the chain respectively.
+The pointers to \fIin_enc\fR and \fIout_enc\fR
+are stored internally and so their memory should not be freed. Also,
+it is OK if their values change over time to reflect new input or
+output encodings as they are referenced only as effects
+start up or are restarted.
+.P
+\fBsox_delete_effects_chain\fR will release any resources reserved during
+the creation of the chain. This will also call \fBsox_delete_effects\fR
+if any effects are still in the chain.
+.P
+\fBsox_add_effect\fR adds an effect to the chain. \fIin\fR specifies the input
+signal info for this effect. \fIout\fR is a suggestion
+as to what the output signal should be but depending on the effects
+given options and on \fIin\fR the effect can choose to do differently.
+Whatever output rate and channels the effect does produce are written
+back to \fIin\fR. It is meant that \fIin\fR be stored and passed to each
+new call to \fBsox_add_effect\fR so that changes will be propagated to each new effect.
+.P
+SoX includes skeleton C files to assist you in writing new
+formats (skelform.c) and effects (skeleff.c). Note that new formats
+can often just deal with the header and then use raw.c's routines
+for reading and writing.
+
+example0.c and example1.c are a good starting point to see how
+to write applications using libsox. sox.c itself is also a good
+reference.
+
+.SH RETURN VALUE
+Upon successful completion \fBsox_open_input\fR and
+\fBsox_open_output\fR return an \fIsox_format_t\fR (which is a pointer).
+Otherwise, NULL is returned. TODO: Need a way to return reason for
+failures. Currently, relies on \fBsox_warn\fR to print information.
+.P
+\fBsox_read\fR and \fBsox_write\fR return the number of samples
+successfully read or written. If an error occurs, or the end-of-file
+is reached, the return value is a short item count or SOX_EOF. TODO:
+\fBsox_read\fR does not distiguish between end-of-file and error. Need
+an feof() and ferror() concept to determine which occured.
+.P
+Upon successful completion \fBsox_close\fR returns 0. Otherwise, SOX_EOF
+is returned. In either case, any further access (including another
+call to \fBsox_close\fR()) to the handler results in undefined
+behavior. TODO: Need a way to return reason for failures. Currently,
+relies on sox_warn to print information.
+.P
+Upon successful completion \fBsox_seek\fR returns 0. Otherwise, SOX_EOF
+is returned. TODO Need to set a global error and implement sox_tell.
+.SH ERRORS
+TODO
+.SH INTERNALS
+SoX's formats and effects operate with an internal sample format of
+signed 32-bit integer. The data processing routines are called with
+buffers of these samples, and buffer sizes which refer to the number
+of samples processed, not the number of bytes. File readers translate
+the input samples to signed 32-bit integers and return the number of
+samples read. For example, data in linear signed byte format is
+left-shifted 24 bits.
+.P
+Representing samples as integers can cause problems when processing the audio.
+For example, if an effect to
+mix down left and right channels into one monophonic channel
+were to use the line
+.EX
+ *obuf++ = (*ibuf++ + *ibuf++)/2;
+.EE
+distortion might occur since
+the intermediate addition can overflow 32 bits.
+The line
+.EX
+ *obuf++ = *ibuf++/2 + *ibuf++/2;
+.EE
+would get round the overflow problem (at the expense of the least significant
+bit).
+.P
+Stereo data is stored with the left and right speaker data in
+successive samples.
+Quadraphonic data is stored in this order:
+left front, right front, left rear, right rear.
+.SH FORMATS
+A
+.I format
+is responsible for translating between sound sample files
+and an internal buffer. The internal buffer is store in signed longs
+with a fixed sampling rate. The
+.I format
+operates from two data structures:
+a format structure, and a private structure.
+.P
+The format structure contains a list of control parameters for
+the sample: sampling rate, data size (8, 16, or 32 bits),
+encoding (unsigned, signed, floating point, etc.), number of sound channels.
+It also contains other state information: whether the sample file
+needs to be byte-swapped, whether sox_seek() will work, its suffix,
+its file stream pointer, its
+.I format
+pointer, and the
+.I private
+structure for the
+.I format .
+.P
+The
+.I private
+area is just a preallocated data array for the
+.I format
+to use however it wishes.
+It should have a defined data structure
+and cast the array to that structure.
+See voc.c for the use of a private data area.
+Voc.c has to track the number of samples it
+writes and when finishing, seek back to the beginning of the file
+and write it out.
+The private area is not very large.
+The ``echo'' effect has to malloc() a much larger area for its
+delay line buffers.
+.P
+A
+.I format
+has 6 routines:
+.TP 20
+startread
+Set up the format parameters, or read in
+a data header, or do what needs to be done.
+.TP 20
+read
+Given a buffer and a length:
+read up to that many samples,
+transform them into signed long integers,
+and copy them into the buffer.
+Return the number of samples actually read.
+.TP 20
+stopread
+Do what needs to be done.
+.TP 20
+startwrite
+Set up the format parameters, or write out
+a data header, or do what needs to be done.
+.TP 20
+write
+Given a buffer and a length:
+copy that many samples out of the buffer,
+convert them from signed longs to the appropriate
+data, and write them to the file.
+If it can't write out all the samples,
+fail.
+.TP 20
+stopwrite
+Fix up any file header, or do what needs to be done.
+.SH EFFECTS
+Each effect runs with one input and one output stream.
+An effect's implementation comprises six functions that may be called
+to the follow flow diagram:
+.EX
+LOOP (invocations with different parameters)
+ getopts
+ LOOP (invocations with the same parameters)
+ LOOP (channels)
+ start
+ LOOP (whilst there is input audio to process)
+ LOOP (channels)
+ flow
+ LOOP (whilst there is output audio to generate)
+ LOOP (channels)
+ drain
+ LOOP (channels)
+ stop
+ kill
+.EE
+Notes: For some effects, some of the functions may not be needed and can
+be NULL. An effect that is marked `MCHAN' does not use the LOOP
+(channels) lines and must therefore perform multiple channel processing
+inside the affected functions. Multiple effect instances may be
+processed (according to the above flow diagram) in parallel.
+.TP 20
+getopts
+is called with a character string argument list for the effect.
+.TP 20
+start
+is called with the signal parameters for the input and output
+streams.
+.TP 20
+flow
+is called with input and output data buffers,
+and (by reference) the input and output data buffer sizes.
+It processes the input buffer into the output buffer,
+and sets the size variables to the numbers of samples
+actually processed.
+It is under no obligation to read from the input buffer or
+write to the output buffer during the same call. If the
+call returns SOX_EOF then this should be used as an indication
+that this effect will no longer read any data and can be used
+to switch to drain mode sooner.
+.TP 20
+drain
+is called after there are no more input data samples.
+If the effect wishes to generate more data samples
+it copies the generated data into a given buffer
+and returns the number of samples generated.
+If it fills the buffer, it will be called again, etc.
+The echo effect uses this to fade away.
+.TP 20
+stop
+is called when there are no more input samples and no more output
+samples to process.
+It is typically used to release or close resources (e.g. allocated
+memory or temporary files) that were set-up in
+.IR start .
+See echo.c for an example.
+.TP 20
+kill
+is called to allow resources allocated by
+.I getopts
+to be released.
+See pad.c for an example.
+.SH LINKING
+The method of linking against libsox depends on how SoX was
+built on your system. For a static build, just link against the
+libraries as normal. For a dynamic build, you should use libtool to
+link with the correct linker flags. See the libtool manual for
+details; basically, you use it as:
+.EX
+ libtool \-\-mode=link gcc \-o prog /path/to/libsox.la
+.EE

+ input file. This is normally only needed for headerless audio files
+ since the information is not stored in the file. If filetype is non-
+ NULL then it will be used to specify the file type. If this is not
+ specified then the file type is attempted to be derived by looking at
+ the file header and/or the filename extension. A special name of "-"
+ can be used to read data from stdin.
+
+ sox_open_output function opens the file for writing whose name is the
+ string pointed to by path and associates an sox_format_t with it. If
+ info is non-NULL then it will be used to specify the data format of the
+ output file. Since most file formats can write data in different data
+ formats, this generally has to be specified. The info structure from
+ the input format handler can be specified to copy data over in the same
+ format. If comment is non-NULL, it will be written in the file header
+ for formats that support comments. If filetype is non-NULL then it will
+ be used to specify the file type. If this is not specified then the
+ file type is attempted to be derived by looking at the filename exten‐
+ sion. A special name of "-" can be used to write data to stdout.
+
+ The function sox_read reads len samples in to buf using the format han‐
+ dler specified by ft. All data read is converted to 32-bit signed sam‐
+ ples before being placed in to buf. The value of len is specified in
+ total samples. If its value is not evenly divisable by the number of
+ channels, undefined behavior will occur.
+
+ The function sox_write writes len samples from buf using the format
+ handler specified by ft. Data in buf must be 32-bit signed samples and
+ will be converted during the write process. The value of len is speci‐
+ fied in total samples. If its value is not evenly divisable by the num‐
+ ber of channels, undefined behavior will occur.
+
+ The sox_close function dissociates the named sox_format_t from its
+ underlying file or set of functions. If the format handler was being
+ used for output, any buffered data is written first.
+
+ The function sox_find_effect finds effect name, returning a pointer to
+ its sox_effect_handler_t if it exists, and NULL otherwise.
+
+ The function sox_create_effect instantiates an effect into a
+ sox_effect_t given a sox_effect_handler_t *. Any missing methods are
+ automatically set to the corresponding nothing method.
+
+ The function sox_effect_options allows passing options into the effect
+ to control its behavior. It will return SOX_EOF if there were any
+ invalid options passed in. On success, the effp->in_signal will
+ optional contain the rate and channel count it requires input data from
+ and effp->out_signal will optionally contain the rate and channel count
+ it outputs in. When present, this information should be used to make
+ sure appropriate effects are placed in the effects chain to handle any
+ needed conversions.
+
+ Passing in options is currently only supported when they are passed in
+ before the effect is ever started. The behavior is undefined if its
+ called once the effect is started.
+
+ sox_create_effects_chain will instantiate an effects chain that effects
+ can be added to. in_enc and out_enc are the signal encoding of the
+ input and output of the chain respectively. The pointers to in_enc and
+ out_enc are stored internally and so their memory should not be freed.
+ Also, it is OK if their values change over time to reflect new input or
+ output encodings as they are referenced only as effects start up or are
+ restarted.
+
+ sox_delete_effects_chain will release any resources reserved during the
+ creation of the chain. This will also call sox_delete_effects if any
+ effects are still in the chain.
+
+ sox_add_effect adds an effect to the chain. in specifies the input
+ signal info for this effect. out is a suggestion as to what the output
+ signal should be but depending on the effects given options and on in
+ the effect can choose to do differently. Whatever output rate and
+ channels the effect does produce are written back to in. It is meant
+ that in be stored and passed to each new call to sox_add_effect so that
+ changes will be propagated to each new effect.
+
+ SoX includes skeleton C files to assist you in writing new formats
+ (skelform.c) and effects (skeleff.c). Note that new formats can often
+ just deal with the header and then use raw.c's routines for reading and
+ writing.
+
+ example0.c and example1.c are a good starting point to see how to write
+ applications using libsox. sox.c itself is also a good reference.
+
+
+RETURN VALUE
+ Upon successful completion sox_open_input and sox_open_output return an
+ sox_format_t (which is a pointer). Otherwise, NULL is returned. TODO:
+ Need a way to return reason for failures. Currently, relies on sox_warn
+ to print information.
+
+ sox_read and sox_write return the number of samples successfully read
+ or written. If an error occurs, or the end-of-file is reached, the
+ return value is a short item count or SOX_EOF. TODO: sox_read does not
+ distiguish between end-of-file and error. Need an feof() and ferror()
+ concept to determine which occured.
+
+ Upon successful completion sox_close returns 0. Otherwise, SOX_EOF is
+ returned. In either case, any further access (including another call to
+ sox_close()) to the handler results in undefined behavior. TODO: Need a
+ way to return reason for failures. Currently, relies on sox_warn to
+ print information.
+
+ Upon successful completion sox_seek returns 0. Otherwise, SOX_EOF is
+ returned. TODO Need to set a global error and implement sox_tell.
+
+ERRORS
+ TODO
+
+INTERNALS
+ SoX's formats and effects operate with an internal sample format of
+ signed 32-bit integer. The data processing routines are called with
+ buffers of these samples, and buffer sizes which refer to the number of
+ samples processed, not the number of bytes. File readers translate the
+ input samples to signed 32-bit integers and return the number of sam‐
+ ples read. For example, data in linear signed byte format is left-
+ shifted 24 bits.
+
+ Representing samples as integers can cause problems when processing the
+ audio. For example, if an effect to mix down left and right channels
+ into one monophonic channel were to use the line
+ *obuf++ = (*ibuf++ + *ibuf++)/2;
+ distortion might occur since the intermediate addition can overflow 32
+ bits. The line
+ *obuf++ = *ibuf++/2 + *ibuf++/2;
+ would get round the overflow problem (at the expense of the least sig‐
+ nificant bit).
+
+ Stereo data is stored with the left and right speaker data in succes‐
+ sive samples. Quadraphonic data is stored in this order: left front,
+ right front, left rear, right rear.
+
+FORMATS
+ A format is responsible for translating between sound sample files and
+ an internal buffer. The internal buffer is store in signed longs with
+ a fixed sampling rate. The format operates from two data structures: a
+ format structure, and a private structure.
+
+ The format structure contains a list of control parameters for the sam‐
+ ple: sampling rate, data size (8, 16, or 32 bits), encoding (unsigned,
+ signed, floating point, etc.), number of sound channels. It also con‐
+ tains other state information: whether the sample file needs to be
+ byte-swapped, whether sox_seek() will work, its suffix, its file stream
+ pointer, its format pointer, and the private structure for the format .
+
+ The private area is just a preallocated data array for the format to
+ use however it wishes. It should have a defined data structure and
+ cast the array to that structure. See voc.c for the use of a private
+ data area. Voc.c has to track the number of samples it writes and when
+ finishing, seek back to the beginning of the file and write it out.
+ The private area is not very large. The ``echo'' effect has to mal‐
+ loc() a much larger area for its delay line buffers.
+
+ A format has 6 routines:
+
+ startread Set up the format parameters, or read in a data
+ header, or do what needs to be done.
+
+ read Given a buffer and a length: read up to that many
+ samples, transform them into signed long integers,
+ and copy them into the buffer. Return the number
+ of samples actually read.
+
+ stopread Do what needs to be done.
+
+ startwrite Set up the format parameters, or write out a data
+ header, or do what needs to be done.
+
+ write Given a buffer and a length: copy that many samples
+ out of the buffer, convert them from signed longs
+ to the appropriate data, and write them to the
+ file. If it can't write out all the samples, fail.
+
+ stopwrite Fix up any file header, or do what needs to be
+ done.
+
+EFFECTS
+ Each effect runs with one input and one output stream. An effect's
+ implementation comprises six functions that may be called to the follow
+ flow diagram:
+ LOOP (invocations with different parameters)
+ getopts
+ LOOP (invocations with the same parameters)
+ LOOP (channels)
+ start
+ LOOP (whilst there is input audio to process)
+ LOOP (channels)
+ flow
+ LOOP (whilst there is output audio to generate)
+ LOOP (channels)
+ drain
+ LOOP (channels)
+ stop
+ kill
+ Notes: For some effects, some of the functions may not be needed and
+ can be NULL. An effect that is marked `MCHAN' does not use the LOOP
+ (channels) lines and must therefore perform multiple channel processing
+ inside the affected functions. Multiple effect instances may be pro‐
+ cessed (according to the above flow diagram) in parallel.
+
+ getopts is called with a character string argument list for
+ the effect.
+
+ start is called with the signal parameters for the input
+ and output streams.
+
+ flow is called with input and output data buffers, and
+ (by reference) the input and output data buffer
+ sizes. It processes the input buffer into the out‐
+ put buffer, and sets the size variables to the num‐
+ bers of samples actually processed. It is under no
+ obligation to read from the input buffer or write
+ to the output buffer during the same call. If the
+ call returns SOX_EOF then this should be used as an
+ indication that this effect will no longer read any
+ data and can be used to switch to drain mode
+ sooner.
+
+ drain is called after there are no more input data sam‐
+ ples. If the effect wishes to generate more data
+ samples it copies the generated data into a given
+ buffer and returns the number of samples generated.
+ If it fills the buffer, it will be called again,
+ etc. The echo effect uses this to fade away.
+
+ stop is called when there are no more input samples and
+ no more output samples to process. It is typically
+ used to release or close resources (e.g. allocated
+ memory or temporary files) that were set-up in
+ start. See echo.c for an example.
+
+ kill is called to allow resources allocated by getopts
+ to be released. See pad.c for an example.
+
+LINKING
+ The method of linking against libsox depends on how SoX was built on
+ your system. For a static build, just link against the libraries as
+ normal. For a dynamic build, you should use libtool to link with the
+ correct linker flags. See the libtool manual for details; basically,
+ you use it as:
+ libtool --mode=link gcc -o prog /path/to/libsox.la
+
+BUGS
+ This manual page is both incomplete and out of date.

+
+Before you can make any of the programs in this directory, you must
+change to the lpc10 directory and make the LPC-10 library. See the
+README file there, and be especially sure to read the notes there
+about possible modifications you will need to make to the file lpc10.h
+in this directory.
+
+I've made up a Unix makefile for the programs nuke and unnuke, called
+makefile.unx. I don't know how to create a makefile for Microsoft C.
+Feel free to send me one if you create one that works.
+
+The files in this directory are just some simple main programs that
+call the routines create_lpc10_encoder_state(), lpc10_encode(),
+create_lpc10_decoder_state(), and lpc10_decode(). Those four routines
+are defined in source files within the subdirectory lpc10, and are all
+that any application ever needs to use to compress and decompress
+speech with the LPC-10 coder. The main programs in this directory are
+just intended as examples of how to use these routines.
+
+Optionally, an application could also use the routines
+init_lpc10_encoder_state() or init_lpc10_decoder_state() to
+reinitialize a state struct that was created by one of the create
+functions mentioned above. This could be useful between talk spurts,
+for example, to flush out any possible remaining garbage state that
+could occur because some data was lost. This shouldn't be necessary,
+since any old bad state should be flushed out or decay within a few
+frame times anyway (frame time = 22.5 ms). I have heard lost packets
+(or maybe they were garbled?) produce interesting audio artifacts in
+the application Nautilus.

+
+I have just completed making many changes to the C source code that
+allow multiple audio streams to be compressed or decompressed in an
+interleaved fashion. This is useful, for example, for some Internet
+MBONE audio tools that can receive compressed audio from multiple
+sources simultaneously. See one or more of the following
+demonstration programs for examples of the calling sequence:
+
+nuke - compressing one audio stream
+nuke2 - compressing two audio streams, alternating one frame from each
+unnuke - decompressing one audio stream
+unnuke2 - decompressing two audio streams, alternating one frame from each

+ Calling sequence:
+
+ Call create_lpc10_encoder_state(), which returns a pointer to an
+ already initialized lpc10_encoder_state structure.
+
+ lpc10_encode reads indices 0 through (LPC10_SAMPLES_PER_FRAME-1) of
+ array speech[], and writes indices 0 through
+ (LPC10_BITS_IN_COMPRESSED_FRAME-1) of array bits[], and both reads
+ and writes the lpc10_encoder_state structure contents. The
+ lpc10_encoder_state structure should *not* be initialized for every
+ frame of encoded speech. Once at the beginning of execution, done
+ automatically for you by create_lpc10_encoder_state(), is enough.
+
+ init_lpc10_encoder_state() reinitializes the lpc10_encoder_state
+ structure. This might be useful if you are finished processing one
+ sound sample, and want to reuse the same lpc10_encoder_state
+ structure to process another sound sample. There might be other
+ uses as well.
+
+ Note that the comments in the lpc10/lpcenc.c file imply that indices
+ 1 through 180 of array speech[] are read. These comments were
+ written for the Fortran version of the code, before it was
+ automatically converted to C by the conversion program f2c. f2c
+ seems to use the convention that the pointers to arrays passed as
+ function arguments point to the first index used in the Fortran
+ code, whatever index that might be (usually 1), and then it modifies
+ the pointer inside of the function, like so:
+
+ if (speech) {
+ --speech;
+ }
+
+ So that the code can access the first value at index 1 and the last
+ at index 180. This makes the translated C code "closer" to the
+ original Fortran code.
+
+ The calling sequence for the decoder is similar to the encoder. The
+ only significant difference is that the array bits[] is read
+ (indices 0 through (LPC10_BITS_IN_COMPRESSED_FRAME-1)), and the
+ array speech[] is written (indices 0 through
+ (LPC10_SAMPLES_PER_FRAME-1)).

+/* Voicing Detection (VOICIN) makes voicing decisions for each half */
+/* frame of input speech. Tentative voicing decisions are made two frames*/
+/* in the future (2F) for each half frame. These decisions are carried */
+/* through one frame in the future (1F) to the present (P) frame where */
+/* they are examined and smoothed, resulting in the final voicing */
+/* decisions for each half frame. */
+/* The voicing parameter (signal measurement) column vector (VALUE) */
+/* is based on a rectangular window of speech samples determined by the */
+/* window placement algorithm. The voicing parameter vector contains the*/
+/* AMDF windowed maximum-to-minimum ratio, the zero crossing rate, energy*/
+/* measures, reflection coefficients, and prediction gains. The voicing */
+/* window is placed to avoid contamination of the voicing parameter vector*/
+/* with speech onsets. */
+/* The input signal is then classified as unvoiced (including */
+/* silence) or voiced. This decision is made by a linear discriminant */
+/* function consisting of a dot product of the voicing decision */
+/* coefficient (VDC) row vector with the measurement column vector */
+/* (VALUE). The VDC vector is 2-dimensional, each row vector is optimized*/
+/* for a particular signal-to-noise ratio (SNR). So, before the dot */
+/* product is performed, the SNR is estimated to select the appropriate */
+/* VDC vector. */
+/* The smoothing algorithm is a modified median smoother. The */
+/* voicing discriminant function is used by the smoother to determine how*/
+/* strongly voiced or unvoiced a signal is. The smoothing is further */
+/* modified if a speech onset and a voicing decision transition occur */
+/* within one half frame. In this case, the voicing decision transition */
+/* is extended to the speech onset. For transmission purposes, there are*/
+/* constraints on the duration and transition of voicing decisions. The */
+/* smoother takes these constraints into account. */
+/* Finally, the energy estimates are updated along with the dither */
+/* threshold used to calculate the zero crossing rate (ZC). */

+dnl Useful macros for autoconf to check for ssp-patched gcc
+dnl 1.0 - September 2003 - Tiago Sousa <mirage@kaotik.org>
+dnl 1.1 - August 2006 - Ted Percival <ted@midg3t.net>
+dnl * Stricter language checking (C or C++)
+dnl * Adds GCC_STACK_PROTECT_LIB to add -lssp to LDFLAGS as necessary
+dnl * Caches all results
+dnl * Uses macros to ensure correct ouput in quiet/silent mode
+dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>
+dnl * Added GCC_STACK_PROTECTOR macro for simpler (one-line) invocation
+dnl * GCC_STACK_PROTECT_LIB now adds -lssp to LIBS rather than LDFLAGS
+dnl
+dnl About ssp:
+dnl GCC extension for protecting applications from stack-smashing attacks
+dnl http://www.research.ibm.com/trl/projects/security/ssp/
+dnl
+dnl Usage:
+dnl Most people will simply call GCC_STACK_PROTECTOR.
+dnl If you only use one of C or C++, you can save time by only calling the
+dnl macro appropriate for that language. In that case you should also call
+dnl GCC_STACK_PROTECT_LIB first.
+dnl
+dnl GCC_STACK_PROTECTOR
+dnl Tries to turn on stack protection for C and C++ by calling the following
+dnl three macros with the right languages.
+dnl
+dnl GCC_STACK_PROTECT_CC
+dnl checks -fstack-protector with the C compiler, if it exists then updates
+dnl CFLAGS and defines ENABLE_SSP_CC
+dnl
+dnl GCC_STACK_PROTECT_CXX
+dnl checks -fstack-protector with the C++ compiler, if it exists then updates
+dnl CXXFLAGS and defines ENABLE_SSP_CXX
+dnl
+dnl GCC_STACK_PROTECT_LIB
+dnl adds -lssp to LIBS if it is available
+dnl ssp is usually provided as part of libc, but was previously a separate lib
+dnl It does not hurt to add -lssp even if libc provides SSP - in that case
+dnl libssp will simply be ignored.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+.SH DESCRIPTION
+.SS Introduction
+SoX reads and writes audio files in most popular formats and can
+optionally apply effects to them. It can combine multiple input
+sources, synthesise audio, and, on many systems, act as a general
+purpose audio player or a multi-track audio recorder. It also has
+limited ability to split the input into multiple output files.
+.SP
+All SoX functionality is available using just the \fBsox\fR command.
+To simplify playing and recording audio, if SoX is invoked as
+\fBplay\fR, the output file is automatically set to be the default sound
+device, and if invoked as \fBrec\fR, the default sound device is used as an
+input source.
+Additionally, the
+.BR soxi (1)
+command provides a convenient way to just query audio file header information.
+.SP
+The heart of SoX is a library called libSoX. Those interested in
+extending SoX or using it in other programs should refer to the libSoX
+manual page:
+.BR libsox (3).
+.SP
+SoX is a command-line audio processing tool, particularly suited to making
+quick, simple edits and to batch processing.
+If you need an interactive, graphical audio editor, use
+.BR audacity (1).

+Note however, that on the SoX command line, the positions of the
+Output(s) and the Effects are swapped w.r.t. the logical flow just
+shown. Note also that whilst options pertaining to files are placed
+before their respective file name, the opposite is true for effects.
+To show how this works in practice, here is a selection of examples of
+how SoX might be used. The simple

+.EE
+translates an audio file in Sun AU format to a Microsoft WAV file, whilst
+.EX

+records a stream of audio such as LP/cassette and splits in to multiple
+audio files at points with 2 seconds of silence. Also, it does not start
+recording until it detects audio is playing and stops after it sees
+10 minutes of silence.
+.SP
+N.B. The above is just an overview of SoX's capabilities; detailed
+explanations of how to use \fIall\fR SoX parameters, file formats, and
+effects can be found below in this manual, in
+.BR soxformat (7),
+and in
+.BR soxi (1).
+.SS File Format Types
+SoX can work with `self-describing' and `raw' audio files.
+`self-describing' formats (e.g. WAV, FLAC, MP3) have a header that
+completely describes the signal and encoding attributes of the audio
+data that follows. `raw' or `headerless' formats do not contain this
+information, so the audio characteristics of these must be described
+on the SoX command line or inferred from those of the input file.
+.SP
+The following four characteristics are used to describe the format of
+audio data such that it can be processed with SoX:
+.TP
+sample rate
+The sample rate in samples per second (`Hertz' or `Hz').
+Digital telephony traditionally uses a sample rate of 8000\ Hz (8\ kHz),
+though these days, 16 and even 32\ kHz are becoming more common. Audio
+Compact Discs use 44100\ Hz (44\*d1\ kHz). Digital Audio Tape and many
+computer systems use 48\ kHz. Professional audio systems often use 96
+kHz.
+.TP
+sample size
+The number of bits used to store each sample. Today, 16-bit is
+commonly used. 8-bit was popular in the early days of computer
+audio. 24-bit is used in the professional audio arena. Other sizes are
+also used.
+.TP
+data encoding
+The way in which each audio sample is represented (or `encoded'). Some
+encodings have variants with different byte-orderings or bit-orderings.
+Some compress the audio data so that the stored audio data takes up less
+space (i.e. disk space or transmission bandwidth) than the other format
+parameters and the number of samples would imply. Commonly-used
+encoding types include floating-point, \(*m-law, ADPCM, signed-integer
+PCM, MP3, and FLAC.
+.TP
+channels
+The number of audio channels contained in the file. One (`mono') and
+two (`stereo') are widely used. `Surround sound' audio typically
+contains six or more channels.
+.PP
+The term `bit-rate' is a measure of the amount of storage occupied by an
+encoded audio signal over a unit of time. It can depend on all of the
+above and is typically denoted as a number of kilo-bits per second
+(kbps). An A-law telephony signal has a bit-rate of 64 kbps. MP3-encoded
+stereo music typically has a bit-rate of 128\-196 kbps. FLAC-encoded
+stereo music typically has a bit-rate of 550\-760 kbps.
+.SP
+Most self-describing formats also allow textual `comments' to be
+embedded in the file that can be used to describe the audio in some way,
+e.g. for music, the title, the author, etc.
+.SP
+One important use of audio file comments is to convey `Replay Gain'
+information. SoX supports applying Replay Gain information (for certain
+input file formats only; currently, at least FLAC and Ogg Vorbis), but not
+generating it. Note that by default, SoX copies input file comments
+to output files that support comments, so output files may contain
+Replay Gain information if some was present in the input file. In this
+case, if anything other than a simple format conversion was performed
+then the output file Replay Gain information is likely to be incorrect
+and so should be recalculated using a tool that supports this (not SoX).
+.SP
+The
+.BR soxi (1)
+command can be used to display information from audio file headers.
+.SS Determining & Setting The File Format
+There are several mechanisms available for SoX to use to determine or set the
+format characteristics of an audio file. Depending on the circumstances,
+individual characteristics may be determined or set using different mechanisms.
+.SP
+To determine the format of an input file, SoX will use, in order of
+precedence and as given or available:
+.IP 1. 4
+Command-line format options.
+.IP 2. 4
+The contents of the file header.
+.IP 3. 4
+The filename extension.
+.PP
+To set the output file format, SoX will use, in order of
+precedence and as given or available:
+.IP 1. 4
+Command-line format options.
+.IP 2. 4
+The filename extension.
+.IP 3. 4
+The input file format characteristics, or the closest
+that is supported by the output file type.
+.PP
+For all files, SoX will exit with an error
+if the file type cannot be determined. Command-line format options may
+need to be added or changed to resolve the problem.
+.SS Playing & Recording Audio
+The
+.B play
+and
+.B rec
+commands are provided so that basic playing and
+recording is as simple as
+.EX
+ play existing-file.wav
+.EE
+and
+.EX
+ rec new-file.wav
+.EE
+These two commands are functionally equivalent to
+.EX
+ sox existing-file.wav \-d
+.EE
+and
+.EX
+ sox \-d new-file.wav
+.EE
+Of course, further options and effects (as described below) can be
+added to the commands in either form.
+.TS
+center;
+c8 c8 c.
+* * *
+.TE
+.DT
+.SP
+Some systems provide more than one type of (SoX-compatible) audio
+driver, e.g. ALSA & OSS, or SUNAU & AO.
+Systems can also have more than one audio device (a.k.a. `sound card').
+If more than one audio driver has been
+built-in to SoX, and the default selected by SoX when recording or playing
+is not the one that is wanted, then the
+.B AUDIODRIVER
+environment variable can be used to override the default. For example
+(on many systems):
+.EX
+ set AUDIODRIVER=oss
+ play ...
+.EE
+The
+.B AUDIODEV
+environment variable can be used to override the default audio device,
+e.g.
+.EX
+ set AUDIODEV=/dev/dsp2
+ play ...
+ sox ... \-t oss
+.EE
+or
+.EX
+ set AUDIODEV=hw:soundwave,1,2
+ play ...
+ sox ... \-t alsa
+.EE
+Note that the way of setting environment variables varies from system
+to system\*mfor some specific examples, see `SOX_OPTS' below.
+.SP
+When playing a file with a sample rate that is not supported by the
+audio output device, SoX will automatically invoke the \fBrate\fR effect
+to perform the necessary sample rate conversion. For
+compatibility with old hardware, the
+default \fBrate\fR quality level is set to `low'. This
+can be changed by explicitly specifying the \fBrate\fR
+effect with a different quality level, e.g.
+.EX
+ play ... rate \-m
+.EE
+or by using the
+.B \-\-play\-rate\-arg
+option (see below).
+.TS
+center;
+c8 c8 c.
+* * *
+.TE
+.DT
+.SP
+On some systems, SoX allows audio playback volume to be adjusted whilst
+using
+.BR play .
+Where supported, this is achieved by tapping the `v' & `V' keys during
+playback.
+.SP
+To help with setting a suitable recording level, SoX includes a peak-level
+meter which can be invoked (before making the actual recording) as follows:
+.EX
+ rec \-n
+.EE
+The recording level should be adjusted (using the system-provided mixer
+program, not SoX) so that the meter is \fIat most occasionally\fR full
+scale, and never `in the red' (an exclamation mark is shown).
+See also \fB\-S\fR below.
+.SS Accuracy
+Many file formats that compress audio discard some of the audio signal
+information whilst doing so. Converting to such a format and then converting
+back again will not produce an exact copy of the original audio. This
+is the case for many formats used in telephony (e.g. A-law, GSM) where
+low signal bandwidth is more important than high audio fidelity, and for
+many formats used in portable music players (e.g. MP3, Vorbis) where
+adequate fidelity can be retained even with the large compression ratios
+that are needed to make portable players practical.
+.SP
+Formats that discard audio signal information are called `lossy'.
+Formats that do not are called `lossless'. The term `quality' is used as a
+measure of how closely the original audio signal can be reproduced when
+using a lossy format.
+.SP
+Audio file conversion with SoX is lossless when it can be, i.e. when not
+using lossy compression, when not reducing the sampling rate or number
+of channels, and when the number of bits used in the destination format
+is not less than in the source format. E.g. converting from an 8-bit
+PCM format to a 16-bit PCM format is lossless but converting from an
+8-bit PCM format to (8-bit) A-law isn't.
+.SP
+.B N.B.
+SoX converts all audio files to an internal uncompressed
+format before performing any audio processing. This means that
+manipulating a file that is stored in a lossy format can cause further
+losses in audio fidelity. E.g. with
+.EX
+ sox long.mp3 short.mp3 trim 10
+.EE
+SoX first decompresses the input MP3 file, then applies the
+.B trim
+effect, and finally creates the output MP3 file by re-compressing the
+audio\*mwith a possible reduction in fidelity above that which
+occurred when the input file was created.
+Hence, if what is ultimately desired is lossily compressed audio, it is
+highly recommended to perform all audio processing using lossless file
+formats and then convert to the lossy format only at the final stage.
+.SP
+.B N.B.
+Applying multiple effects with a single SoX invocation will,
+in general, produce more accurate results than those produced using
+multiple SoX invocations.
+.SS Dithering
+Dithering is a technique used to maximise the dynamic range of audio
+stored at a particular bit-depth. Any distortion introduced by
+quantisation is decorrelated by adding a small amount of white noise
+to the signal. In most cases, SoX can determine whether the selected
+processing requires dither and will add it during output formatting if
+appropriate.
+.SP
+Specifically, by default, SoX automatically adds TPDF dither
+when the output bit-depth is less than 24 and any
+of the following are true:
+.IP \(bu 4
+bit-depth reduction has been specified explicitly using a command-line
+option
+.IP \(bu 4
+the output file format supports only bit-depths lower than that of the
+input file format
+.IP \(bu 4
+an effect has increased effective bit-depth within the internal
+processing chain
+.PP
+For example, adjusting volume with
+.B vol 0.25
+requires two additional bits in which to losslessly store its results
+(since 0\*d25 decimal equals 0\*d01 binary). So if the input file
+bit-depth is 16, then SoX's internal representation will utilise 18
+bits after processing this volume change. In order to store the
+output at the same depth as the input, dithering is used to remove the
+additional bits.
+.SP
+Use the
+.B \-V
+option to see what processing SoX has automatically added. The
+.B \-D
+option may be given to override automatic dithering. To invoke
+dithering manually (e.g. to select a noise-shaping curve), see the
+.B dither
+effect.
+.SS Clipping
+Clipping is distortion that occurs when an audio signal level (or
+`volume') exceeds the range of the chosen representation. In most
+cases, clipping is undesirable and so should be corrected by adjusting
+the level prior to the point (in the processing chain) at which it
+occurs.
+.SP
+In SoX, clipping could occur, as you might expect, when using the
+.B vol
+or
+.B gain
+effects to increase the audio volume. Clipping could also occur with many
+other effects, when converting one format to another, and even when
+simply playing the audio.
+.SP
+Playing an audio file often involves resampling, and processing by
+analogue components can introduce a small DC offset and/or
+amplification, all of which can produce distortion if the audio signal
+level was initially too close to the clipping point.
+.SP
+For these reasons, it is usual to make sure that an audio
+file's signal level has some `headroom', i.e. it does not exceed a particular
+level below the maximum possible level for the given representation.
+Some standards bodies recommend as much as 9dB headroom, but in most cases,
+3dB (\(~~ 70% linear) is enough. Note that this wisdom
+seems to have been lost in modern music production; in fact, many CDs,
+MP3s, etc. are now mastered at levels \fIabove\fR 0dBFS i.e. the
+audio is clipped as delivered.
+.SP
+SoX's
+.B stat
+and
+.B stats
+effects can assist in determining the signal level in an audio file. The
+.B gain
+or
+.B vol
+effect can be used to prevent clipping, e.g.
+.EX
+ sox dull.wav bright.wav gain \-6 treble +6
+.EE
+guarantees that the treble boost will not clip.
+.SP
+If clipping occurs at any point during processing,
+SoX will display a warning message to that effect.
+.SP
+See also
+.B \-G
+and the
+.B gain
+and
+.B norm
+effects.
+.SS Input File Combining
+SoX's input combiner can be configured (see OPTIONS below) to
+combine multiple files using any of the
+following methods: `concatenate', `sequence', `mix', `mix-power',
+`merge', or `multiply'.
+The default method is `sequence' for
+.BR play ,
+and `concatenate' for
+.B rec
+and
+.BR sox .
+.SP
+For all methods other than `sequence', multiple input files must have
+the same sampling rate. If necessary, separate SoX invocations can be
+used to make sampling rate adjustments prior to combining.
+.SP
+If the `concatenate' combining method is selected (usually, this will be
+by default) then the input files must also have the same number of
+channels. The audio from each input will be concatenated in the order
+given to form the output file.
+.SP
+The `sequence' combining method is selected automatically for
+.BR play .
+It is similar to `concatenate' in that the audio from each input file is
+sent serially to the output file. However, here the output file may be
+closed and reopened at the corresponding transition between input
+files. This may be just what is needed when sending different types of
+audio to an output device, but is not generally useful when the output is a
+normal file.
+.SP
+If either the `mix' or `mix-power' combining method is selected then two or
+more input files must be given and will be mixed together to form the
+output file. The number of channels in each input file need not be the
+same, but SoX will issue a warning if they are not and some
+channels in the output file will not contain audio from every input
+file. A mixed audio file cannot be un-mixed without reference to the
+original input files.
+.SP
+If the `merge' combining method is selected then two or
+more input files must be given and will be merged together to form the
+output file. The number of channels in each input file need not be the
+same. A merged audio file comprises all of the channels from all of the
+input files. Un-merging is possible using multiple
+invocations of SoX with the
+.B remix
+effect.
+For example, two mono files could be merged to form one stereo file. The
+first and second mono files would become the left and right channels of
+the stereo file.
+.SP
+The `multiply' combining method multiplies the sample values of
+corresponding channels (treated as numbers in the interval \-1 to +1).
+If the number of channels in the input files is not the same, the
+missing channels are considered to contain all zero.
+.SP
+When combining input files, SoX applies any specified effects
+(including, for example, the
+.B vol
+volume adjustment effect) after the audio has been combined. However, it
+is often useful to be able to set the volume of (i.e. `balance') the
+inputs individually, before combining takes place.
+.SP
+For all combining methods, input
+file volume adjustments can be made manually using the
+.B \-v
+option (below) which can be given for one or more input files. If it is
+given for only some of the input files then the others receive no volume
+adjustment. In some circumstances, automatic volume
+adjustments may be applied (see below).
+.SP
+The \fB\-V\fR option (below) can be used to show the input file volume
+adjustments that have been selected (either manually or automatically).
+.SP
+There are some special considerations that need to made when mixing
+input files:
+.SP
+Unlike the other methods, `mix' combining has the
+potential to cause clipping in the combiner if no balancing is
+performed. In this case, if manual volume adjustments are not given,
+SoX will try to ensure that clipping does not occur by automatically
+adjusting the
+volume (amplitude) of each input signal by a factor of \(S1/\s-2n\s+2,
+where n is the number of input files. If this results in audio that is
+too quiet or otherwise unbalanced then the input file volumes can be
+set manually as described above. Using the
+.B norm
+effect on the mix is another alternative.
+.SP
+If mixed audio seems loud enough at some points but
+too quiet in others then dynamic range compression should be applied to
+correct this\*msee the
+.B compand
+effect.
+.SP
+With the `mix-power' combine method, the
+mixed volume is approximately equal to that of one of the input signals.
+This is achieved by balancing using a factor of
+\(S1/\s-2\(srn\s+2 instead of \(S1/\s-2n\s+2.
+Note that this balancing factor does not guarantee that clipping will not occur,
+but the number of clips will usually be low and the resultant
+distortion is generally imperceptible.
+.SS Output Files
+SoX's default behaviour is to take one or more input files and
+write them to a single output file.
+
+This behaviour can be changed by specifying the pseudo-effect `newfile'
+within the effects list. SoX will then enter multiple output mode.
+
+In multiple output mode, a new file is created when the effects
+prior to the `newfile' indicate they are done.
+The effects chain listed after `newfile'
+is then started up and its output is saved to the new file.
+
+In multiple output mode, a unique number will automatically be appended
+to the end of all filenames. If the filename has an extension
+then the number is inserted before the extension. This behaviour can
+be customized by placing a %n anywhere in the filename where the
+number should be substituted. An optional number can be placed after
+the % to indicate a minimum fixed width for the number.
+
+Multiple output mode is not very useful unless an effect that will
+stop the effects chain early is
+specified before the `newfile'. If end of file is
+reached before the effects chain stops itself then no new file
+will be created as it would be empty.
+
+The following is an example of splitting the first 60 seconds of an input
+file into two 30 second files and ignoring the rest.
+.EX
+ sox song.wav ringtone%1n.wav trim 0 30 : newfile : trim 0 30
+.SS Stopping SoX
+Usually SoX will complete its processing and exit automatically once
+it has read all available audio data from the input files.
+.SP
+If desired, it can be terminated earlier by sending an
+interrupt signal to the process (usually by pressing the
+keyboard interrupt key which is normally Ctrl-C). This is a natural requirement
+in some circumstances, e.g. when using SoX to make a recording. Note
+that when using SoX to play multiple files, Ctrl-C behaves slightly
+differently: pressing it once causes SoX to skip to the next file;
+pressing it twice in quick succession causes SoX to exit.
+.SP
+Another option to stop processing early is to use an effect that
+has a time period or sample count to determine the stopping
+point. The trim effect is an example of this. Once all
+effects chains have stopped then SoX will also stop.
+.SH FILENAMES
+Filenames can be simple file names, absolute or relative path names,
+or URLs (input files only). Note that URL support requires that
+.BR wget (1)
+is available.
+.SP
+Note:
+Giving SoX an input or output filename that is the same as a SoX
+effect-name will not work since SoX will treat it as an effect
+specification. The only work-around to this is to avoid such
+filenames. This is generally not difficult since most audio
+filenames have a filename `extension', whilst effect-names do not.
+.SS Special Filenames
+The following special filenames may be used in certain circumstances
+in place of a normal filename on the command line:
+.TP
+\fB\-\fR
+SoX can be used in simple pipeline operations by using the special
+filename `\-' which,
+if used as an input filename, will cause
+SoX will read audio data from `standard input' (stdin),
+and which,
+if used as the output filename, will cause
+SoX will send audio data to `standard output' (stdout).
+Note that when using this option for the output file, and sometimes
+when using it for an input file, the file-type (see
+.B \-t
+below) must also be given.
+.TP
+\fB\(dq\^|\^\fIprogram \fR[\fIoptions\fR] ...\fB\(dq\fR
+This can be used in place of an input filename to specify the
+the given program's standard output (stdout) be used as an input file.
+Unlike
+.B \-
+(above), this can be used for several inputs to one SoX command. For
+example, if `genw' generates mono WAV formatted signals to its
+standard output, then the following command makes a stereo file
+from two generated signals:
+.EX
+ sox \-M "|genw \-\-imd \-" "|genw \-\-thd \-" out.wav
+.EE
+For headerless (raw) audio,
+.B \-t
+(and perhaps other format options) will need to be given, preceding the input
+command.
+.TP
+\fB\(dq\fIwildcard-filename\fB\(dq\fR
+Specifies that filename `globbing' (wild-card matching) should be performed
+by SoX instead of by the shell. This allows a single set of file options to be
+applied to a group of files. For example, if the current directory contains
+three `vox' files, file1.vox, file2.vox, and file3.vox, then
+.EX
+ play \-\-rate 6k *.vox
+.EE
+will be expanded by the `shell' (in most environments) to
+.EX
+ play \-\-rate 6k file1.vox file2.vox file3.vox
+.EE
+which will treat only the first vox file as having a sample rate of 6k.
+With
+.EX
+ play \-\-rate 6k "*.vox"
+.EE
+the given sample rate option will be applied to all three vox files.
+.TP
+\fB\-p\fR, \fB\-\-sox\-pipe\fR
+This can be used in place of an output filename to specify that
+the SoX command should be used as in input pipe to another SoX command.
+For example, the command:
+.EX
+ play "|sox \-n \-p synth 2" "|sox \-n \-p synth 2 tremolo 10" stat
+.EE
+plays two `files' in succession, each with different effects.
+.SP
+.B \-p
+is in fact an alias for `\fB\-t sox \-\fR'.
+.TP
+\fB\-d\fR, \fB\-\-default\-device\fR
+This can be used in place of an input or output filename to specify that
+the default audio device (if one has been built into SoX) is to be used.
+This is akin to invoking
+.B rec
+or
+.B play
+(as described above).
+.TP
+\fB\-n\fR, \fB\-\-null\fR
+This can be used in place of an input or output filename to specify that
+a `null file' is to be used. Note that here, `null file' refers to a
+SoX-specific mechanism and is not related to any operating-system
+mechanism with a similar name.
+.SP
+Using a null file to input audio is equivalent to
+using a normal audio file that contains an infinite amount
+of silence, and as such is not generally useful unless used
+with an effect that specifies a finite time length
+(such as \fBtrim\fR or \fBsynth\fR).
+.SP
+Using a null file to output audio amounts to discarding the audio
+and is useful mainly with effects that produce information about the
+audio instead of affecting it (such as \fBnoiseprof\fR or \fBstat\fR).
+.SP
+The sampling rate associated with a null file
+is by default 48\ kHz, but, as with a normal
+file, this can be overridden if desired using command-line format
+options (see below).
+.SS Supported File & Audio Device Types
+See
+.BR soxformat (7)
+for a list and description of the supported file formats and audio device
+drivers.
+.SH OPTIONS
+.SS Global Options
+These options can be specified on the command line at any point
+before the first effect name.
+.SP
+The
+.B SOX_OPTS
+environment variable can be used to provide alternative default values for
+SoX's global options.
+For example:
+.EX
+ SOX_OPTS="\-\-buffer 20000 \-\-play\-rate\-arg \-hs \-\-temp /mnt/temp"
+.EE
+Note that setting SOX_OPTS can potentially create unwanted changes in
+the behaviour of scripts or other programs that invoke SoX. SOX_OPTS
+might best be used for things (such as in the given example) that reflect the
+environment in which SoX is being run. Enabling options such as
+.B \-\-no\-clobber
+as default might be handled better using a shell alias
+since a shell alias will not affect operation in scripts etc.
+.SP
+One way to ensure that a script cannot be affected by SOX_OPTS is to
+clear SOX_OPTS at the start of the script, but this of course loses
+the benefit of SOX_OPTS carrying some system-wide default options. An
+alternative approach is to explicitly invoke SoX with default
+option values, e.g.
+.EX
+ SOX_OPTS="\-V \-\-no-clobber"
+ ...
+ sox \-V2 \-\-clobber $input $output ...
+.EE
+Note that the way to set environment variables varies from system
+to system. Here are some examples:
+.SP
+Unix bash:
+.EX
+ export SOX_OPTS="\-V \-\-no-clobber"
+.EE
+Unix csh:
+.EX
+ setenv SOX_OPTS "\-V \-\-no-clobber"
+.EE
+MS-DOS/MS-Windows:

+\fB\-\-effects\-file \fIFILENAME\fR
+Use FILENAME to obtain all effects and their arguments.

+\fB\-\-no\-clobber\fR

+\fB\-r, \fB\-\-rate\fR \fIRATE\fR[\fBk\fR]
+Gives the sample rate in Hz (or kHz if appended with `k') of the file.
+.SP
+For an input file, the most common use for this option is to inform
+SoX of the sample rate of a `raw' (`headerless') audio file (see the
+examples in
+.B \-b
+and
+.B \-c
+above).
+Occasionally it may be useful to use this option with a `headered'
+file, in order to override the (presumably incorrect) value in the
+header\*mnote that this is only supported with certain file types.
+For example, if audio was recorded with a sample-rate of say 48k from
+a source that played back a little, say 1\*d5%, too slowly, then
+.EX
+ sox \-r 48720 input.wav output.wav
+.EE
+effectively corrects the speed by changing only the file header (but see
+also the
+.B speed
+effect for the more usual solution to this problem).
+.SP
+For an output file, this option provides a shorthand for specifying
+that the
+.B rate
+effect should be invoked in order to change (if necessary) the sample
+rate of the audio signal to the given value. For example, the
+following two commands are equivalent:
+.EX
+.ne 2
+ sox input.wav \-r 48k output.wav bass \-b 24
+ sox input.wav output.wav bass \-b 24 rate 48k
+.EE
+though the second form is more flexible as it allows
+.B rate
+options to be given, and allows the effects to be ordered arbitrarily.
+.TP
+\fB\-t\fR, \fB\-\-type\fR \fIFILE-TYPE\fR
+Gives the type of the audio file. For both input and output files,
+this option is commonly used to inform SoX of the type a `headerless'
+audio file (e.g. raw, mp3) where the actual/desired type cannot be
+determined from a given filename extension. For example:
+.EX
+ another-command | sox \-t mp3 \- output.wav
+
+ sox input.wav \-t raw output.bin
+.EE
+It can also be used to override the type implied by an input filename
+extension, but if overriding with a type that has a header, SoX will
+exit with an appropriate error message if such a header is not
+actually present.

+\
+These options specify whether the byte-order of the audio data is,

+identifier, or for an output file that is actually an audio device.
+.SP
+.B N.B.
+Unlike other format characteristics, the endianness (byte, nibble, &

+.SH EFFECTS
+In addition to converting, playing and recording audio files, SoX can
+be used to invoke a number of audio `effects'. Multiple effects may
+be applied by specifying them one after another at the end of the SoX
+command line, forming an `effects chain'.
+Note that applying multiple effects in real-time (i.e. when playing audio)
+is likely to require a high performance computer. Stopping other applications
+may alleviate performance issues should they occur.
+.SP
+Some of the SoX effects are primarily intended to be applied to a single
+instrument or `voice'. To facilitate this, the \fBremix\fR effect and
+the global SoX option \fB\-M\fR can be used to isolate then recombine
+tracks from a multi-track recording.
+.SS Multiple Effects Chains
+A single effects chain is made up of one or more effects. Audio from
+the input runs through the chain until either the end of the input file
+is reached or an effect in the chain requests to terminate the chain.
+.SP
+SoX supports running multiple effects chains over the input audio.
+In this case, when one chain indicates it is done processing audio,
+the audio data is then sent through the next effects chain. This
+continues until either no more effects chains exist or the input has
+reached the end of the file.
+.SP
+An effects chain is terminated by placing a
+.B :
+(colon) after an effect. Any following effects are a part of a new effects chain.
+.SP
+It is important to place the effect that will stop the chain
+as the first effect in the chain. This is because any samples
+that are buffered by effects to the left of the terminating effect
+will be discarded. The amount of samples discarded is related to the
+.B \-\-buffer
+option and it should be kept small, relative to the sample rate, if
+the terminating effect cannot be first. Further information on
+stopping effects can be found in the
+.B Stopping SoX
+section.
+.SP
+There are a few pseudo-effects that aid using multiple effects chains.
+These include
+.B newfile
+which will start writing to a new output file before moving to the
+next effects chain and
+.B restart
+which will move back to the first effects chain. Pseudo-effects
+must be specified as the first effect in a chain and as the only
+effect in a chain (they must have a
+.B :
+before and after they are specified).
+.SP
+The following is an example of multiple effects chains. It will split the
+input file into multiple files of 30 seconds in length. Each output filename
+will have unique number in its name as documented in the
+.B Output Files
+section.
+.EX

+.SS Common Notation And Parameters
+In the descriptions that follow,
+brackets [ ] are used to denote parameters that are optional, braces
+{ } to denote those that are both optional and repeatable,
+and angle brackets < > to denote those that are repeatable but not
+optional.
+Where applicable, default values for optional parameters are shown in parenthesis ( ).
+.SP
+The following parameters are used with, and have the same meaning for,
+several effects:
+.TP
+\fIcenter\fR[\fBk\fR]
+See
+.IR frequency .
+.TP
+\fIfrequency\fR[\fBk\fR]
+A frequency in Hz, or, if appended with `k', kHz.
+.TP
+\fIgain\fR
+A power gain in dB.
+Zero gives no gain; less than zero gives an attenuation.
+.TP
+\fIposition\fR
+A position within the audio stream; the syntax is
+[\fB=\fR\^|\^\fB+\fR\^|\^\fB\-\fR]\fItimespec\fR, where \fItimespec\fR is a
+time specification (see below). The optional first character indicates
+whether the \fItimespec\fR is to be interpreted relative to the start
+(\fB=\fR) or end (\fB\-\fR) of audio, or to the previous \fIposition\fR if
+the effect accepts multiple position arguments (\fB+\fR). The audio length
+must be known for end-relative locations to work; some effects do accept
+\fB\-0\fR for end-of-audio, though, even if the length is unknown. Which of
+\fB=\fR, \fB+\fR, \fB\-\fR is the default depends on the effect and is shown
+in its syntax as, e.g., \fIposition(+)\fR.
+.SP
+Examples: \fB=2:00\fR (two minutes into the audio stream), \fB\-100s\fR (one
+hundred samples before the end of audio), \fB+0:12+10s\fR (twelve seconds
+and ten samples after the previous position), \fB\-0.5+1s\fR (one sample less
+than half a second before the end of audio).
+.TP
+\fIwidth\fR[\fBh\fR\^|\^\fBk\fR\^|\^\fBo\fR\^|\^\fBq\fR]
+Used to specify the band-width of a filter. A number of different
+methods to specify the width are available (though not all for every effect).
+One of the characters shown may be appended to select the desired method
+as follows:

+.SP
+For each effect that uses this parameter, the default method (i.e. if no
+character is appended) is the one that it listed first in the first line of
+the effect's description.
+.PP
+Most effects that expect an audio position or duration in a parameter,
+i.e. a \fBtime specification\fR, accept either of the following two forms:
+.TP
+[[\fIhours\fB:\fR]\fIminutes\fB:\fR]\fIseconds\fR[\fB.\fIfrac\fR][\fBt\fR]
+A specification of `1:30\*d5' corresponds to one minute, thirty and
+\(12 seconds. The \fBt\fR suffix is entirely optional (however, see the
+\fBsilence\fR effect for an exception).
+Note that the component values do not have to be normalized; e.g.,
+`1:23:45', `83:45', `79:0285', `1:0:1425', `1::1425' and `5025' all are
+legal and equivalent to each other.
+.TP
+\fIsamples\fBs\fR
+Specifies the number of samples directly, as in `8000s'. For large sample
+counts, \fIe notation\fR is supported: `1.7e6s' is the same as `1700000s'.
+.PP
+Time specifications can also be chained with \fB+\fR or \fB\-\fR into a new
+time specification where the right part is added to or subtracted from the
+left, respectively: `3:00\-200s' means two hundred samples less than three
+minutes.

+The \fB\-n\fR (for noise) option uses the alternate mode
+for un-pitched audio (e.g. percussion).
+.B Warning:
+\fB\-n\fR introduces a power-gain of about 11dB in the filter, so beware

+Boost or cut the bass (lower) or treble (upper) frequencies of the audio
+using a two-pole shelving filter with a response similar to that
+of a standard hi-fi's tone-controls. This is also
+known as shelving equalisation (EQ).
+.SP
+\fIgain\fR gives the gain at 0\ Hz (for \fBbass\fR), or whichever is
+the lower of \(ap22\ kHz and the Nyquist frequency (for \fBtreble\fR). Its
+useful range is about \-20 (for a large cut) to +20 (for a large
+boost).
+Beware of
+.B Clipping
+when using a positive \fIgain\fR.
+.SP
+If desired, the filter can be fine-tuned using the following
+optional parameters:
+.SP
+\fIfrequency\fR sets the filter's central frequency and so can be
+used to extend or reduce the frequency range to be boosted or
+cut. The default value is 100\ Hz (for \fBbass\fR) or 3\ kHz (for
+\fBtreble\fR).
+.SP
+\fIwidth\fR
+determines how
+steep is the filter's shelf transition. In addition to the common
+width specification methods described above,
+`slope' (the default, or if appended with `\fBs\fR') may be used.
+The useful range of `slope' is
+about 0\*d3, for a gentle slope, to 1 (the maximum), for a steep slope; the

+\fBbend\fR [\fB\-f \fIframe-rate\fR(25)] [\fB\-o \fIover-sample\fR(16)] { \fIstart-position(+)\fB,\fIcents\fB,\fIend-position(+)\fR }
+Changes pitch by specified amounts at specified times.
+Each given triple: \fIstart-position\fB,\fIcents\fB,\fIend-position\fR
+specifies one bend.
+\fIcents\fR is the number of cents (100 cents = 1 semitone) by which to
+bend the pitch. The other values specify the points in time at which to start
+and end bending the pitch, respectively.
+.SP
+The pitch-bending algorithm utilises the Discrete Fourier Transform (DFT)
+at a particular frame rate and over-sampling rate.
+The
+.B \-f
+and
+.B \-o
+parameters may be used to adjust these parameters and thus control the
+smoothness of the changes in pitch.
+.SP
+For example, an initial tone is generated, then bent three times, yielding
+four different notes in total:
+.EX
+.ne 2
+ play \-n synth 2.5 sin 667 gain 1 \\
+ bend .35,180,.25 .15,740,.53 0,\-520,.3

+\fBchorus \fIgain-in gain-out\fR <\fIdelay decay speed depth \fB\-s\fR\^|\^\fB\-t\fR>
+Add a chorus effect to the audio. This can make a single vocal sound
+like a chorus, but can also be applied to instrumentation.
+.SP
+Chorus resembles an echo effect with a short delay, but
+whereas with echo the delay is constant, with chorus, it
+is varied using sinusoidal or triangular modulation. The modulation
+depth defines the range the modulated delay is played before or after the
+delay. Hence the delayed sound will sound slower or faster, that is the delayed
+sound tuned around the original one, like in a chorus where some vocals are
+slightly off key.
+See [3] for more discussion of the chorus effect.
+.SP
+Each four-tuple parameter
+delay/decay/speed/depth gives the delay in milliseconds
+and the decay (relative to gain-in) with a modulation
+speed in Hz using depth in milliseconds.
+The modulation is either sinusoidal (\fB\-s\fR) or triangular
+(\fB\-t\fR). Gain-out is the volume of the output.
+.SP
+A typical delay is around 40ms to 60ms; the modulation speed is best
+near 0\*d25Hz and the modulation depth around 2ms.

+.SP
+The

+and

+parameters (in seconds) determine the time over which the
+instantaneous level of the input signal is averaged to determine its
+volume; attacks refer to increases in volume and decays refer to
+decreases.
+For most situations, the attack time (response to the music getting
+louder) should be shorter than the decay time because the human ear is more
+sensitive to sudden loud music than sudden soft music.
+Where more than one pair of attack/decay parameters are
+specified, each input channel is companded separately and the number of
+pairs must agree with the number of input channels.
+Typical values are
+.B 0\*d3,0\*d8
+seconds.
+.SP
+The second parameter is a list of points on the compander's transfer
+function specified in dB relative to the maximum possible signal
+amplitude. The input values must be in a strictly increasing order but
+the transfer function does not have to be monotonically rising. If
+omitted, the value of
+.I out-dB1
+defaults to the same value as
+.IR in-dB1 ;
+levels below
+.I in-dB1
+are not companded (but may have gain applied to them).
+The point \fB0,0\fR is assumed but may be overridden (by
+\fB0,\fIout-dBn\fR).
+If the list is preceded by a
+.I soft-knee-dB
+value, then the points at where adjacent line segments on the
+transfer function meet will be rounded by the amount given.
+Typical values for the transfer function are
+.BR 6:\-70,\-60,\-20 .
+.SP
+The third (optional) parameter is an additional gain in dB to be applied
+at all points on the transfer function and allows easy adjustment
+of the overall gain.
+.SP
+The fourth (optional) parameter is an initial level to be assumed for
+each channel when companding starts. This permits the user to supply a
+nominal level initially, so that, for example, a very large gain is not
+applied to initial signal levels before the companding action has begun
+to operate: it is quite probable that in such an event, the output would
+be severely clipped while the compander gain properly adjusts itself.
+A typical value (for audio which is initially quiet) is
+.B \-90
+dB.
+.SP
+The fifth (optional) parameter is a delay in seconds. The input signal
+is analysed immediately to control the compander, but it is delayed
+before being fed to the volume adjuster. Specifying a delay
+approximately equal to the attack/decay times allows the compander to
+effectively operate in a `predictive' rather than a reactive mode.

+The following example might be used to make a piece of music with both

+such as a moving vehicle:
+.EX
+ sox asz.wav asz-car.wav compand 0.3,1 6:\-70,\-60,\-20 \-5 \-90 0.2
+.EE
+The transfer function (`6:\-70,...') says that very soft sounds (below
+\-70dB) will remain unchanged. This will stop the compander from
+boosting the volume on `silent' passages such as between movements.
+However, sounds in the range \-60dB to 0dB (maximum
+volume) will be boosted so that the 60dB dynamic range of the
+original music will be compressed 3-to-1 into a 20dB range, which is
+wide enough to enjoy the music but narrow enough to get around the
+road noise. The `6:' selects 6dB soft-knee companding.
+The \-5 (dB) output gain is needed to avoid clipping (the number is
+inexact, and was derived by experimentation).
+The \-90 (dB) for the initial volume will work fine for a clip that starts
+with near silence, and the delay of 0\*d2 (seconds) has the effect of causing
+the compander to react a bit more quickly to sudden volume changes.

+In the next example, compand is being used as a noise-gate for when the

+\fBdeemph\fR
+Apply Compact Disc (IEC 60908) de-emphasis (a treble attenuation shelving

+.SP
+Pre-emphasis was applied in the mastering of some CDs issued in the early
+1980s. These included many classical music albums, as well as now
+sought-after issues of albums by The Beatles, Pink Floyd and others.
+Pre-emphasis should be removed at playback time by a de-emphasis
+filter in the playback device. However, not all modern CD players have
+this filter, and very few PC CD drives have it; playing pre-emphasised
+audio without the correct de-emphasis filter results in audio that sounds harsh
+and is far from what its creators intended.
+.SP
+With the
+.B deemph
+effect, it is possible to apply the necessary de-emphasis to audio that
+has been extracted from a pre-emphasised CD, and then either burn the
+de-emphasised audio to a new CD (which will then play correctly on any
+CD player), or simply play the correctly de-emphasised audio files on the
+PC. For example:
+.EX

+.EE
+and then burn track1-deemph.wav to CD, or
+.EX
+ play track1\-deemph.wav
+.EE
+or simply
+.EX
+ play track1.wav deemph
+.EE
+The de-emphasis filter is implemented as a biquad and requires the input
+audio sample rate to be either 44.1kHz or 48kHz. Maximum deviation
+from the ideal response is only 0\*d06dB (up to 20kHz).

+Apply dithering to the audio.
+Dithering deliberately adds a small amount of noise to the signal in
+order to mask audible quantization effects that can occur if the output
+sample size is less than 24 bits. With no options, this effect will
+add triangular (TPDF) white noise. Noise-shaping (only for certain
+sample rates) can be selected with
+.BR \-s .
+With the
+.B \-f
+option, it is possible to select a particular noise-shaping filter from
+the following list: lipshitz, f-weighted, modified-e-weighted,
+improved-e-weighted, gesemann, shibata, low-shibata, high-shibata. Note
+that most filter types are available only with 44100Hz sample rate. The
+filter types are distinguished by the following properties: audibility
+of noise, level of (inaudible, but in some circumstances, otherwise
+problematic) shaped high frequency noise, and processing speed.
+.br
+See http://sox.sourceforge.net/SoX/NoiseShaping for graphs of the different
+noise-shaping curves.
+.SP
+The
+.B \-S
+option selects a slightly `sloped' TPDF, biased towards higher
+frequencies. It can be used at any sampling rate but below \(~~22k,
+plain TPDF is probably better, and above \(~~ 37k, noise-shaping
+(if available) is probably better.
+.SP
+The
+.B \-a
+option enables a mode where dithering (and noise-shaping if applicable)
+are automatically enabled only when needed. The most likely use for
+this is when applying fade in or out to an already dithered file, so
+that the redithering applies only to the faded portions. However, auto
+dithering is not fool-proof, so the fades should be carefully checked
+for any noise modulation; if this occurs, then either re-dither the whole
+file, or use
+.BR trim ,
+.BR fade ,
+and concatencate.

+The

+If the SoX global option

+\fBecho \fIgain-in gain-out\fR <\fIdelay decay\fR>
+Add echoing to the audio.
+Echoes are reflected sound and can occur naturally amongst mountains
+(and sometimes large buildings) when talking or shouting; digital echo
+effects emulate this behaviour and are often used to help fill
+out the sound of a single instrument or vocal. The time difference
+between the original signal and the reflection is the `delay' (time),
+and the loudness of the reflected signal is the `decay'. Multiple echoes
+can have different delays and decays.
+.SP
+Each given
+.I "delay decay"
+pair gives the delay in milliseconds
+and the decay (relative to gain-in) of that echo.
+Gain-out is the volume of the output.

+Each

+Gain-out is the volume of the output.

+Like the echo effect, echos stand for `ECHO in Sequel', that is the first echos
+takes the input, the second the input and the first echos, the third the input

+Note that use of any of
+.BR \-e ,
+.BR \-B ,

+or
+.B \-n
+requires temporary file space to store the audio to be processed, so may

+.SP
+Without other options,
+.I gain-dB
+is used to adjust the signal power level by the given number of dB:
+positive amplifies (beware of Clipping), negative attenuates. With
+other options, the
+.I gain-dB
+amplification or attenuation is (logically) applied after the processing due to those options.
+.SP
+Given the
+.B \-e
+option, the levels of the audio channels of a multi-channel file are `equalised', i.e.
+gain is applied to all channels other than that with the highest peak
+level, such that all channels attain the same peak level
+(but, without also giving
+.BR \-n ,
+the audio is not `normalised').
+.SP
+The
+.B \-B
+(balance) option is similar to

+.B \-B
+might be used to correct stereo imbalance caused by an imperfect record
+turntable cartridge. Note
+that unlike
+.BR \-e ,
+.B \-B
+might cause some clipping.
+.SP
+.B \-b
+is similar to
+.B \-B
+but has clipping protection, i.e. if necessary to prevent clipping
+whilst balancing, attenuation is applied to all channels.
+Note, however, that in conjunction with
+.BR \-n ,
+.B \-B
+and
+.B \-b
+are synonymous.
+.SP
+The
+.B \-r
+option is used in conjunction with a prior invocation of
+.B gain
+with the
+.B \-h
+option\*msee below for details.
+.SP
+The
+.B \-n
+option normalises the audio to 0dB FSD; it is often used in conjunction with a negative
+.I gain-dB
+to the effect that the audio is normalised to a given level below 0dB.
+For example,
+.EX
+ sox infile outfile gain \-n
+.EE
+normalises to 0dB, and
+.EX
+ sox infile outfile gain \-n \-3
+.EE
+normalises to \-3dB.
+.SP
+The
+.B \-l
+option invokes a simple limiter, e.g.
+.EX
+ sox infile outfile gain \-l 6
+.EE
+will apply 6dB of gain but never clip. Note that limiting more than a
+few dBs more than occasionally (in a piece of audio) is not recommended
+as it can cause audible distortion.
+See the
+.B compand
+effect for a more capable limiter.
+.SP
+The
+.B \-h
+option is used to apply gain to provide head-room for subsequent
+processing. For example, with
+.EX
+ sox infile outfile gain \-h bass +6
+.EE
+6dB of attenuation will be applied prior to the bass boosting effect
+thus ensuring that it will not clip. Of course, with bass, it is
+obvious how much headroom will be needed, but with other effects (e.g.
+rate, dither) it is not always as clear. Another advantage of using
+\fBgain \-h\fR rather than an explicit attenuation, is that if the
+headroom is not used by subsequent effects, it can be reclaimed with
+\fBgain \-r\fR, for example:
+.EX
+ sox infile outfile gain \-h bass +6 rate 44100 gain \-r
+.EE
+The above effects chain guarantees never to clip nor amplify;
+it attenuates if necessary to prevent clipping, but by only as
+much as is needed to do so.
+.SP
+Output formatting (dithering and bit-depth reduction) also requires
+headroom (which cannot be `reclaimed'), e.g.
+.EX
+ sox infile outfile gain \-h bass +6 rate 44100 gain \-rh dither
+.EE
+Here, the second
+.B gain
+invocation, reclaims as much of the headroom as it can from the

+The simple quality selection described above provides settings that

+Occasionally, however, it may be desirable to fine-tune the resampler's
+filter response; this can be achieved using
+.IR override\ options ,
+as detailed in the following table:
+.ne 6
+.TS

+N.B. Override options cannot be used with the `quick' or `low'
+quality algorithms.
+.SP
+All resamplers use filters that can sometimes create `echo' (a.k.a.
+`ringing') artefacts with transient signals such as those that occur
+with `finger snaps' or other highly percussive sounds. Such artefacts are
+much more noticeable to the human ear if they occur before the transient
+(`pre-echo') than if they occur after it (`post-echo'). Note that
+frequency of any such artefacts is related to the smaller of the
+original and new sampling rates but that if this is at least 44\*d1kHz,
+then the artefacts will lie outside the range of human hearing.
+.SP
+A phase response setting may be used to control the distribution of any
+transient echo between
+`pre' and `post': with minimum phase, there is no pre-echo but the
+longest post-echo; with linear phase, pre and post echo are in equal
+amounts (in signal terms, but not audibility terms); the intermediate
+phase setting attempts to find the best compromise by selecting a small
+length (and level) of pre-echo and a medium lengthed post-echo.
+.SP
+Minimum, intermediate, or linear phase response is selected using the
+.BR \-M ,
+.BR \-I ,
+or
+.B \-L
+option; a custom phase response can be created with the
+.B \-p
+option. Note that phase responses between `linear' and `maximum'
+(greater than 50) are rarely useful.
+.SP
+A resampler's band-width setting determines how much of the frequency
+content of the original signal (w.r.t. the original sample rate when
+up-sampling, or the new sample rate when down-sampling) is preserved
+during conversion. The term `pass-band' is used to refer to all frequencies
+up to the band-width point (e.g. for 44\*d1kHz sampling rate, and a
+resampling band-width of 95%, the pass-band represents frequencies from
+0Hz (D.C.) to circa 21kHz). Increasing the resampler's band-width
+results in a slower conversion and can increase transient echo
+artefacts (and vice versa).
+.SP
+The
+.B \-s
+`steep filter' option changes resampling band-width from the default 95%
+(based on the 3dB point), to 99%. The
+.B \-b
+option allows the band-width to be set to any value in the range
+74\-99\*d7 %, but note that band-width values greater than 99% are not
+recommended for normal use as they can cause excessive transient echo.
+.SP
+If the
+.B \-a
+option is given, then aliasing/imaging above the pass-band is allowed. For
+example, with 44\*d1kHz sampling rate, and a
+resampling band-width of 95%, this means that frequency content above
+21kHz can be distorted; however, since this is above the pass-band (i.e.
+above the highest frequency of interest/audibility), this may not be a
+problem. The benefits of allowing aliasing/imaging are reduced processing time,
+and reduced (by almost half) transient echo artefacts.
+Note that if this option is given, then
+the minimum band-width allowable with
+.B \-b
+increases to 85%.

+Removes silence from the beginning, middle, or end of the audio.
+`Silence' is determined by a specified threshold.
+.SP
+The \fIabove-periods\fR value is used to indicate if audio should be
+trimmed at the beginning of the audio. A value of zero indicates no
+silence should be trimmed from the beginning. When specifying a
+non-zero \fIabove-periods\fR, it trims audio up until it finds
+non-silence. Normally, when trimming silence from beginning of audio
+the \fIabove-periods\fR will be 1 but it can be increased to higher
+values to trim all audio up to a specific count of non-silence
+periods. For example, if you had an audio file with two songs that
+each contained 2 seconds of silence before the song, you could specify
+an \fIabove-period\fR of 2 to strip out both silence periods and the
+first song.
+.SP
+When \fIabove-periods\fR is non-zero, you must also specify a
+\fIduration\fR and \fIthreshold\fR. \fIduration\fR indicates the
+amount of time that non-silence must be detected before it stops
+trimming audio. By increasing the duration, burst of noise can be
+treated as silence and trimmed off.
+.SP
+\fIthreshold\fR is used to indicate what sample value you should treat as
+silence. For digital audio, a value of 0 may be fine but for audio
+recorded from analog, you may wish to increase the value to account
+for background noise.
+.SP
+When optionally trimming silence from the end of the audio, you specify
+a \fIbelow-periods\fR count. In this case, \fIbelow-period\fR means
+to remove all audio after silence is detected.
+Normally, this will be a value 1 of but it can
+be increased to skip over periods of silence that are wanted. For example,
+if you have a song with 2 seconds of silence in the middle and 2 second
+at the end, you could set below-period to a value of 2 to skip over the
+silence in the middle of the audio.
+.SP
+For \fIbelow-periods\fR, \fIduration\fR specifies a period of silence
+that must exist before audio is not copied any more. By specifying
+a higher duration, silence that is wanted can be left in the audio.
+For example, if you have a song with an expected 1 second of silence
+in the middle and 2 seconds of silence at the end, a duration of 2
+seconds could be used to skip over the middle silence.
+.SP
+Unfortunately, you must know the length of the silence at the
+end of your audio file to trim off silence reliably. A workaround is
+to use the \fBsilence\fR effect in combination with the \fBreverse\fR effect.
+By first reversing the audio, you can use the \fIabove-periods\fR
+to reliably trim all audio from what looks like the front of the file.
+Then reverse the file again to get back to normal.
+.SP
+To remove silence from the middle of a file, specify a
+\fIbelow-periods\fR that is negative. This value is then
+treated as a positive value and is also used to indicate that the
+effect should restart processing as specified by the
+\fIabove-periods\fR, making it suitable for removing periods of
+silence in the middle of the audio.
+.SP
+The option
+.B \-l
+indicates that \fIbelow-periods\fR \fIduration\fR length of audio
+should be left intact at the beginning of each period of silence.
+For example, if you want to remove long pauses between words
+but do not want to remove the pauses completely.
+.SP
+\fIduration\fR is a time specification with the peculiarity that a bare
+number is interpreted as a sample count, not as a number of seconds.
+For specifying seconds, either use the \fBt\fR suffix (as in `2t') or
+specify minutes, too (as in `0:02').

+\fIthreshold\fR numbers may be suffixed with

+.I Options:
+.RS
+.IP \fB\-x\ \fInum\fR
+Change the (maximum) width (X-axis) of the spectrogram from its default
+value of 800 pixels to a given number between 100 and 200000.
+See also \fB\-X\fR and \fB\-d\fR.
+.IP \fB\-X\ \fInum\fR
+X-axis pixels/second; the default is auto-calculated to fit the given
+or known audio duration to the X-axis size, or 100 otherwise. If
+given in conjunction with \fB\-d\fR, this option affects the width of
+the spectrogram; otherwise, it affects the duration of the
+spectrogram.
+.I num
+can be from 1 (low time resolution) to 5000 (high time resolution)
+and need not be an integer. SoX
+may make a slight adjustment to the given number for processing
+quantisation reasons; if so, SoX will report the actual number used
+(viewable when the SoX global option
+.B \-V
+is in effect).
+See also \fB\-x\fR and \fB\-d\fR.
+.IP \fB\-y\ \fInum\fR
+Sets the Y-axis size in pixels (per channel); this is the number of
+frequency `bins' used in the Fourier analysis that produces the
+spectrogram. N.B. it can be slow to produce the spectrogram if this
+number is not one more than a power of two (e.g. 129). By default the
+Y-axis size is chosen automatically (depending on the number of
+channels). See
+.B \-Y
+for alternative way of setting spectrogram height.
+.IP \fB\-Y\ \fInum\fR
+Sets the target total height of the spectrogram(s). The default value
+is 550 pixels. Using this option (and by default), SoX will choose a
+height for individual spectrogram channels that is one more than a
+power of two, so the actual total height may fall short of the given
+number. However, there is also a minimum height per channel so if
+there are many channels, the number may be exceeded.
+See
+.B \-y
+for alternative way of setting spectrogram height.
+.IP \fB\-z\ \fInum\fR
+Z-axis (colour) range in dB, default 120. This sets the dynamic-range
+of the spectrogram to be \-\fInum\fR\ dBFS to 0\ dBFS.
+.I Num
+may range from 20 to 180. Decreasing dynamic-range effectively
+increases the `contrast' of the spectrogram display, and vice versa.
+.IP \fB\-Z\ \fInum\fR
+Sets the upper limit of the Z-axis in dBFS.
+A negative
+.I num
+effectively increases the `brightness' of the spectrogram display,
+and vice versa.
+.IP \fB\-q\ \fInum\fR
+Sets the Z-axis quantisation, i.e. the number of different colours (or
+intensities) in which to render Z-axis
+values. A small number (e.g. 4) will give a `poster'-like effect making
+it easier to discern magnitude bands of similar level. Small numbers
+also usually
+result in small PNG files. The number given specifies the number of
+colours to use inside the Z-axis range; two colours are reserved to
+represent out-of-range values.
+.IP \fB\-w\ \fIname\fR
+Window: Hann (default), Hamming, Bartlett, Rectangular, Kaiser or Dolph. The
+spectrogram is produced using the Discrete Fourier Transform (DFT)
+algorithm. A significant parameter to this algorithm is the choice of
+`window function'. By default, SoX uses the Hann window which has good
+all-round frequency-resolution and dynamic-range properties. For better
+frequency resolution (but lower dynamic-range), select a Hamming window;
+for higher dynamic-range (but poorer frequency-resolution), select a
+Dolph window. Kaiser, Bartlett and Rectangular windows are also available.
+.IP \fB\-W\ \fInum\fR
+Window adjustment parameter. This can be used to make small
+adjustments to the Kaiser or Dolph window shape. A positive number (up to
+ten) increases its dynamic range, a negative number decreases it.
+.IP \fB\-s\fR
+Allow slack overlapping of DFT windows.
+This can, in some cases, increase image sharpness and give greater adherence
+to the
+.B \-x
+value, but at the expense of a little spectral loss.
+.IP \fB\-m\fR
+Creates a monochrome spectrogram (the default is colour).
+.IP \fB\-h\fR
+Selects a high-colour palette\*mless visually pleasing than the default
+colour palette, but it may make it easier to differentiate different levels.
+If this option is used in conjunction with
+.BR \-m ,
+the result will be a hybrid monochrome/colour palette.
+.IP \fB\-p\ \fInum\fR
+Permute the colours in a colour or hybrid palette.
+The
+.I num
+parameter, from 1 (the default) to 6, selects the permutation.
+.IP \fB\-l\fR
+Creates a `printer friendly' spectrogram with a light background (the
+default has a dark background).
+.IP \fB\-a\fR
+Suppress the display of the axis lines. This is sometimes useful in
+helping to discern artefacts at the spectrogram edges.
+.IP \fB\-r\fR
+Raw spectrogram: suppress the display of axes and legends.
+.IP \fB\-A\fR
+Selects an alternative, fixed colour-set. This is provided only for
+compatibility with spectrograms produced by another package. It should
+not normally be used as it has some problems, not least, a lack of
+differentiation at the bottom end which results in masking of low-level
+artefacts.
+.IP \fB\-t\ \fItext\fR
+Set the image title\*mtext to display above the spectrogram.
+.IP \fB\-c\ \fItext\fR
+Set (or clear) the image comment\*mtext to display below and to the

+\fBspeed \fIfactor\fR[\fBc\fR]
+Adjust the audio speed (pitch and tempo together). \fIfactor\fR
+is either the ratio of the new speed to the old speed: greater
+than 1 speeds up, less than 1 slows down, or, if appended with the
+letter
+`c', the number of cents (i.e. 100ths of a semitone) by
+which the pitch (and tempo) should be adjusted: greater than 0
+increases, less than 0 decreases.

+Technically, the speed effect only changes the sample rate information,
+leaving the samples themselves untouched. The \fBrate\fR effect is invoked
+automatically to resample to the output sample rate, using its default

+beginning of the audio section to splice on should be trimmed with the
+same
+.IR excess
+(before the ideal joining point), plus an additional
+.I leeway
+(default 0\*d005 seconds). Any time specification may be used for these

+effect given with the position at which to perform the splice\*mthis is

+ play "|sox \-n \-p synth 1 sin %1" "|sox \-n \-p synth 1 sin %3"

+generates and plays two notes, but there is a nasty click at the

+It is also possible to use this effect to perform general cross-fades,

+`middle A' (440\ Hz). For example, the following could be used to
+help tune a guitar's low `E' string:
+.EX
+ play \-n synth 4 pluck %\-29
+.EE
+or with a (Bourne shell) loop, the whole guitar:
+.EX
+.ne 2
+ for n in E2 A2 D3 G3 B3 E4; do
+ play \-n synth 4 pluck $n repeat 2; done
+.EE
+See the
+.B delay
+effect (above) and the reference to `SoX scripting examples' (below)
+for more
+.B synth
+examples.
+.SP
+.B N.B.
+This effect generates audio at maximum volume (0dBFS), which means that there
+is a high chance of clipping when using the audio subsequently, so
+in many cases, you will want to follow this effect with the \fBgain\fR
+effect to prevent this from happening. (See also
+.B Clipping
+above.)
+Note that, by default, the
+.B synth
+effect incorporates the functionality of \fBgain \-h\fR (see the
+.B gain
+effect for details);
+.BR synth 's
+.B \-n
+option may be given to disable this behaviour.
+.SP
+A detailed description of each
+.B synth
+parameter follows:
+.SP
+\fIlen\fR is the length of audio to synthesise (any time specification);
+a value of 0 indicated to use the input length, which is also the default.
+.SP
+\fItype\fR is one of sine, square, triangle, sawtooth, trapezium, exp,
+[white]noise, tpdfnoise, pinknoise, brownnoise, pluck; default=sine.
+.SP
+\fIcombine\fR is one of create, mix, amod (amplitude modulation), fmod
+(frequency modulation); default=create.
+.SP
+\fIfreq\fR/\fIfreq2\fR are the frequencies at the beginning/end of
+synthesis in Hz or, if preceded with `%', semitones relative to A
+(440\ Hz); alternatively, `scientific' note notation (e.g. E2) may
+be used. The default frequency is 440Hz. By default, the tuning used
+with the note notations is `equal temperament'; the
+.B \-j
+.I KEY
+option selects `just intonation', where
+.I KEY
+is an integer number of semitones relative to A (so for example, \-9
+or 3 selects the key of C), or a note in scientific notation.
+.SP
+If
+.I freq2
+is given, then
+.I len
+must also have been given and the generated tone will be swept between
+the given frequencies. The two given frequencies must be separated by
+one of the characters `:', `+', `/', or `\-'. This character is used to
+specify the sweep function as follows:
+.RS
+.IP \fB:\fR
+Linear: the tone will change by a fixed number of hertz per second.
+.IP \fB+\fR
+Square: a second-order function is used to change the tone.
+.IP \fB/\fR
+Exponential: the tone will change by a fixed number of semitones per second.
+.IP \fB\-\fR
+Exponential: as `/', but initial phase always zero, and stepped (less
+smooth) frequency changes.
+.RE
+.TP
+\
+Not used for noise.
+.SP
+\fIoff\fR is the bias (DC-offset) of the signal in percent; default=0.
+.SP
+\fIph\fR is the phase shift in percentage of 1 cycle; default=0. Not
+used for noise.
+.SP
+\fIp1\fR is the percentage of each cycle that is `on' (square), or
+`rising' (triangle, exp, trapezium); default=50 (square, triangle, exp),
+default=10 (trapezium), or sustain (pluck); default=40.
+.SP
+\fIp2\fR (trapezium): the percentage through each cycle at which `falling'
+begins; default=50. exp: the amplitude in multiples of 2dB; default=50,
+or tone-1 (pluck); default=20.
+.SP
+\fIp3\fR (trapezium): the percentage through each cycle at which `falling'
+ends; default=60, or tone-2 (pluck); default=90.
+.TP
+\fBtempo \fR[\fB\-q\fR] [\fB\-m\fR\^|\^\fB\-s\fR\^|\^\fB\-l\fR] \fIfactor\fR [\fIsegment\fR [\fIsearch\fR [\fIoverlap\fR]]]
+Change the audio playback speed but not its pitch. This effect uses the
+WSOLA algorithm. The audio is chopped up into segments which are then
+shifted in the time domain and overlapped (cross-faded) at points where
+their waveforms are most similar as determined by measurement of `least
+squares'.
+.SP
+By default, linear searches are used to find the best overlapping
+points. If the optional
+.B \-q
+parameter is given, tree searches are used instead. This makes the effect
+work more quickly, but the result may not sound as good. However, if you
+must improve the processing speed, this generally reduces the sound quality
+less than reducing the search or overlap values.
+.SP
+The
+.B \-m
+option is used to optimize default values of segment, search and
+overlap for music processing.
+.SP
+The
+.B \-s
+option is used to optimize default values of segment, search and
+overlap for speech processing.
+.SP
+The
+.B \-l
+option is used to optimize default values of segment, search and
+overlap for `linear' processing that tends to cause more
+noticeable distortion but may be useful when factor is close to 1.
+.SP
+If \-m, \-s, or \-l is specified, the default value of segment will be
+calculated based on factor, while default search and overlap values are
+based on segment. Any values you provide still override these default
+values.
+.SP
+.I factor
+gives the ratio of new tempo to the old tempo, so e.g. 1.1 speeds up the
+tempo by 10%, and 0.9 slows it down by 10%.
+.SP
+The optional
+.I segment
+parameter selects the algorithm's segment size in milliseconds. If no other
+flags are specified, the default value is 82 and is typically suited to
+making small changes to the tempo of music. For larger changes (e.g. a factor
+of 2), 41\ ms may give a better result. The \-m, \-s, and \-l flags will cause
+the segment default to be automatically adjusted based on factor.
+For example using \-s (for speech) with a tempo of 1.25 will calculate a
+default segment value of 32.
+.SP
+The optional
+.I search
+parameter gives the audio length in milliseconds over which
+the algorithm will search for overlapping points. If no other
+flags are specified, the default value is 14.68. Larger values use
+more processing time and may or may not produce better results.
+A practical maximum is half the value of segment. Search
+can be reduced to cut processing time at the risk of degrading output
+quality. The \-m, \-s, and \-l flags will cause
+the search default to be automatically adjusted based on segment.
+.SP
+The optional
+.I overlap
+parameter gives the segment overlap length in milliseconds.
+Default value is 12, but \-m, \-s, or \-l flags automatically
+adjust overlap based on segment size. Increasing overlap increases
+processing time and may increase quality. A practical maximum for overlap
+is the value of search, with overlap typically being (at least) a little
+smaller then search.
+.SP

+Apply a treble tone-control effect.
+See the description of the \fBbass\fR effect for details.
+.TP
+\fBtremolo \fIspeed\fR [\fIdepth\fR]
+Apply a tremolo (low frequency amplitude modulation) effect to the audio.
+The tremolo frequency in Hz is given by
+.IR speed ,
+and the depth as a percentage by
+.I depth
+(default 40).
+.TP
+\fBtrim\fR {\fIposition(+)\fR}
+Cuts portions out of the audio. Any number of \fIposition\fRs may be
+given; audio is not sent to the output until the first \fIposition\fR
+is reached. The effect then alternates between copying and discarding
+audio at each \fIposition\fR. Using a value of 0 for the first \fIposition\fR
+parameter allows copying from the beginning of the audio.
+.SP
+For example,
+.EX
+ sox infile outfile trim 0 10
+.EE
+will copy the first ten seconds, while
+.EX
+ play infile trim 12:34 =15:00 -2:00
+.EE
+and
+.EX
+ play infile trim 12:34 2:26 -2:00
+.EE
+will both play from 12 minutes 34 seconds into the audio up to 15 minutes into
+the audio (i.e. 2 minutes and 26 seconds long), then resume playing two
+minutes before the end of audio.
+.TP
+\fBupsample\fR [\fIfactor\fR]
+Upsample the signal by an integer factor: \fIfactor\fR\-1 zero-value
+samples are inserted between each pair of input samples. As a result, the
+original spectrum is replicated into the new frequency space (imaging) and
+attenuated. This attenuation can be compensated for by adding
+\fBvol \fIfactor\fR after any further processing. The upsample effect is
+typically used in combination with filtering effects.
+.SP
+For a general resampling effect with anti-imaging, see \fBrate\fR. See
+also \fBdownsample\fR.
+.TP
+\fBvad \fR[\fIoptions\fR]
+Voice Activity Detector. Attempts to trim silence and quiet
+background sounds from the ends of (fairly high resolution
+i.e. 16-bit, 44\-48kHz) recordings of speech. The algorithm currently
+uses a simple cepstral power measurement to detect voice, so may be
+fooled by other things, especially music. The effect can trim only
+from the front of the audio, so in order to trim from the back, the
+.B reverse
+effect must also be used. E.g.
+.EX
+ play speech.wav norm vad
+.EE
+to trim from the front,
+.EX
+ play speech.wav norm reverse vad reverse
+.EE
+to trim from the back, and
+.EX
+ play speech.wav norm vad reverse vad reverse
+.EE
+to trim from both ends. The use of the
+.B norm
+effect is recommended, but remember that neither

+\fBvol \fIgain\fR [\fItype\fR [\fIlimitergain\fR]]
+Apply an amplification or an attenuation to the audio signal.
+Unlike the

+SoX effects processing chain),
+.B vol
+is an effect like any other so can be applied anywhere, and several times

+The

+An optional \fIlimitergain\fR value can be specified and should be a
+value much less
+than 1 (e.g. 0\*d05 or 0\*d02) and is used only on peaks to prevent clipping.

+DESCRIPTION
+ Introduction
+ SoX reads and writes audio files in most popular formats and can
+ optionally apply effects to them. It can combine multiple input
+ sources, synthesise audio, and, on many systems, act as a general pur‐
+ pose audio player or a multi-track audio recorder. It also has limited
+ ability to split the input into multiple output files.
+
+ All SoX functionality is available using just the sox command. To sim‐
+ plify playing and recording audio, if SoX is invoked as play, the out‐
+ put file is automatically set to be the default sound device, and if
+ invoked as rec, the default sound device is used as an input source.
+ Additionally, the soxi(1) command provides a convenient way to just
+ query audio file header information.
+
+ The heart of SoX is a library called libSoX. Those interested in
+ extending SoX or using it in other programs should refer to the libSoX
+ manual page: libsox(3).
+
+ SoX is a command-line audio processing tool, particularly suited to
+ making quick, simple edits and to batch processing. If you need an
+ interactive, graphical audio editor, use audacity(1).
+
+ * * *
+
+ The overall SoX processing chain can be summarised as follows:
+
+ Input(s) → Combiner → Effects → Output(s)
+
+ Note however, that on the SoX command line, the positions of the Out‐
+ put(s) and the Effects are swapped w.r.t. the logical flow just shown.
+ Note also that whilst options pertaining to files are placed before
+ their respective file name, the opposite is true for effects. To show
+ how this works in practice, here is a selection of examples of how SoX
+ might be used. The simple
+ sox recital.au recital.wav
+ translates an audio file in Sun AU format to a Microsoft WAV file,
+ whilst
+ sox recital.au -b 16 recital.wav channels 1 rate 16k fade 3 norm
+ performs the same format translation, but also applies four effects
+ (down-mix to one channel, sample rate change, fade-in, nomalize), and
+ stores the result at a bit-depth of 16.
+ sox -r 16k -e signed -b 8 -c 1 voice-memo.raw voice-memo.wav
+ converts `raw' (a.k.a. `headerless') audio to a self-describing file
+ format,
+ sox slow.aiff fixed.aiff speed 1.027
+ adjusts audio speed,
+ sox short.wav long.wav longer.wav
+ concatenates two audio files, and
+ sox -m music.mp3 voice.wav mixed.flac
+ mixes together two audio files.
+ play "The Moonbeams/Greatest/*.ogg" bass +3
+ plays a collection of audio files whilst applying a bass boosting
+ effect,
+ play -n -c1 synth sin %-12 sin %-9 sin %-5 sin %-2 fade h 0.1 1 0.1
+ plays a synthesised `A minor seventh' chord with a pipe-organ sound,
+ rec -c 2 radio.aiff trim 0 30:00
+ records half an hour of stereo audio, and
+ play -q take1.aiff & rec -M take1.aiff take1-dub.aiff
+ (with POSIX shell and where supported by hardware) records a new track
+ in a multi-track recording. Finally,
+ rec -r 44100 -b 16 -e signed-integer -p \
+ silence 1 0.50 0.1% 1 10:00 0.1% | \
+ sox -p song.ogg silence 1 0.50 0.1% 1 2.0 0.1% : \
+ newfile : restart
+ records a stream of audio such as LP/cassette and splits in to multiple
+ audio files at points with 2 seconds of silence. Also, it does not
+ start recording until it detects audio is playing and stops after it
+ sees 10 minutes of silence.
+
+ N.B. The above is just an overview of SoX's capabilities; detailed
+ explanations of how to use all SoX parameters, file formats, and
+ effects can be found below in this manual, in soxformat(7), and in
+ soxi(1).
+
+ File Format Types
+ SoX can work with `self-describing' and `raw' audio files. `self-
+ describing' formats (e.g. WAV, FLAC, MP3) have a header that completely
+ describes the signal and encoding attributes of the audio data that
+ follows. `raw' or `headerless' formats do not contain this information,
+ so the audio characteristics of these must be described on the SoX com‐
+ mand line or inferred from those of the input file.
+
+ The following four characteristics are used to describe the format of
+ audio data such that it can be processed with SoX:
+
+ sample rate
+ The sample rate in samples per second (`Hertz' or `Hz'). Digi‐
+ tal telephony traditionally uses a sample rate of 8000 Hz
+ (8 kHz), though these days, 16 and even 32 kHz are becoming more
+ common. Audio Compact Discs use 44100 Hz (44.1 kHz). Digital
+ Audio Tape and many computer systems use 48 kHz. Professional
+ audio systems often use 96 kHz.
+
+ sample size
+ The number of bits used to store each sample. Today, 16-bit is
+ commonly used. 8-bit was popular in the early days of computer
+ audio. 24-bit is used in the professional audio arena. Other
+ sizes are also used.
+
+ data encoding
+ The way in which each audio sample is represented (or
+ `encoded'). Some encodings have variants with different byte-
+ orderings or bit-orderings. Some compress the audio data so
+ that the stored audio data takes up less space (i.e. disk space
+ or transmission bandwidth) than the other format parameters and
+ the number of samples would imply. Commonly-used encoding types
+ include floating-point, μ-law, ADPCM, signed-integer PCM, MP3,
+ and FLAC.
+
+ channels
+ The number of audio channels contained in the file. One
+ (`mono') and two (`stereo') are widely used. `Surround sound'
+ audio typically contains six or more channels.
+
+ The term `bit-rate' is a measure of the amount of storage occupied by
+ an encoded audio signal over a unit of time. It can depend on all of
+ the above and is typically denoted as a number of kilo-bits per second
+ (kbps). An A-law telephony signal has a bit-rate of 64 kbps.
+ MP3-encoded stereo music typically has a bit-rate of 128-196 kbps.
+ FLAC-encoded stereo music typically has a bit-rate of 550-760 kbps.
+
+ Most self-describing formats also allow textual `comments' to be embed‐
+ ded in the file that can be used to describe the audio in some way,
+ e.g. for music, the title, the author, etc.
+
+ One important use of audio file comments is to convey `Replay Gain'
+ information. SoX supports applying Replay Gain information (for cer‐
+ tain input file formats only; currently, at least FLAC and Ogg Vorbis),
+ but not generating it. Note that by default, SoX copies input file
+ comments to output files that support comments, so output files may
+ contain Replay Gain information if some was present in the input file.
+ In this case, if anything other than a simple format conversion was
+ performed then the output file Replay Gain information is likely to be
+ incorrect and so should be recalculated using a tool that supports this
+ (not SoX).
+
+ The soxi(1) command can be used to display information from audio file
+ headers.
+
+ Determining & Setting The File Format
+ There are several mechanisms available for SoX to use to determine or
+ set the format characteristics of an audio file. Depending on the cir‐
+ cumstances, individual characteristics may be determined or set using
+ different mechanisms.
+
+ To determine the format of an input file, SoX will use, in order of
+ precedence and as given or available:
+
+ 1. Command-line format options.
+
+ 2. The contents of the file header.
+
+ 3. The filename extension.
+
+ To set the output file format, SoX will use, in order of precedence and
+ as given or available:
+
+ 1. Command-line format options.
+
+ 2. The filename extension.
+
+ 3. The input file format characteristics, or the closest that is sup‐
+ ported by the output file type.
+
+ For all files, SoX will exit with an error if the file type cannot be
+ determined. Command-line format options may need to be added or changed
+ to resolve the problem.
+
+ Playing & Recording Audio
+ The play and rec commands are provided so that basic playing and
+ recording is as simple as
+ play existing-file.wav
+ and
+ rec new-file.wav
+ These two commands are functionally equivalent to
+ sox existing-file.wav -d
+ and
+ sox -d new-file.wav
+ Of course, further options and effects (as described below) can be
+ added to the commands in either form.
+
+ * * *
+
+ Some systems provide more than one type of (SoX-compatible) audio
+ driver, e.g. ALSA & OSS, or SUNAU & AO. Systems can also have more
+ than one audio device (a.k.a. `sound card'). If more than one audio
+ driver has been built-in to SoX, and the default selected by SoX when
+ recording or playing is not the one that is wanted, then the AUDIO‐
+ DRIVER environment variable can be used to override the default. For
+ example (on many systems):
+ set AUDIODRIVER=oss
+ play ...
+ The AUDIODEV environment variable can be used to override the default
+ audio device, e.g.
+ set AUDIODEV=/dev/dsp2
+ play ...
+ sox ... -t oss
+ or
+ set AUDIODEV=hw:soundwave,1,2
+ play ...
+ sox ... -t alsa
+ Note that the way of setting environment variables varies from system
+ to system - for some specific examples, see `SOX_OPTS' below.
+
+ When playing a file with a sample rate that is not supported by the
+ audio output device, SoX will automatically invoke the rate effect to
+ perform the necessary sample rate conversion. For compatibility with
+ old hardware, the default rate quality level is set to `low'. This can
+ be changed by explicitly specifying the rate effect with a different
+ quality level, e.g.
+ play ... rate -m
+ or by using the --play-rate-arg option (see below).
+
+ * * *
+
+ On some systems, SoX allows audio playback volume to be adjusted whilst
+ using play. Where supported, this is achieved by tapping the `v' & `V'
+ keys during playback.
+
+ To help with setting a suitable recording level, SoX includes a peak-
+ level meter which can be invoked (before making the actual recording)
+ as follows:
+ rec -n
+ The recording level should be adjusted (using the system-provided mixer
+ program, not SoX) so that the meter is at most occasionally full scale,
+ and never `in the red' (an exclamation mark is shown). See also -S
+ below.
+
+ Accuracy
+ Many file formats that compress audio discard some of the audio signal
+ information whilst doing so. Converting to such a format and then con‐
+ verting back again will not produce an exact copy of the original
+ audio. This is the case for many formats used in telephony (e.g. A-
+ law, GSM) where low signal bandwidth is more important than high audio
+ fidelity, and for many formats used in portable music players (e.g.
+ MP3, Vorbis) where adequate fidelity can be retained even with the
+ large compression ratios that are needed to make portable players prac‐
+ tical.
+
+ Formats that discard audio signal information are called `lossy'. For‐
+ mats that do not are called `lossless'. The term `quality' is used as
+ a measure of how closely the original audio signal can be reproduced
+ when using a lossy format.
+
+ Audio file conversion with SoX is lossless when it can be, i.e. when
+ not using lossy compression, when not reducing the sampling rate or
+ number of channels, and when the number of bits used in the destination
+ format is not less than in the source format. E.g. converting from an
+ 8-bit PCM format to a 16-bit PCM format is lossless but converting from
+ an 8-bit PCM format to (8-bit) A-law isn't.
+
+ N.B. SoX converts all audio files to an internal uncompressed format
+ before performing any audio processing. This means that manipulating a
+ file that is stored in a lossy format can cause further losses in audio
+ fidelity. E.g. with
+ sox long.mp3 short.mp3 trim 10
+ SoX first decompresses the input MP3 file, then applies the trim
+ effect, and finally creates the output MP3 file by re-compressing the
+ audio - with a possible reduction in fidelity above that which occurred
+ when the input file was created. Hence, if what is ultimately desired
+ is lossily compressed audio, it is highly recommended to perform all
+ audio processing using lossless file formats and then convert to the
+ lossy format only at the final stage.
+
+ N.B. Applying multiple effects with a single SoX invocation will, in
+ general, produce more accurate results than those produced using multi‐
+ ple SoX invocations.
+
+ Dithering
+ Dithering is a technique used to maximise the dynamic range of audio
+ stored at a particular bit-depth. Any distortion introduced by quanti‐
+ sation is decorrelated by adding a small amount of white noise to the
+ signal. In most cases, SoX can determine whether the selected process‐
+ ing requires dither and will add it during output formatting if appro‐
+ priate.
+
+ Specifically, by default, SoX automatically adds TPDF dither when the
+ output bit-depth is less than 24 and any of the following are true:
+
+ · bit-depth reduction has been specified explicitly using a command-
+ line option
+
+ · the output file format supports only bit-depths lower than that of
+ the input file format
+
+ · an effect has increased effective bit-depth within the internal
+ processing chain
+
+ For example, adjusting volume with vol 0.25 requires two additional
+ bits in which to losslessly store its results (since 0.25 decimal
+ equals 0.01 binary). So if the input file bit-depth is 16, then SoX's
+ internal representation will utilise 18 bits after processing this vol‐
+ ume change. In order to store the output at the same depth as the
+ input, dithering is used to remove the additional bits.
+
+ Use the -V option to see what processing SoX has automatically added.
+ The -D option may be given to override automatic dithering. To invoke
+ dithering manually (e.g. to select a noise-shaping curve), see the
+ dither effect.
+
+ Clipping
+ Clipping is distortion that occurs when an audio signal level (or `vol‐
+ ume') exceeds the range of the chosen representation. In most cases,
+ clipping is undesirable and so should be corrected by adjusting the
+ level prior to the point (in the processing chain) at which it occurs.
+
+ In SoX, clipping could occur, as you might expect, when using the vol
+ or gain effects to increase the audio volume. Clipping could also occur
+ with many other effects, when converting one format to another, and
+ even when simply playing the audio.
+
+ Playing an audio file often involves resampling, and processing by ana‐
+ logue components can introduce a small DC offset and/or amplification,
+ all of which can produce distortion if the audio signal level was ini‐
+ tially too close to the clipping point.
+
+ For these reasons, it is usual to make sure that an audio file's signal
+ level has some `headroom', i.e. it does not exceed a particular level
+ below the maximum possible level for the given representation. Some
+ standards bodies recommend as much as 9dB headroom, but in most cases,
+ 3dB (≈ 70% linear) is enough. Note that this wisdom seems to have been
+ lost in modern music production; in fact, many CDs, MP3s, etc. are now
+ mastered at levels above 0dBFS i.e. the audio is clipped as delivered.
+
+ SoX's stat and stats effects can assist in determining the signal level
+ in an audio file. The gain or vol effect can be used to prevent clip‐
+ ping, e.g.
+ sox dull.wav bright.wav gain -6 treble +6
+ guarantees that the treble boost will not clip.
+
+ If clipping occurs at any point during processing, SoX will display a
+ warning message to that effect.
+
+ See also -G and the gain and norm effects.
+
+ Input File Combining
+ SoX's input combiner can be configured (see OPTIONS below) to combine
+ multiple files using any of the following methods: `concatenate',
+ `sequence', `mix', `mix-power', `merge', or `multiply'. The default
+ method is `sequence' for play, and `concatenate' for rec and sox.
+
+ For all methods other than `sequence', multiple input files must have
+ the same sampling rate. If necessary, separate SoX invocations can be
+ used to make sampling rate adjustments prior to combining.
+
+ If the `concatenate' combining method is selected (usually, this will
+ be by default) then the input files must also have the same number of
+ channels. The audio from each input will be concatenated in the order
+ given to form the output file.
+
+ The `sequence' combining method is selected automatically for play. It
+ is similar to `concatenate' in that the audio from each input file is
+ sent serially to the output file. However, here the output file may be
+ closed and reopened at the corresponding transition between input
+ files. This may be just what is needed when sending different types of
+ audio to an output device, but is not generally useful when the output
+ is a normal file.
+
+ If either the `mix' or `mix-power' combining method is selected then
+ two or more input files must be given and will be mixed together to
+ form the output file. The number of channels in each input file need
+ not be the same, but SoX will issue a warning if they are not and some
+ channels in the output file will not contain audio from every input
+ file. A mixed audio file cannot be un-mixed without reference to the
+ original input files.
+
+ If the `merge' combining method is selected then two or more input
+ files must be given and will be merged together to form the output
+ file. The number of channels in each input file need not be the same.
+ A merged audio file comprises all of the channels from all of the input
+ files. Un-merging is possible using multiple invocations of SoX with
+ the remix effect. For example, two mono files could be merged to form
+ one stereo file. The first and second mono files would become the left
+ and right channels of the stereo file.
+
+ The `multiply' combining method multiplies the sample values of corre‐
+ sponding channels (treated as numbers in the interval -1 to +1). If
+ the number of channels in the input files is not the same, the missing
+ channels are considered to contain all zero.
+
+ When combining input files, SoX applies any specified effects (includ‐
+ ing, for example, the vol volume adjustment effect) after the audio has
+ been combined. However, it is often useful to be able to set the volume
+ of (i.e. `balance') the inputs individually, before combining takes
+ place.
+
+ For all combining methods, input file volume adjustments can be made
+ manually using the -v option (below) which can be given for one or more
+ input files. If it is given for only some of the input files then the
+ others receive no volume adjustment. In some circumstances, automatic
+ volume adjustments may be applied (see below).
+
+ The -V option (below) can be used to show the input file volume adjust‐
+ ments that have been selected (either manually or automatically).
+
+ There are some special considerations that need to made when mixing
+ input files:
+
+ Unlike the other methods, `mix' combining has the potential to cause
+ clipping in the combiner if no balancing is performed. In this case,
+ if manual volume adjustments are not given, SoX will try to ensure that
+ clipping does not occur by automatically adjusting the volume (ampli‐
+ tude) of each input signal by a factor of ¹/n, where n is the number of
+ input files. If this results in audio that is too quiet or otherwise
+ unbalanced then the input file volumes can be set manually as described
+ above. Using the norm effect on the mix is another alternative.
+
+ If mixed audio seems loud enough at some points but too quiet in others
+ then dynamic range compression should be applied to correct this - see
+ the compand effect.
+
+ With the `mix-power' combine method, the mixed volume is approximately
+ equal to that of one of the input signals. This is achieved by balanc‐
+ ing using a factor of ¹/√n instead of ¹/n. Note that this balancing
+ factor does not guarantee that clipping will not occur, but the number
+ of clips will usually be low and the resultant distortion is generally
+ imperceptible.
+
+ Output Files
+ SoX's default behaviour is to take one or more input files and write
+ them to a single output file.
+
+ This behaviour can be changed by specifying the pseudo-effect `newfile'
+ within the effects list. SoX will then enter multiple output mode.
+
+ In multiple output mode, a new file is created when the effects prior
+ to the `newfile' indicate they are done. The effects chain listed
+ after `newfile' is then started up and its output is saved to the new
+ file.
+
+ In multiple output mode, a unique number will automatically be appended
+ to the end of all filenames. If the filename has an extension then the
+ number is inserted before the extension. This behaviour can be custom‐
+ ized by placing a %n anywhere in the filename where the number should
+ be substituted. An optional number can be placed after the % to indi‐
+ cate a minimum fixed width for the number.
+
+ Multiple output mode is not very useful unless an effect that will stop
+ the effects chain early is specified before the `newfile'. If end of
+ file is reached before the effects chain stops itself then no new file
+ will be created as it would be empty.
+
+ The following is an example of splitting the first 60 seconds of an
+ input file into two 30 second files and ignoring the rest.
+ sox song.wav ringtone%1n.wav trim 0 30 : newfile : trim 0 30
+
+ Stopping SoX
+ Usually SoX will complete its processing and exit automatically once it
+ has read all available audio data from the input files.
+
+ If desired, it can be terminated earlier by sending an interrupt signal
+ to the process (usually by pressing the keyboard interrupt key which is
+ normally Ctrl-C). This is a natural requirement in some circumstances,
+ e.g. when using SoX to make a recording. Note that when using SoX to
+ play multiple files, Ctrl-C behaves slightly differently: pressing it
+ once causes SoX to skip to the next file; pressing it twice in quick
+ succession causes SoX to exit.
+
+ Another option to stop processing early is to use an effect that has a
+ time period or sample count to determine the stopping point. The trim
+ effect is an example of this. Once all effects chains have stopped
+ then SoX will also stop.
+
+FILENAMES
+ Filenames can be simple file names, absolute or relative path names, or
+ URLs (input files only). Note that URL support requires that wget(1)
+ is available.
+
+ Note: Giving SoX an input or output filename that is the same as a SoX
+ effect-name will not work since SoX will treat it as an effect
+ specification. The only work-around to this is to avoid such
+ filenames. This is generally not difficult since most audio filenames
+ have a filename `extension', whilst effect-names do not.
+
+ Special Filenames
+ The following special filenames may be used in certain circumstances in
+ place of a normal filename on the command line:
+
+ - SoX can be used in simple pipeline operations by using the
+ special filename `-' which, if used as an input filename, will
+ cause SoX will read audio data from `standard input' (stdin),
+ and which, if used as the output filename, will cause SoX will
+ send audio data to `standard output' (stdout). Note that when
+ using this option for the output file, and sometimes when using
+ it for an input file, the file-type (see -t below) must also be
+ given.
+
+ "|program [options] ..."
+ This can be used in place of an input filename to specify the
+ the given program's standard output (stdout) be used as an input
+ file. Unlike - (above), this can be used for several inputs to
+ one SoX command. For example, if `genw' generates mono WAV
+ formatted signals to its standard output, then the following
+ command makes a stereo file from two generated signals:
+ sox -M "|genw --imd -" "|genw --thd -" out.wav
+ For headerless (raw) audio, -t (and perhaps other format
+ options) will need to be given, preceding the input command.
+
+ "wildcard-filename"
+ Specifies that filename `globbing' (wild-card matching) should
+ be performed by SoX instead of by the shell. This allows a sin‐
+ gle set of file options to be applied to a group of files. For
+ example, if the current directory contains three `vox' files,
+ file1.vox, file2.vox, and file3.vox, then
+ play --rate 6k *.vox
+ will be expanded by the `shell' (in most environments) to
+ play --rate 6k file1.vox file2.vox file3.vox
+ which will treat only the first vox file as having a sample rate
+ of 6k. With
+ play --rate 6k "*.vox"
+ the given sample rate option will be applied to all three vox
+ files.
+
+ -p, --sox-pipe
+ This can be used in place of an output filename to specify that
+ the SoX command should be used as in input pipe to another SoX
+ command. For example, the command:
+ play "|sox -n -p synth 2" "|sox -n -p synth 2 tremolo 10" stat
+ plays two `files' in succession, each with different effects.
+
+ -p is in fact an alias for `-t sox -'.
+
+ -d, --default-device
+ This can be used in place of an input or output filename to
+ specify that the default audio device (if one has been built
+ into SoX) is to be used. This is akin to invoking rec or play
+ (as described above).
+
+ -n, --null
+ This can be used in place of an input or output filename to
+ specify that a `null file' is to be used. Note that here, `null
+ file' refers to a SoX-specific mechanism and is not related to
+ any operating-system mechanism with a similar name.
+
+ Using a null file to input audio is equivalent to using a normal
+ audio file that contains an infinite amount of silence, and as
+ such is not generally useful unless used with an effect that
+ specifies a finite time length (such as trim or synth).
+
+ Using a null file to output audio amounts to discarding the
+ audio and is useful mainly with effects that produce information
+ about the audio instead of affecting it (such as noiseprof or
+ stat).
+
+ The sampling rate associated with a null file is by default
+ 48 kHz, but, as with a normal file, this can be overridden if
+ desired using command-line format options (see below).
+
+ Supported File & Audio Device Types
+ See soxformat(7) for a list and description of the supported file for‐
+ mats and audio device drivers.
+
+OPTIONS
+ Global Options
+ These options can be specified on the command line at any point before
+ the first effect name.
+
+ The SOX_OPTS environment variable can be used to provide alternative
+ default values for SoX's global options. For example:
+ SOX_OPTS="--buffer 20000 --play-rate-arg -hs --temp /mnt/temp"
+ Note that setting SOX_OPTS can potentially create unwanted changes in
+ the behaviour of scripts or other programs that invoke SoX. SOX_OPTS
+ might best be used for things (such as in the given example) that
+ reflect the environment in which SoX is being run. Enabling options
+ such as --no-clobber as default might be handled better using a shell
+ alias since a shell alias will not affect operation in scripts etc.
+
+ One way to ensure that a script cannot be affected by SOX_OPTS is to
+ clear SOX_OPTS at the start of the script, but this of course loses the
+ benefit of SOX_OPTS carrying some system-wide default options. An
+ alternative approach is to explicitly invoke SoX with default option
+ values, e.g.
+ SOX_OPTS="-V --no-clobber"
+ ...
+ sox -V2 --clobber $input $output ...
+ Note that the way to set environment variables varies from system to
+ system. Here are some examples:
+
+ Unix bash:
+ export SOX_OPTS="-V --no-clobber"
+ Unix csh:
+ setenv SOX_OPTS "-V --no-clobber"
+ MS-DOS/MS-Windows:
+ set SOX_OPTS=-V --no-clobber
+ MS-Windows GUI: via Control Panel : System : Advanced : Environment
+ Variables
+
+ Mac OS X GUI: Refer to Apple's Technical Q&A QA1067 document.
+
+ --buffer BYTES, --input-buffer BYTES
+ Set the size in bytes of the buffers used for processing audio
+ (default 8192). --buffer applies to input, effects, and output
+ processing; --input-buffer applies only to input processing (for
+ which it overrides --buffer if both are given).
+
+ Be aware that large values for --buffer will cause SoX to be
+ become slow to respond to requests to terminate or to skip the
+ current input file.
+
+ --clobber
+ Don't prompt before overwriting an existing file with the same
+ name as that given for the output file. This is the default be‐
+ haviour.
+
+ --combine concatenate|merge|mix|mix-power|multiply|sequence
+ Select the input file combining method; for some of these, short
+ options are available: -m selects `mix', -M selects `merge', and
+ -T selects `multiply'.
+
+ See Input File Combining above for a description of the differ‐
+ ent combining methods.
+
+ -D, --no-dither
+ Disable automatic dither - see `Dithering' above. An example of
+ why this might occasionally be useful is if a file has been con‐
+ verted from 16 to 24 bit with the intention of doing some pro‐
+ cessing on it, but in fact no processing is needed after all and
+ the original 16 bit file has been lost, then, strictly speaking,
+ no dither is needed if converting the file back to 16 bit. See
+ also the stats effect for how to determine the actual bit depth
+ of the audio within a file.
+
+ --effects-file FILENAME
+ Use FILENAME to obtain all effects and their arguments. The
+ file is parsed as if the values were specified on the command
+ line. A new line can be used in place of the special : marker
+ to separate effect chains. For convenience, such markers at the
+ end of the file are normally ignored; if you want to specify an
+ empty last effects chain, use an explicit : by itself on the
+ last line of the file. This option causes any effects specified
+ on the command line to be discarded.
+
+ -G, --guard
+ Automatically invoke the gain effect to guard against clipping.
+ E.g.
+ sox -G infile -b 16 outfile rate 44100 dither -s
+ is shorthand for
+ sox infile -b 16 outfile gain -h rate 44100 gain -rh dither -s
+ See also -V, --norm, and the gain effect.
+
+ -h, --help
+ Show version number and usage information.
+
+ --help-effect NAME
+ Show usage information on the specified effect. The name all
+ can be used to show usage on all effects.
+
+ --help-format NAME
+ Show information about the specified file format. The name all
+ can be used to show information on all formats.
+
+ --i, --info
+ Only if given as the first parameter to sox, behave as soxi(1).
+
+ -m|-M Equivalent to --combine mix and --combine merge, respectively.
+
+ --magic
+ If SoX has been built with the optional `libmagic' library then
+ this option can be given to enable its use in helping to detect
+ audio file types.
+
+ --multi-threaded | --single-threaded
+ By default, SoX is `single threaded'. If the --multi-threaded
+ option is given however then SoX will process audio channels for
+ most multi-channel effects in parallel on hyper-threading/multi-
+ core architectures. This may reduce processing time, though
+ sometimes it may be necessary to use this option in conjunction
+ with a larger buffer size than is the default to gain any bene‐
+ fit from multi-threaded processing (e.g. 131072; see --buffer
+ above).
+
+ --no-clobber
+ Prompt before overwriting an existing file with the same name as
+ that given for the output file.
+
+ N.B. Unintentionally overwriting a file is easier than you
+ might think, for example, if you accidentally enter
+ sox file1 file2 effect1 effect2 ...
+ when what you really meant was
+ play file1 file2 effect1 effect2 ...
+ then, without this option, file2 will be overwritten. Hence,
+ using this option is recommended. SOX_OPTS (above), a `shell'
+ alias, script, or batch file may be an appropriate way of perma‐
+ nently enabling it.
+
+ --norm[=dB-level]
+ Automatically invoke the gain effect to guard against clipping
+ and to normalise the audio. E.g.
+ sox --norm infile -b 16 outfile rate 44100 dither -s
+ is shorthand for
+ sox infile -b 16 outfile gain -h rate 44100 gain -nh dither -s
+ Optionally, the audio can be normalized to a given level (usu‐
+ ally) below 0 dBFS:
+ sox --norm=-3 infile outfile
+
+ See also -V, -G, and the gain effect.
+
+ --play-rate-arg ARG
+ Selects a quality option to be used when the `rate' effect is
+ automatically invoked whilst playing audio. This option is typ‐
+ ically set via the SOX_OPTS environment variable (see above).
+
+ --plot gnuplot|octave|off
+ If not set to off (the default if --plot is not given), run in a
+ mode that can be used, in conjunction with the gnuplot program
+ or the GNU Octave program, to assist with the selection and con‐
+ figuration of many of the transfer-function based effects. For
+ the first given effect that supports the selected plotting pro‐
+ gram, SoX will output commands to plot the effect's transfer
+ function, and then exit without actually processing any audio.
+ E.g.
+ sox --plot octave input-file -n highpass 1320 > highpass.plt
+ octave highpass.plt
+
+ -q, --no-show-progress
+ Run in quiet mode when SoX wouldn't otherwise do so. This is
+ the opposite of the -S option.
+
+ -R Run in `repeatable' mode. When this option is given, where
+ applicable, SoX will embed a fixed time-stamp in the output file
+ (e.g. AIFF) and will `seed' pseudo random number generators
+ (e.g. dither) with a fixed number, thus ensuring that succes‐
+ sive SoX invocations with the same inputs and the same parame‐
+ ters yield the same output.
+
+ --replay-gain track|album|off
+ Select whether or not to apply replay-gain adjustment to input
+ files. The default is off for sox and rec, album for play where
+ (at least) the first two input files are tagged with the same
+ Artist and Album names, and track for play otherwise.
+
+ -S, --show-progress
+ Display input file format/header information, and processing
+ progress as input file(s) percentage complete, elapsed time, and
+ remaining time (if known; shown in brackets), and the number of
+ samples written to the output file. Also shown is a peak-level
+ meter, and an indication if clipping has occurred. The peak-
+ level meter shows up to two channels and is calibrated for digi‐
+ tal audio as follows (right channel shown):
+
+ dB FSD Display dB FSD Display
+ -25 - -11 ====
+ -23 = -9 ====-
+ -21 =- -7 =====
+ -19 == -5 =====-
+ -17 ==- -3 ======
+ -15 === -1 =====!
+ -13 ===-
+
+ A three-second peak-held value of headroom in dBs will be shown
+ to the right of the meter if this is below 6dB.
+
+ This option is enabled by default when using SoX to play or
+ record audio.
+
+ -T Equivalent to --combine multiply.
+
+ --temp DIRECTORY
+ Specify that any temporary files should be created in the given
+ DIRECTORY. This can be useful if there are permission or free-
+ space problems with the default location. In this case, using
+ `--temp .' (to use the current directory) is often a good solu‐
+ tion.
+
+ --version
+ Show SoX's version number and exit.
+
+ -V[level]
+ Set verbosity. This is particularly useful for seeing how any
+ automatic effects have been invoked by SoX.
+
+ SoX displays messages on the console (stderr) according to the
+ following verbosity levels:
+
+ 0 No messages are shown at all; use the exit status to
+ determine if an error has occurred.
+
+ 1 Only error messages are shown. These are generated if
+ SoX cannot complete the requested commands.
+
+ 2 Warning messages are also shown. These are generated if
+ SoX can complete the requested commands, but not exactly
+ according to the requested command parameters, or if
+ clipping occurs.
+
+ 3 Descriptions of SoX's processing phases are also shown.
+ Useful for seeing exactly how SoX is processing your
+ audio.
+
+ 4 and above
+ Messages to help with debugging SoX are also shown.
+
+ By default, the verbosity level is set to 2 (shows errors and
+ warnings). Each occurrence of the -V option increases the ver‐
+ bosity level by 1. Alternatively, the verbosity level can be
+ set to an absolute number by specifying it immediately after the
+ -V, e.g. -V0 sets it to 0.
+
+ Input File Options
+ These options apply only to input files and may precede only input
+ filenames on the command line.
+
+ --ignore-length
+ Override an (incorrect) audio length given in an audio file's
+ header. If this option is given then SoX will keep reading audio
+ until it reaches the end of the input file.
+
+ -v, --volume FACTOR
+ Intended for use when combining multiple input files, this
+ option adjusts the volume of the file that follows it on the
+ command line by a factor of FACTOR. This allows it to be `bal‐
+ anced' w.r.t. the other input files. This is a linear (ampli‐
+ tude) adjustment, so a number less than 1 decreases the volume
+ and a number greater than 1 increases it. If a negative number
+ is given then in addition to the volume adjustment, the audio
+ signal will be inverted.
+
+ See also the norm, vol, and gain effects, and see Input File
+ Balancing above.

+ These options apply to the input or output file whose name they immedi‐
+ ately precede on the command line and are used mainly when working with
+ headerless file formats or when specifying a format for the output file
+ that is different to that of the input file.
+
+ -b BITS, --bits BITS
+ The number of bits (a.k.a. bit-depth or sometimes word-length)
+ in each encoded sample. Not applicable to complex encodings
+ such as MP3 or GSM. Not necessary with encodings that have a
+ fixed number of bits, e.g. A/μ-law, ADPCM.
+
+ For an input file, the most common use for this option is to
+ inform SoX of the number of bits per sample in a `raw' (`header‐
+ less') audio file. For example
+ sox -r 16k -e signed -b 8 input.raw output.wav
+ converts a particular `raw' file to a self-describing `WAV'
+ file.
+
+ For an output file, this option can be used (perhaps along with
+ -e) to set the output encoding size. By default (i.e. if this
+ option is not given), the output encoding size will (providing
+ it is supported by the output file type) be set to the input
+ encoding size. For example
+ sox input.cdda -b 24 output.wav
+ converts raw CD digital audio (16-bit, signed-integer) to a
+ 24-bit (signed-integer) `WAV' file.
+
+ -c CHANNELS, --channels CHANNELS
+ The number of audio channels in the audio file. This can be any
+ number greater than zero.
+
+ For an input file, the most common use for this option is to
+ inform SoX of the number of channels in a `raw' (`headerless')
+ audio file. Occasionally, it may be useful to use this option
+ with a `headered' file, in order to override the (presumably
+ incorrect) value in the header - note that this is only sup‐
+ ported with certain file types. Examples:
+ sox -r 48k -e float -b 32 -c 2 input.raw output.wav
+ converts a particular `raw' file to a self-describing `WAV'
+ file.
+ play -c 1 music.wav
+ interprets the file data as belonging to a single channel
+ regardless of what is indicated in the file header. Note that
+ if the file does in fact have two channels, this will result in
+ the file playing at half speed.
+
+ For an output file, this option provides a shorthand for speci‐
+ fying that the channels effect should be invoked in order to
+ change (if necessary) the number of channels in the audio signal
+ to the number given. For example, the following two commands
+ are equivalent:
+ sox input.wav -c 1 output.wav bass -b 24
+ sox input.wav output.wav bass -b 24 channels 1
+ though the second form is more flexible as it allows the effects
+ to be ordered arbitrarily.
+
+ -e ENCODING, --encoding ENCODING
+ The audio encoding type. Sometimes needed with file-types that
+ support more than one encoding type. For example, with raw, WAV,
+ or AU (but not, for example, with MP3 or FLAC). The available
+ encoding types are as follows:
+
+ signed-integer
+ PCM data stored as signed (`two's complement') integers.
+ Commonly used with a 16 or 24 -bit encoding size. A
+ value of 0 represents minimum signal power.
+
+ unsigned-integer
+ PCM data stored as unsigned integers. Commonly used with
+ an 8-bit encoding size. A value of 0 represents maximum
+ signal power.
+
+ floating-point
+ PCM data stored as IEEE 753 single precision (32-bit) or
+ double precision (64-bit) floating-point (`real') num‐
+ bers. A value of 0 represents minimum signal power.
+
+ a-law International telephony standard for logarithmic encoding
+ to 8 bits per sample. It has a precision equivalent to
+ roughly 13-bit PCM and is sometimes encoded with reversed
+ bit-ordering (see the -X option).
+
+ u-law, mu-law
+ North American telephony standard for logarithmic encod‐
+ ing to 8 bits per sample. A.k.a. μ-law. It has a preci‐
+ sion equivalent to roughly 14-bit PCM and is sometimes
+ encoded with reversed bit-ordering (see the -X option).
+
+ oki-adpcm
+ OKI (a.k.a. VOX, Dialogic, or Intel) 4-bit ADPCM; it has
+ a precision equivalent to roughly 12-bit PCM. ADPCM is a
+ form of audio compression that has a good compromise
+ between audio quality and encoding/decoding speed.
+
+ ima-adpcm
+ IMA (a.k.a. DVI) 4-bit ADPCM; it has a precision equiva‐
+ lent to roughly 13-bit PCM.
+
+ ms-adpcm
+ Microsoft 4-bit ADPCM; it has a precision equivalent to
+ roughly 14-bit PCM.
+
+ gsm-full-rate
+ GSM is currently used for the vast majority of the
+ world's digital wireless telephone calls. It utilises
+ several audio formats with different bit-rates and asso‐
+ ciated speech quality. SoX has support for GSM's origi‐
+ nal 13kbps `Full Rate' audio format. It is usually CPU-
+ intensive to work with GSM audio.
+
+ Encoding names can be abbreviated where this would not be
+ ambiguous; e.g. `unsigned-integer' can be given as `un', but not
+ `u' (ambiguous with `u-law').
+
+ For an input file, the most common use for this option is to
+ inform SoX of the encoding of a `raw' (`headerless') audio file
+ (see the examples in -b and -c above).
+
+ For an output file, this option can be used (perhaps along with
+ -b) to set the output encoding type For example
+ sox input.cdda -e float output1.wav
+
+ sox input.cdda -b 64 -e float output2.wav
+ convert raw CD digital audio (16-bit, signed-integer) to float‐
+ ing-point `WAV' files (single & double precision respectively).
+
+ By default (i.e. if this option is not given), the output encod‐
+ ing type will (providing it is supported by the output file
+ type) be set to the input encoding type.
+
+ --no-glob
+ Specifies that filename `globbing' (wild-card matching) should
+ not be performed by SoX on the following filename. For example,
+ if the current directory contains the two files `five-sec‐
+ onds.wav' and `five*.wav', then
+ play --no-glob "five*.wav"
+ can be used to play just the single file `five*.wav'.
+
+ -r, --rate RATE[k]
+ Gives the sample rate in Hz (or kHz if appended with `k') of the
+ file.
+
+ For an input file, the most common use for this option is to
+ inform SoX of the sample rate of a `raw' (`headerless') audio
+ file (see the examples in -b and -c above). Occasionally it may
+ be useful to use this option with a `headered' file, in order to
+ override the (presumably incorrect) value in the header - note
+ that this is only supported with certain file types. For exam‐
+ ple, if audio was recorded with a sample-rate of say 48k from a
+ source that played back a little, say 1.5%, too slowly, then
+ sox -r 48720 input.wav output.wav
+ effectively corrects the speed by changing only the file header
+ (but see also the speed effect for the more usual solution to
+ this problem).
+
+ For an output file, this option provides a shorthand for speci‐
+ fying that the rate effect should be invoked in order to change
+ (if necessary) the sample rate of the audio signal to the given
+ value. For example, the following two commands are equivalent:
+ sox input.wav -r 48k output.wav bass -b 24
+ sox input.wav output.wav bass -b 24 rate 48k
+ though the second form is more flexible as it allows rate
+ options to be given, and allows the effects to be ordered arbi‐
+ trarily.
+
+ -t, --type FILE-TYPE
+ Gives the type of the audio file. For both input and output
+ files, this option is commonly used to inform SoX of the type a
+ `headerless' audio file (e.g. raw, mp3) where the actual/desired
+ type cannot be determined from a given filename extension. For
+ example:
+ another-command | sox -t mp3 - output.wav
+
+ sox input.wav -t raw output.bin
+ It can also be used to override the type implied by an input
+ filename extension, but if overriding with a type that has a
+ header, SoX will exit with an appropriate error message if such
+ a header is not actually present.
+
+ See soxformat(7) for a list of supported file types.
+
+ -L, --endian little
+ -B, --endian big
+ -x, --endian swap
+ These options specify whether the byte-order of the audio data
+ is, respectively, `little endian', `big endian', or the opposite
+ to that of the system on which SoX is being used. Endianness
+ applies only to data encoded as floating-point, or as signed or
+ unsigned integers of 16 or more bits. It is often necessary to
+ specify one of these options for headerless files, and sometimes
+ necessary for (otherwise) self-describing files. A given
+ endian-setting option may be ignored for an input file whose
+ header contains a specific endianness identifier, or for an out‐
+ put file that is actually an audio device.
+
+ N.B. Unlike other format characteristics, the endianness (byte,
+ nibble, & bit ordering) of the input file is not automatically
+ used for the output file; so, for example, when the following is
+ run on a little-endian system:
+ sox -B audio.s16 trimmed.s16 trim 2
+ trimmed.s16 will be created as little-endian;
+ sox -B audio.s16 -B trimmed.s16 trim 2
+ must be used to preserve big-endianness in the output file.
+
+ The -V option can be used to check the selected orderings.
+
+ -N, --reverse-nibbles
+ Specifies that the nibble ordering (i.e. the 2 halves of a byte)
+ of the samples should be reversed; sometimes useful with ADPCM-
+ based formats.
+
+ N.B. See also N.B. in section on -x above.
+
+ -X, --reverse-bits
+ Specifies that the bit ordering of the samples should be
+ reversed; sometimes useful with a few (mostly headerless) for‐
+ mats.
+
+ N.B. See also N.B. in section on -x above.
+
+ Output File Format Options
+ These options apply only to the output file and may precede only the
+ output filename on the command line.
+
+ --add-comment TEXT
+ Append a comment in the output file header (where applicable).
+
+ --comment TEXT
+ Specify the comment text to store in the output file header
+ (where applicable).
+
+ SoX will provide a default comment if this option (or --com‐
+ ment-file) is not given. To specify that no comment should be
+ stored in the output file, use --comment "" .
+
+ --comment-file FILENAME
+ Specify a file containing the comment text to store in the out‐
+ put file header (where applicable).
+
+ -C, --compression FACTOR
+ The compression factor for variably compressing output file for‐
+ mats. If this option is not given then a default compression
+ factor will apply. The compression factor is interpreted dif‐
+ ferently for different compressing file formats. See the
+ description of the file formats that use this option in soxfor‐
+ mat(7) for more information.
+
+EFFECTS
+ In addition to converting, playing and recording audio files, SoX can
+ be used to invoke a number of audio `effects'. Multiple effects may be
+ applied by specifying them one after another at the end of the SoX com‐
+ mand line, forming an `effects chain'. Note that applying multiple
+ effects in real-time (i.e. when playing audio) is likely to require a
+ high performance computer. Stopping other applications may alleviate
+ performance issues should they occur.
+
+ Some of the SoX effects are primarily intended to be applied to a sin‐
+ gle instrument or `voice'. To facilitate this, the remix effect and
+ the global SoX option -M can be used to isolate then recombine tracks
+ from a multi-track recording.
+
+ Multiple Effects Chains
+ A single effects chain is made up of one or more effects. Audio from
+ the input runs through the chain until either the end of the input file
+ is reached or an effect in the chain requests to terminate the chain.
+
+ SoX supports running multiple effects chains over the input audio. In
+ this case, when one chain indicates it is done processing audio, the
+ audio data is then sent through the next effects chain. This continues
+ until either no more effects chains exist or the input has reached the
+ end of the file.
+
+ An effects chain is terminated by placing a : (colon) after an effect.
+ Any following effects are a part of a new effects chain.
+
+ It is important to place the effect that will stop the chain as the
+ first effect in the chain. This is because any samples that are
+ buffered by effects to the left of the terminating effect will be dis‐
+ carded. The amount of samples discarded is related to the --buffer
+ option and it should be kept small, relative to the sample rate, if the
+ terminating effect cannot be first. Further information on stopping
+ effects can be found in the Stopping SoX section.
+
+ There are a few pseudo-effects that aid using multiple effects chains.
+ These include newfile which will start writing to a new output file
+ before moving to the next effects chain and restart which will move
+ back to the first effects chain. Pseudo-effects must be specified as
+ the first effect in a chain and as the only effect in a chain (they
+ must have a : before and after they are specified).
+
+ The following is an example of multiple effects chains. It will split
+ the input file into multiple files of 30 seconds in length. Each out‐
+ put filename will have unique number in its name as documented in the
+ Output Files section.
+ sox infile.wav output.wav trim 0 30 : newfile : restart
+
+ Common Notation And Parameters
+ In the descriptions that follow, brackets [ ] are used to denote param‐
+ eters that are optional, braces { } to denote those that are both
+ optional and repeatable, and angle brackets < > to denote those that
+ are repeatable but not optional. Where applicable, default values for
+ optional parameters are shown in parenthesis ( ).
+
+ The following parameters are used with, and have the same meaning for,
+ several effects:
+
+ center[k]
+ See frequency.
+
+ frequency[k]
+ A frequency in Hz, or, if appended with `k', kHz.
+
+ gain A power gain in dB. Zero gives no gain; less than zero gives an
+ attenuation.
+
+ position
+ A position within the audio stream; the syntax is [=|+|-]time‐
+ spec, where timespec is a time specification (see below). The
+ optional first character indicates whether the timespec is to be
+ interpreted relative to the start (=) or end (-) of audio, or to
+ the previous position if the effect accepts multiple position
+ arguments (+). The audio length must be known for end-relative
+ locations to work; some effects do accept -0 for end-of-audio,
+ though, even if the length is unknown. Which of =, +, - is the
+ default depends on the effect and is shown in its syntax as,
+ e.g., position(+).
+
+ Examples: =2:00 (two minutes into the audio stream), -100s (one
+ hundred samples before the end of audio), +0:12+10s (twelve sec‐
+ onds and ten samples after the previous position), -0.5+1s (one
+ sample less than half a second before the end of audio).
+
+ width[h|k|o|q]
+ Used to specify the band-width of a filter. A number of differ‐
+ ent methods to specify the width are available (though not all
+ for every effect). One of the characters shown may be appended
+ to select the desired method as follows:
+
+ Method Notes
+ h Hz
+ k kHz
+ o Octaves
+ q Q-factor See [2]
+
+ For each effect that uses this parameter, the default method
+ (i.e. if no character is appended) is the one that it listed
+ first in the first line of the effect's description.
+
+ Most effects that expect an audio position or duration in a parameter,
+ i.e. a time specification, accept either of the following two forms:
+
+ [[hours:]minutes:]seconds[.frac][t]
+ A specification of `1:30.5' corresponds to one minute, thirty
+ and ½ seconds. The t suffix is entirely optional (however, see
+ the silence effect for an exception). Note that the component
+ values do not have to be normalized; e.g., `1:23:45', `83:45',
+ `79:0285', `1:0:1425', `1::1425' and `5025' all are legal and
+ equivalent to each other.
+
+ sampless
+ Specifies the number of samples directly, as in `8000s'. For
+ large sample counts, e notation is supported: `1.7e6s' is the
+ same as `1700000s'.
+
+ Time specifications can also be chained with + or - into a new time
+ specification where the right part is added to or subtracted from the
+ left, respectively: `3:00-200s' means two hundred samples less than
+ three minutes.
+
+ To see if SoX has support for an optional effect, enter sox -h and look
+ for its name under the list: `EFFECTS'.
+
+ Supported Effects
+ Note: a categorised list of the effects can be found in the accompany‐
+ ing `README' file.
+
+ allpass frequency[k] width[h|k|o|q]
+ Apply a two-pole all-pass filter with central frequency (in Hz)
+ frequency, and filter-width width. An all-pass filter changes
+ the audio's frequency to phase relationship without changing its
+ frequency to amplitude relationship. The filter is described in
+ detail in [1].
+
+ This effect supports the --plot global option.
+
+ band [-n] center[k] [width[h|k|o|q]]
+ Apply a band-pass filter. The frequency response drops loga‐
+ rithmically around the center frequency. The width parameter
+ gives the slope of the drop. The frequencies at center + width
+ and center - width will be half of their original amplitudes.
+ band defaults to a mode oriented to pitched audio, i.e. voice,
+ singing, or instrumental music. The -n (for noise) option uses
+ the alternate mode for un-pitched audio (e.g. percussion).
+ Warning: -n introduces a power-gain of about 11dB in the filter,
+ so beware of output clipping. band introduces noise in the
+ shape of the filter, i.e. peaking at the center frequency and
+ settling around it.
+
+ This effect supports the --plot global option.
+
+ See also sinc for a bandpass filter with steeper shoulders.
+
+ bandpass|bandreject [-c] frequency[k] width[h|k|o|q]
+ Apply a two-pole Butterworth band-pass or band-reject filter
+ with central frequency frequency, and (3dB-point) band-width
+ width. The -c option applies only to bandpass and selects a
+ constant skirt gain (peak gain = Q) instead of the default: con‐
+ stant 0dB peak gain. The filters roll off at 6dB per octave
+ (20dB per decade) and are described in detail in [1].
+
+ These effects support the --plot global option.
+
+ See also sinc for a bandpass filter with steeper shoulders.
+
+ bandreject frequency[k] width[h|k|o|q]
+ Apply a band-reject filter. See the description of the bandpass
+ effect for details.
+
+ bass|treble gain [frequency[k] [width[s|h|k|o|q]]]
+ Boost or cut the bass (lower) or treble (upper) frequencies of
+ the audio using a two-pole shelving filter with a response simi‐
+ lar to that of a standard hi-fi's tone-controls. This is also
+ known as shelving equalisation (EQ).
+
+ gain gives the gain at 0 Hz (for bass), or whichever is the
+ lower of ∼22 kHz and the Nyquist frequency (for treble). Its
+ useful range is about -20 (for a large cut) to +20 (for a large
+ boost). Beware of Clipping when using a positive gain.
+
+ If desired, the filter can be fine-tuned using the following
+ optional parameters:
+
+ frequency sets the filter's central frequency and so can be used
+ to extend or reduce the frequency range to be boosted or cut.
+ The default value is 100 Hz (for bass) or 3 kHz (for treble).
+
+ width determines how steep is the filter's shelf transition. In
+ addition to the common width specification methods described
+ above, `slope' (the default, or if appended with `s') may be
+ used. The useful range of `slope' is about 0.3, for a gentle
+ slope, to 1 (the maximum), for a steep slope; the default value
+ is 0.5.
+
+ The filters are described in detail in [1].
+
+ These effects support the --plot global option.
+
+ See also equalizer for a peaking equalisation effect.
+
+ bend [-f frame-rate(25)] [-o over-sample(16)] { start-posi‐
+ tion(+),cents,end-position(+) }
+ Changes pitch by specified amounts at specified times. Each
+ given triple: start-position,cents,end-position specifies one
+ bend. cents is the number of cents (100 cents = 1 semitone) by
+ which to bend the pitch. The other values specify the points in
+ time at which to start and end bending the pitch, respectively.
+
+ The pitch-bending algorithm utilises the Discrete Fourier Trans‐
+ form (DFT) at a particular frame rate and over-sampling rate.
+ The -f and -o parameters may be used to adjust these parameters
+ and thus control the smoothness of the changes in pitch.
+
+ For example, an initial tone is generated, then bent three
+ times, yielding four different notes in total:
+ play -n synth 2.5 sin 667 gain 1 \
+ bend .35,180,.25 .15,740,.53 0,-520,.3
+ Here, the first bend runs from 0.35 to 0.6, and the second one
+ from 0.75 to 1.28 seconds. Note that the clipping that is pro‐
+ duced in this example is deliberate; to remove it, use gain -5
+ in place of gain 1.
+
+ See also pitch.
+
+ biquad b0 b1 b2 a0 a1 a2
+ Apply a biquad IIR filter with the given coefficients. Where b*
+ and a* are the numerator and denominator coefficients respec‐
+ tively.
+
+ See http://en.wikipedia.org/wiki/Digital_biquad_filter (where a0
+ = 1).
+
+ This effect supports the --plot global option.
+
+ channels CHANNELS
+ Invoke a simple algorithm to change the number of channels in
+ the audio signal to the given number CHANNELS: mixing if
+ decreasing the number of channels or duplicating if increasing
+ the number of channels.
+
+ The channels effect is invoked automatically if SoX's -c option
+ specifies a number of channels that is different to that of the
+ input file(s). Alternatively, if this effect is given explic‐
+ itly, then SoX's -c option need not be given. For example, the
+ following two commands are equivalent:
+ sox input.wav -c 1 output.wav bass -b 24
+ sox input.wav output.wav bass -b 24 channels 1
+ though the second form is more flexible as it allows the effects
+ to be ordered arbitrarily.
+
+ See also remix for an effect that allows channels to be
+ mixed/selected arbitrarily.
+
+ chorus gain-in gain-out <delay decay speed depth -s|-t>
+ Add a chorus effect to the audio. This can make a single vocal
+ sound like a chorus, but can also be applied to instrumentation.
+
+ Chorus resembles an echo effect with a short delay, but whereas
+ with echo the delay is constant, with chorus, it is varied using
+ sinusoidal or triangular modulation. The modulation depth
+ defines the range the modulated delay is played before or after
+ the delay. Hence the delayed sound will sound slower or faster,
+ that is the delayed sound tuned around the original one, like in
+ a chorus where some vocals are slightly off key. See [3] for
+ more discussion of the chorus effect.
+
+ Each four-tuple parameter delay/decay/speed/depth gives the
+ delay in milliseconds and the decay (relative to gain-in) with a
+ modulation speed in Hz using depth in milliseconds. The modula‐
+ tion is either sinusoidal (-s) or triangular (-t). Gain-out is
+ the volume of the output.
+
+ A typical delay is around 40ms to 60ms; the modulation speed is
+ best near 0.25Hz and the modulation depth around 2ms. For exam‐
+ ple, a single delay:
+ play guitar1.wav chorus 0.7 0.9 55 0.4 0.25 2 -t
+ Two delays of the original samples:
+ play guitar1.wav chorus 0.6 0.9 50 0.4 0.25 2 -t \
+ 60 0.32 0.4 1.3 -s
+ A fuller sounding chorus (with three additional delays):
+ play guitar1.wav chorus 0.5 0.9 50 0.4 0.25 2 -t \
+ 60 0.32 0.4 2.3 -t 40 0.3 0.3 1.3 -s
+
+ compand attack1,decay1{,attack2,decay2}
+ [soft-knee-dB:]in-dB1[,out-dB1]{,in-dB2,out-dB2}
+ [gain [initial-volume-dB [delay]]]
+
+ Compand (compress or expand) the dynamic range of the audio.
+
+ The attack and decay parameters (in seconds) determine the time
+ over which the instantaneous level of the input signal is aver‐
+ aged to determine its volume; attacks refer to increases in vol‐
+ ume and decays refer to decreases. For most situations, the
+ attack time (response to the music getting louder) should be
+ shorter than the decay time because the human ear is more sensi‐
+ tive to sudden loud music than sudden soft music. Where more
+ than one pair of attack/decay parameters are specified, each
+ input channel is companded separately and the number of pairs
+ must agree with the number of input channels. Typical values
+ are 0.3,0.8 seconds.
+
+ The second parameter is a list of points on the compander's
+ transfer function specified in dB relative to the maximum possi‐
+ ble signal amplitude. The input values must be in a strictly
+ increasing order but the transfer function does not have to be
+ monotonically rising. If omitted, the value of out-dB1 defaults
+ to the same value as in-dB1; levels below in-dB1 are not com‐
+ panded (but may have gain applied to them). The point 0,0 is
+ assumed but may be overridden (by 0,out-dBn). If the list is
+ preceded by a soft-knee-dB value, then the points at where adja‐
+ cent line segments on the transfer function meet will be rounded
+ by the amount given. Typical values for the transfer function
+ are 6:-70,-60,-20.
+
+ The third (optional) parameter is an additional gain in dB to be
+ applied at all points on the transfer function and allows easy
+ adjustment of the overall gain.
+
+ The fourth (optional) parameter is an initial level to be
+ assumed for each channel when companding starts. This permits
+ the user to supply a nominal level initially, so that, for exam‐
+ ple, a very large gain is not applied to initial signal levels
+ before the companding action has begun to operate: it is quite
+ probable that in such an event, the output would be severely
+ clipped while the compander gain properly adjusts itself. A
+ typical value (for audio which is initially quiet) is -90 dB.
+
+ The fifth (optional) parameter is a delay in seconds. The input
+ signal is analysed immediately to control the compander, but it
+ is delayed before being fed to the volume adjuster. Specifying
+ a delay approximately equal to the attack/decay times allows the
+ compander to effectively operate in a `predictive' rather than a
+ reactive mode. A typical value is 0.2 seconds.
+
+ * * *
+
+ The following example might be used to make a piece of music
+ with both quiet and loud passages suitable for listening to in a
+ noisy environment such as a moving vehicle:
+ sox asz.wav asz-car.wav compand 0.3,1 6:-70,-60,-20 -5 -90 0.2
+ The transfer function (`6:-70,...') says that very soft sounds
+ (below -70dB) will remain unchanged. This will stop the compan‐
+ der from boosting the volume on `silent' passages such as
+ between movements. However, sounds in the range -60dB to 0dB
+ (maximum volume) will be boosted so that the 60dB dynamic range
+ of the original music will be compressed 3-to-1 into a 20dB
+ range, which is wide enough to enjoy the music but narrow enough
+ to get around the road noise. The `6:' selects 6dB soft-knee
+ companding. The -5 (dB) output gain is needed to avoid clipping
+ (the number is inexact, and was derived by experimentation).
+ The -90 (dB) for the initial volume will work fine for a clip
+ that starts with near silence, and the delay of 0.2 (seconds)
+ has the effect of causing the compander to react a bit more
+ quickly to sudden volume changes.
+
+ In the next example, compand is being used as a noise-gate for
+ when the noise is at a lower level than the signal:
+ play infile compand .1,.2 -inf,-50.1,-inf,-50,-50 0 -90 .1
+ Here is another noise-gate, this time for when the noise is at a
+ higher level than the signal (making it, in some ways, similar
+ to squelch):
+ play infile compand .1,.1 -45.1,-45,-inf,0,-inf 45 -90 .1
+ This effect supports the --plot global option (for the transfer
+ function).
+
+ See also mcompand for a multiple-band companding effect.
+
+ contrast [enhancement-amount(75)]
+ Comparable with compression, this effect modifies an audio sig‐
+ nal to make it sound louder. enhancement-amount controls the
+ amount of the enhancement and is a number in the range 0-100.
+ Note that enhancement-amount = 0 still gives a significant con‐
+ trast enhancement.
+
+ See also the compand and mcompand effects.
+
+ dcshift shift [limitergain]
+ Apply a DC shift to the audio. This can be useful to remove a
+ DC offset (caused perhaps by a hardware problem in the recording
+ chain) from the audio. The effect of a DC offset is reduced
+ headroom and hence volume. The stat or stats effect can be used
+ to determine if a signal has a DC offset.
+
+ The given dcshift value is a floating point number in the range
+ of ±2 that indicates the amount to shift the audio (which is in
+ the range of ±1).
+
+ An optional limitergain can be specified as well. It should
+ have a value much less than 1 (e.g. 0.05 or 0.02) and is used
+ only on peaks to prevent clipping.
+
+ * * *
+
+ An alternative approach to removing a DC offset (albeit with a
+ short delay) is to use the highpass filter effect at a frequency
+ of say 10Hz, as illustrated in the following example:
+ sox -n dc.wav synth 5 sin %0 50
+ sox dc.wav fixed.wav highpass 10
+
+ deemph Apply Compact Disc (IEC 60908) de-emphasis (a treble attenuation
+ shelving filter).
+
+ Pre-emphasis was applied in the mastering of some CDs issued in
+ the early 1980s. These included many classical music albums, as
+ well as now sought-after issues of albums by The Beatles, Pink
+ Floyd and others. Pre-emphasis should be removed at playback
+ time by a de-emphasis filter in the playback device. However,
+ not all modern CD players have this filter, and very few PC CD
+ drives have it; playing pre-emphasised audio without the correct
+ de-emphasis filter results in audio that sounds harsh and is far
+ from what its creators intended.
+
+ With the deemph effect, it is possible to apply the necessary
+ de-emphasis to audio that has been extracted from a pre-empha‐
+ sised CD, and then either burn the de-emphasised audio to a new
+ CD (which will then play correctly on any CD player), or simply
+ play the correctly de-emphasised audio files on the PC. For
+ example:
+ sox track1.wav track1-deemph.wav deemph
+ and then burn track1-deemph.wav to CD, or
+ play track1-deemph.wav
+ or simply
+ play track1.wav deemph
+ The de-emphasis filter is implemented as a biquad and requires
+ the input audio sample rate to be either 44.1kHz or 48kHz. Max‐
+ imum deviation from the ideal response is only 0.06dB (up to
+ 20kHz).
+
+ This effect supports the --plot global option.
+
+ See also the bass and treble shelving equalisation effects.
+
+ delay {position(=)}
+ Delay one or more audio channels such that they start at the
+ given position. For example, delay 1.5 +1 3000s delays the
+ first channel by 1.5 seconds, the second channel by 2.5 seconds
+ (one second more than the previous channel), the third channel
+ by 3000 samples, and leaves any other channels that may be
+ present un-delayed. The following (one long) command plays a
+ chime sound:
+ play -n synth -j 3 sin %3 sin %-2 sin %-5 sin %-9 \
+ sin %-14 sin %-21 fade h .01 2 1.5 delay \
+ 1.3 1 .76 .54 .27 remix - fade h 0 2.7 2.5 norm -1
+ and this plays a guitar chord:
+ play -n synth pl G2 pl B2 pl D3 pl G3 pl D4 pl G4 \
+ delay 0 .05 .1 .15 .2 .25 remix - fade 0 4 .1 norm -1
+
+ dither [-S|-s|-f filter] [-a] [-p precision]
+ Apply dithering to the audio. Dithering deliberately adds a
+ small amount of noise to the signal in order to mask audible
+ quantization effects that can occur if the output sample size is
+ less than 24 bits. With no options, this effect will add trian‐
+ gular (TPDF) white noise. Noise-shaping (only for certain sam‐
+ ple rates) can be selected with -s. With the -f option, it is
+ possible to select a particular noise-shaping filter from the
+ following list: lipshitz, f-weighted, modified-e-weighted,
+ improved-e-weighted, gesemann, shibata, low-shibata, high-shi‐
+ bata. Note that most filter types are available only with
+ 44100Hz sample rate. The filter types are distinguished by the
+ following properties: audibility of noise, level of (inaudible,
+ but in some circumstances, otherwise problematic) shaped high
+ frequency noise, and processing speed.
+ See http://sox.sourceforge.net/SoX/NoiseShaping for graphs of
+ the different noise-shaping curves.
+
+ The -S option selects a slightly `sloped' TPDF, biased towards
+ higher frequencies. It can be used at any sampling rate but
+ below ≈22k, plain TPDF is probably better, and above ≈ 37k,
+ noise-shaping (if available) is probably better.
+
+ The -a option enables a mode where dithering (and noise-shaping
+ if applicable) are automatically enabled only when needed. The
+ most likely use for this is when applying fade in or out to an
+ already dithered file, so that the redithering applies only to
+ the faded portions. However, auto dithering is not fool-proof,
+ so the fades should be carefully checked for any noise modula‐
+ tion; if this occurs, then either re-dither the whole file, or
+ use trim, fade, and concatencate.
+
+ The -p option allows overriding the target precision.
+
+ If the SoX global option -R option is not given, then the
+ pseudo-random number generator used to generate the white noise
+ will be `reseeded', i.e. the generated noise will be different
+ between invocations.
+
+ This effect should not be followed by any other effect that
+ affects the audio.
+
+ See also the `Dithering' section above.
+
+ downsample [factor(2)]
+ Downsample the signal by an integer factor: Only the first out
+ of each factor samples is retained, the others are discarded.
+
+ No decimation filter is applied. If the input is not a properly
+ bandlimited baseband signal, aliasing will occur. This may be
+ desirable, e.g., for frequency translation.
+
+ For a general resampling effect with anti-aliasing, see rate.
+ See also upsample.
+
+ earwax Makes audio easier to listen to on headphones. Adds `cues' to
+ 44.1kHz stereo (i.e. audio CD format) audio so that when lis‐
+ tened to on headphones the stereo image is moved from inside
+ your head (standard for headphones) to outside and in front of
+ the listener (standard for speakers).
+
+ echo gain-in gain-out <delay decay>
+ Add echoing to the audio. Echoes are reflected sound and can
+ occur naturally amongst mountains (and sometimes large build‐
+ ings) when talking or shouting; digital echo effects emulate
+ this behaviour and are often used to help fill out the sound of
+ a single instrument or vocal. The time difference between the
+ original signal and the reflection is the `delay' (time), and
+ the loudness of the reflected signal is the `decay'. Multiple
+ echoes can have different delays and decays.
+
+ Each given delay decay pair gives the delay in milliseconds and
+ the decay (relative to gain-in) of that echo. Gain-out is the
+ volume of the output. For example: This will make it sound as
+ if there are twice as many instruments as are actually playing:
+ play lead.aiff echo 0.8 0.88 60 0.4
+ If the delay is very short, then it sound like a (metallic) ro‐
+ bot playing music:
+ play lead.aiff echo 0.8 0.88 6 0.4
+ A longer delay will sound like an open air concert in the moun‐
+ tains:
+ play lead.aiff echo 0.8 0.9 1000 0.3
+ One mountain more, and:
+ play lead.aiff echo 0.8 0.9 1000 0.3 1800 0.25
+
+ echos gain-in gain-out <delay decay>
+ Add a sequence of echoes to the audio. Each delay decay pair
+ gives the delay in milliseconds and the decay (relative to gain-
+ in) of that echo. Gain-out is the volume of the output.
+
+ Like the echo effect, echos stand for `ECHO in Sequel', that is
+ the first echos takes the input, the second the input and the
+ first echos, the third the input and the first and the second
+ echos, ... and so on. Care should be taken using many echos; a
+ single echos has the same effect as a single echo.
+
+ The sample will be bounced twice in symmetric echos:
+ play lead.aiff echos 0.8 0.7 700 0.25 700 0.3
+ The sample will be bounced twice in asymmetric echos:
+ play lead.aiff echos 0.8 0.7 700 0.25 900 0.3
+ The sample will sound as if played in a garage:
+ play lead.aiff echos 0.8 0.7 40 0.25 63 0.3
+
+ equalizer frequency[k] width[q|o|h|k] gain
+ Apply a two-pole peaking equalisation (EQ) filter. With this
+ filter, the signal-level at and around a selected frequency can
+ be increased or decreased, whilst (unlike band-pass and band-
+ reject filters) that at all other frequencies is unchanged.
+
+ frequency gives the filter's central frequency in Hz, width, the
+ band-width, and gain the required gain or attenuation in dB.
+ Beware of Clipping when using a positive gain.
+
+ In order to produce complex equalisation curves, this effect can
+ be given several times, each with a different central frequency.
+
+ The filter is described in detail in [1].
+
+ This effect supports the --plot global option.
+
+ See also bass and treble for shelving equalisation effects.
+
+ fade [type] fade-in-length [stop-position(=) [fade-out-length]]
+ Apply a fade effect to the beginning, end, or both of the audio.
+
+ An optional type can be specified to select the shape of the
+ fade curve: q for quarter of a sine wave, h for half a sine
+ wave, t for linear (`triangular') slope, l for logarithmic, and
+ p for inverted parabola. The default is logarithmic.
+
+ A fade-in starts from the first sample and ramps the signal
+ level from 0 to full volume over the time given as fade-in-
+ length. Specify 0 if no fade-in is wanted.
+
+ For fade-outs, the audio will be truncated at stop-position and
+ the signal level will be ramped from full volume down to 0 over
+ an interval of fade-out-length before the stop-position. If
+ fade-out-length is not specified, it defaults to the same value
+ as fade-in-length. No fade-out is performed if stop-position is
+ not specified. If the audio length can be determined from the
+ input file header and any previous effects, then -0 (or, for
+ historical reasons, 0) may be specified for stop-position to
+ indicate the usual case of a fade-out that ends at the end of
+ the input audio stream.
+
+ Any time specification may be used for fade-in-length and fade-
+ out-length.
+
+ See also the splice effect.
+
+ fir [coefs-file|coefs]
+ Use SoX's FFT convolution engine with given FIR filter coeffi‐
+ cients. If a single argument is given then this is treated as
+ the name of a file containing the filter coefficients (white-
+ space separated; may contain `#' comments). If the given file‐
+ name is `-', or if no argument is given, then the coefficients
+ are read from the `standard input' (stdin); otherwise, coeffi‐
+ cients may be given on the command line. Examples:
+ sox infile outfile fir 0.0195 -0.082 0.234 0.891 -0.145 0.043
+ sox infile outfile fir coefs.txt
+ with coefs.txt containing

+ 5.1031563346705155e-01
+ -6.6502926320995331e-02
+ ...
+
+ This effect supports the --plot global option.
+
+ flanger [delay depth regen width speed shape phase interp]
+ Apply a flanging effect to the audio. See [3] for a detailed
+ description of flanging.
+
+ All parameters are optional (right to left).
+
+ Range Default Description
+ delay 0 - 30 0 Base delay in milliseconds.
+ depth 0 - 10 2 Added swept delay in milliseconds.
+ regen -95 - 95 0 Percentage regeneration (delayed

+ shape sin Swept wave shape: sine|triangle.
+ phase 0 - 100 25 Swept wave percentage phase-shift
+ for multi-channel (e.g. stereo)
+ flange; 0 = 100 = same phase on
+ each channel.
+ interp lin Digital delay-line interpolation:
+ linear|quadratic.
+
+ gain [-e|-B|-b|-r] [-n] [-l|-h] [gain-dB]
+ Apply amplification or attenuation to the audio signal, or, in
+ some cases, to some of its channels. Note that use of any of
+ -e, -B, -b, -r, or -n requires temporary file space to store the
+ audio to be processed, so may be unsuitable for use with
+ `streamed' audio.
+
+ Without other options, gain-dB is used to adjust the signal
+ power level by the given number of dB: positive amplifies
+ (beware of Clipping), negative attenuates. With other options,
+ the gain-dB amplification or attenuation is (logically) applied
+ after the processing due to those options.
+
+ Given the -e option, the levels of the audio channels of a
+ multi-channel file are `equalised', i.e. gain is applied to all
+ channels other than that with the highest peak level, such that
+ all channels attain the same peak level (but, without also giv‐
+ ing -n, the audio is not `normalised').
+
+ The -B (balance) option is similar to -e, but with -B, the RMS
+ level is used instead of the peak level. -B might be used to
+ correct stereo imbalance caused by an imperfect record turntable
+ cartridge. Note that unlike -e, -B might cause some clipping.
+
+ -b is similar to -B but has clipping protection, i.e. if neces‐
+ sary to prevent clipping whilst balancing, attenuation is
+ applied to all channels. Note, however, that in conjunction
+ with -n, -B and -b are synonymous.
+
+ The -r option is used in conjunction with a prior invocation of
+ gain with the -h option - see below for details.
+
+ The -n option normalises the audio to 0dB FSD; it is often used
+ in conjunction with a negative gain-dB to the effect that the
+ audio is normalised to a given level below 0dB. For example,
+ sox infile outfile gain -n
+ normalises to 0dB, and
+ sox infile outfile gain -n -3
+ normalises to -3dB.
+
+ The -l option invokes a simple limiter, e.g.
+ sox infile outfile gain -l 6
+ will apply 6dB of gain but never clip. Note that limiting more
+ than a few dBs more than occasionally (in a piece of audio) is
+ not recommended as it can cause audible distortion. See the
+ compand effect for a more capable limiter.
+
+ The -h option is used to apply gain to provide head-room for
+ subsequent processing. For example, with
+ sox infile outfile gain -h bass +6
+ 6dB of attenuation will be applied prior to the bass boosting
+ effect thus ensuring that it will not clip. Of course, with
+ bass, it is obvious how much headroom will be needed, but with
+ other effects (e.g. rate, dither) it is not always as clear.
+ Another advantage of using gain -h rather than an explicit
+ attenuation, is that if the headroom is not used by subsequent
+ effects, it can be reclaimed with gain -r, for example:
+ sox infile outfile gain -h bass +6 rate 44100 gain -r
+ The above effects chain guarantees never to clip nor amplify; it
+ attenuates if necessary to prevent clipping, but by only as much
+ as is needed to do so.
+
+ Output formatting (dithering and bit-depth reduction) also
+ requires headroom (which cannot be `reclaimed'), e.g.
+ sox infile outfile gain -h bass +6 rate 44100 gain -rh dither
+ Here, the second gain invocation, reclaims as much of the head‐
+ room as it can from the preceding effects, but retains as much
+ headroom as is needed for subsequent processing. The SoX global
+ option -G can be given to automatically invoke gain -h and gain
+ -r.
+
+ See also the norm and vol effects.
+
+ highpass|lowpass [-1|-2] frequency[k] [width[q|o|h|k]]
+ Apply a high-pass or low-pass filter with 3dB point frequency.
+ The filter can be either single-pole (with -1), or double-pole
+ (the default, or with -2). width applies only to double-pole
+ filters; the default is Q = 0.707 and gives a Butterworth
+ response. The filters roll off at 6dB per pole per octave (20dB
+ per pole per decade). The double-pole filters are described in
+ detail in [1].
+
+ These effects support the --plot global option.
+
+ See also sinc for filters with a steeper roll-off.
+
+ hilbert [-n taps]
+ Apply an odd-tap Hilbert transform filter, phase-shifting the
+ signal by 90 degrees.
+
+ This is used in many matrix coding schemes and for analytic sig‐
+ nal generation. The process is often written as a multiplica‐
+ tion by i (or j), the imaginary unit.
+
+ An odd-tap Hilbert transform filter has a bandpass characteris‐
+ tic, attenuating the lowest and highest frequencies. Its band‐
+ width can be controlled by the number of filter taps, which can
+ be specified with -n. By default, the number of taps is chosen
+ for a cutoff frequency of about 75 Hz.
+
+ This effect supports the --plot global option.
+
+ ladspa [-l|-r] module [plugin] [argument ...]
+ Apply a LADSPA [5] (Linux Audio Developer's Simple Plugin API)
+ plugin. Despite the name, LADSPA is not Linux-specific, and a
+ wide range of effects is available as LADSPA plugins, such as
+ cmt [6] (the Computer Music Toolkit) and Steve Harris's plugin
+ collection [7]. The first argument is the plugin module, the
+ second the name of the plugin (a module can contain more than
+ one plugin), and any other arguments are for the control ports
+ of the plugin. Missing arguments are supplied by default values
+ if possible.
+
+ Normally, the number of input ports of the plugin must match the
+ number of input channels, and the number of output ports deter‐
+ mines the output channel count. However, the -r (replicate)
+ option allows cloning a mono plugin to handle multi-channel
+ input.
+
+ Some plugins introduce latency which SoX may optionally compen‐
+ sate for. The -l (latency compensation) option automatically
+ compensates for latency as reported by the plugin via an output
+ control port named "latency".
+
+ If found, the environment variable LADSPA_PATH will be used as
+ search path for plugins.
+
+ loudness [gain [reference]]
+ Loudness control - similar to the gain effect, but provides
+ equalisation for the human auditory system. See
+ http://en.wikipedia.org/wiki/Loudness for a detailed description
+ of loudness. The gain is adjusted by the given gain parameter
+ (usually negative) and the signal equalised according to ISO 226
+ w.r.t. a reference level of 65dB, though an alternative refer‐
+ ence level may be given if the original audio has been equalised
+ for some other optimal level. A default gain of -10dB is used
+ if a gain value is not given.
+
+ See also the gain effect.
+
+ lowpass [-1|-2] frequency[k] [width[q|o|h|k]]
+ Apply a low-pass filter. See the description of the highpass
+ effect for details.
+
+ mcompand "attack1,decay1{,attack2,decay2}
+ [soft-knee-dB:]in-dB1[,out-dB1]{,in-dB2,out-dB2}
+ [gain [initial-volume-dB [delay]]]" {crossover-freq[k]
+ "attack1,..."}
+
+ The multi-band compander is similar to the single-band compander
+ but the audio is first divided into bands using Linkwitz-Riley
+ cross-over filters and a separately specifiable compander run on
+ each band. See the compand effect for the definition of its
+ parameters. Compand parameters are specified between double
+ quotes and the crossover frequency for that band is given by
+ crossover-freq; these can be repeated to create multiple bands.
+
+ For example, the following (one long) command shows how multi-
+ band companding is typically used in FM radio:
+ play track1.wav gain -3 sinc 8000- 29 100 mcompand \
+ "0.005,0.1 -47,-40,-34,-34,-17,-33" 100 \
+ "0.003,0.05 -47,-40,-34,-34,-17,-33" 400 \
+ "0.000625,0.0125 -47,-40,-34,-34,-15,-33" 1600 \
+ "0.0001,0.025 -47,-40,-34,-34,-31,-31,-0,-30" 6400 \
+ "0,0.025 -38,-31,-28,-28,-0,-25" \
+ gain 15 highpass 22 highpass 22 sinc -n 255 -b 16 -17500 \
+ gain 9 lowpass -1 17801
+ The audio file is played with a simulated FM radio sound (or
+ broadcast signal condition if the lowpass filter at the end is
+ skipped). Note that the pipeline is set up with US-style 75us
+ pre-emphasis.
+
+ See also compand for a single-band companding effect.
+
+ noiseprof [profile-file]
+ Calculate a profile of the audio for use in noise reduction.
+ See the description of the noisered effect for details.
+
+ noisered [profile-file [amount]]
+ Reduce noise in the audio signal by profiling and filtering.
+ This effect is moderately effective at removing consistent back‐
+ ground noise such as hiss or hum. To use it, first run SoX with
+ the noiseprof effect on a section of audio that ideally would
+ contain silence but in fact contains noise - such sections are
+ typically found at the beginning or the end of a recording.
+ noiseprof will write out a noise profile to profile-file, or to
+ stdout if no profile-file or if `-' is given. E.g.
+ sox speech.wav -n trim 0 1.5 noiseprof speech.noise-profile
+ To actually remove the noise, run SoX again, this time with the
+ noisered effect; noisered will reduce noise according to a noise
+ profile (which was generated by noiseprof), from profile-file,
+ or from stdin if no profile-file or if `-' is given. E.g.
+ sox speech.wav cleaned.wav noisered speech.noise-profile 0.3
+ How much noise should be removed is specified by amount-a number
+ between 0 and 1 with a default of 0.5. Higher numbers will
+ remove more noise but present a greater likelihood of removing
+ wanted components of the audio signal. Before replacing an
+ original recording with a noise-reduced version, experiment with
+ different amount values to find the optimal one for your audio;
+ use headphones to check that you are happy with the results,
+ paying particular attention to quieter sections of the audio.
+
+ On most systems, the two stages - profiling and reduction - can
+ be combined using a pipe, e.g.
+ sox noisy.wav -n trim 0 1 noiseprof | play noisy.wav noisered
+
+ norm [dB-level]
+ Normalise the audio. norm is just an alias for gain -n; see the
+ gain effect for details.
+
+ oops Out Of Phase Stereo effect. Mixes stereo to twin-mono where
+ each mono channel contains the difference between the left and
+ right stereo channels. This is sometimes known as the `karaoke'
+ effect as it often has the effect of removing most or all of the
+ vocals from a recording. It is equivalent to remix 1,2i 1,2i.
+
+ overdrive [gain(20) [colour(20)]]
+ Non linear distortion. The colour parameter controls the amount
+ of even harmonic content in the over-driven output.
+
+ pad { length[@position(=)] }
+ Pad the audio with silence, at the beginning, the end, or any
+ specified points through the audio. length is the amount of
+ silence to insert and position the position in the input audio
+ stream at which to insert it. Any number of lengths and posi‐
+ tions may be specified, provided that a specified position is
+ not less that the previous one, and any time specification may
+ be used for them. position is optional for the first and last
+ lengths specified and if omitted correspond to the beginning and
+ the end of the audio respectively. For example, pad 1.5 1.5
+ adds 1.5 seconds of silence padding at each end of the audio,
+ whilst pad 4000s@3:00 inserts 4000 samples of silence 3 minutes
+ into the audio. If silence is wanted only at the end of the
+ audio, specify either the end position or specify a zero-length
+ pad at the start.
+
+ See also delay for an effect that can add silence at the begin‐
+ ning of the audio on a channel-by-channel basis.
+
+ phaser gain-in gain-out delay decay speed [-s|-t]
+ Add a phasing effect to the audio. See [3] for a detailed
+ description of phasing.
+
+ delay/decay/speed gives the delay in milliseconds and the decay
+ (relative to gain-in) with a modulation speed in Hz. The modu‐
+ lation is either sinusoidal (-s) - preferable for multiple
+ instruments, or triangular (-t) - gives single instruments a
+ sharper phasing effect. The decay should be less than 0.5 to
+ avoid feedback, and usually no less than 0.1. Gain-out is the
+ volume of the output.
+
+ For example:
+ play snare.flac phaser 0.8 0.74 3 0.4 0.5 -t
+ Gentler:
+ play snare.flac phaser 0.9 0.85 4 0.23 1.3 -s
+ A popular sound:
+ play snare.flac phaser 0.89 0.85 1 0.24 2 -t
+ More severe:
+ play snare.flac phaser 0.6 0.66 3 0.6 2 -t
+
+ pitch [-q] shift [segment [search [overlap]]]
+ Change the audio pitch (but not tempo).
+
+ shift gives the pitch shift as positive or negative `cents'
+ (i.e. 100ths of a semitone). See the tempo effect for a
+ description of the other parameters.
+
+ See also the bend, speed, and tempo effects.
+
+ rate [-q|-l|-m|-h|-v] [override-options] RATE[k]
+ Change the audio sampling rate (i.e. resample the audio) to any
+ given RATE (even non-integer if this is supported by the output
+ file format) using a quality level defined as follows:
+
+ Quality Band- Rej dB Typical Use
+ width
+ -q quick n/a ≈30 @ playback on
+ Fs/4 ancient hardware
+ -l low 80% 100 playback on old
+ hardware
+ -m medium 95% 100 audio playback
+
+
+ -h high 95% 125 16-bit mastering
+ (use with dither)
+ -v very high 95% 175 24-bit mastering
+
+ where Band-width is the percentage of the audio frequency band
+ that is preserved and Rej dB is the level of noise rejection.
+ Increasing levels of resampling quality come at the expense of
+ increasing amounts of time to process the audio. If no quality
+ option is given, the quality level used is `high' (but see
+ `Playing & Recording Audio' above regarding playback).
+
+ The `quick' algorithm uses cubic interpolation; all others use
+ band-limited interpolation. By default, all algorithms have a
+ `linear' phase response; for `medium', `high' and `very high',
+ the phase response is configurable (see below).
+
+ The rate effect is invoked automatically if SoX's -r option
+ specifies a rate that is different to that of the input file(s).
+ Alternatively, if this effect is given explicitly, then SoX's -r
+ option need not be given. For example, the following two com‐
+ mands are equivalent:
+ sox input.wav -r 48k output.wav bass -b 24
+ sox input.wav output.wav bass -b 24 rate 48k
+ though the second command is more flexible as it allows rate
+ options to be given, and allows the effects to be ordered arbi‐
+ trarily.
+
+ * * *
+
+ Warning: technically detailed discussion follows.
+
+ The simple quality selection described above provides settings
+ that satisfy the needs of the vast majority of resampling tasks.
+ Occasionally, however, it may be desirable to fine-tune the
+ resampler's filter response; this can be achieved using over‐
+ ride options, as detailed in the following table:
+
+ -M/-I/-L Phase response = minimum/intermediate/linear
+ -s Steep filter (band-width = 99%)
+ -a Allow aliasing/imaging above the pass-band
+ -b 74-99.7 Any band-width %
+ -p 0-100 Any phase response (0 = minimum, 25 = intermediate,
+ 50 = linear, 100 = maximum)
+
+ N.B. Override options cannot be used with the `quick' or `low'
+ quality algorithms.
+
+ All resamplers use filters that can sometimes create `echo'
+ (a.k.a. `ringing') artefacts with transient signals such as
+ those that occur with `finger snaps' or other highly percussive
+ sounds. Such artefacts are much more noticeable to the human
+ ear if they occur before the transient (`pre-echo') than if they
+ occur after it (`post-echo'). Note that frequency of any such
+ artefacts is related to the smaller of the original and new sam‐
+ pling rates but that if this is at least 44.1kHz, then the arte‐
+ facts will lie outside the range of human hearing.
+
+ A phase response setting may be used to control the distribution
+ of any transient echo between `pre' and `post': with minimum
+ phase, there is no pre-echo but the longest post-echo; with lin‐
+ ear phase, pre and post echo are in equal amounts (in signal
+ terms, but not audibility terms); the intermediate phase setting
+ attempts to find the best compromise by selecting a small length
+ (and level) of pre-echo and a medium lengthed post-echo.
+
+ Minimum, intermediate, or linear phase response is selected
+ using the -M, -I, or -L option; a custom phase response can be
+ created with the -p option. Note that phase responses between
+ `linear' and `maximum' (greater than 50) are rarely useful.
+
+ A resampler's band-width setting determines how much of the fre‐
+ quency content of the original signal (w.r.t. the original sam‐
+ ple rate when up-sampling, or the new sample rate when down-sam‐
+ pling) is preserved during conversion. The term `pass-band' is
+ used to refer to all frequencies up to the band-width point
+ (e.g. for 44.1kHz sampling rate, and a resampling band-width of
+ 95%, the pass-band represents frequencies from 0Hz (D.C.) to
+ circa 21kHz). Increasing the resampler's band-width results in
+ a slower conversion and can increase transient echo artefacts
+ (and vice versa).
+
+ The -s `steep filter' option changes resampling band-width from
+ the default 95% (based on the 3dB point), to 99%. The -b option
+ allows the band-width to be set to any value in the range
+ 74-99.7 %, but note that band-width values greater than 99% are
+ not recommended for normal use as they can cause excessive tran‐
+ sient echo.
+
+ If the -a option is given, then aliasing/imaging above the pass-
+ band is allowed. For example, with 44.1kHz sampling rate, and a
+ resampling band-width of 95%, this means that frequency content
+ above 21kHz can be distorted; however, since this is above the
+ pass-band (i.e. above the highest frequency of interest/audi‐
+ bility), this may not be a problem. The benefits of allowing
+ aliasing/imaging are reduced processing time, and reduced (by
+ almost half) transient echo artefacts. Note that if this option
+ is given, then the minimum band-width allowable with -b
+ increases to 85%.
+
+ Examples:
+ sox input.wav -b 16 output.wav rate -s -a 44100 dither -s
+ default (high) quality resampling; overrides: steep filter,
+ allow aliasing; to 44.1kHz sample rate; noise-shaped dither to
+ 16-bit WAV file.
+ sox input.wav -b 24 output.aiff rate -v -I -b 90 48k
+ very high quality resampling; overrides: intermediate phase,
+ band-width 90%; to 48k sample rate; store output to 24-bit AIFF
+ file.

+ The pitch and speed effects use the rate effect at their core.
+
+ remix [-a|-m|-p] <out-spec>
+ out-spec = in-spec{,in-spec} | 0
+ in-spec = [in-chan][-[in-chan2]][vol-spec]
+ vol-spec = p|i|v[volume]
+
+ Select and mix input audio channels into output audio channels.
+ Each output channel is specified, in turn, by a given out-spec:
+ a list of contributing input channels and volume specifications.
+
+ Note that this effect operates on the audio channels within the
+ SoX effects processing chain; it should not be confused with the
+ -m global option (where multiple files are mix-combined before
+ entering the effects chain).
+
+ An out-spec contains comma-separated input channel-numbers and
+ hyphen-delimited channel-number ranges; alternatively, 0 may be
+ given to create a silent output channel. For example,
+ sox input.wav output.wav remix 6 7 8 0
+ creates an output file with four channels, where channels 1, 2,
+ and 3 are copies of channels 6, 7, and 8 in the input file, and
+ channel 4 is silent. Whereas
+ sox input.wav output.wav remix 1-3,7 3
+ creates a (somewhat bizarre) stereo output file where the left
+ channel is a mix-down of input channels 1, 2, 3, and 7, and the
+ right channel is a copy of input channel 3.
+
+ Where a range of channels is specified, the channel numbers to
+ the left and right of the hyphen are optional and default to 1
+ and to the number of input channels respectively. Thus
+ sox input.wav output.wav remix -
+ performs a mix-down of all input channels to mono.
+
+ By default, where an output channel is mixed from multiple (n)
+ input channels, each input channel will be scaled by a factor of
+ ¹/n. Custom mixing volumes can be set by following a given
+ input channel or range of input channels with a vol-spec (volume
+ specification). This is one of the letters p, i, or v, followed
+ by a volume number, the meaning of which depends on the given
+ letter and is defined as follows:
+
+ Letter Volume number Notes
+ p power adjust in dB 0 = no change
+
+ i power adjust in dB As `p', but invert
+ the audio
+ v voltage multiplier 1 = no change, 0.5
+ ≈ 6dB attenuation,
+ 2 ≈ 6dB gain, -1 =
+ invert
+
+ If an out-spec includes at least one vol-spec then, by default,
+ ¹/n scaling is not applied to any other channels in the same
+ out-spec (though may be in other out-specs). The -a (automatic)
+ option however, can be given to retain the automatic scaling in
+ this case. For example,
+ sox input.wav output.wav remix 1,2 3,4v0.8
+ results in channel level multipliers of 0.5,0.5 1,0.8, whereas
+ sox input.wav output.wav remix -a 1,2 3,4v0.8
+ results in channel level multipliers of 0.5,0.5 0.5,0.8.
+
+ The -m (manual) option disables all automatic volume adjust‐
+ ments, so
+ sox input.wav output.wav remix -m 1,2 3,4v0.8
+ results in channel level multipliers of 1,1 1,0.8.
+
+ The volume number is optional and omitting it corresponds to no
+ volume change; however, the only case in which this is useful is
+ in conjunction with i. For example, if input.wav is stereo,
+ then
+ sox input.wav output.wav remix 1,2i
+ is a mono equivalent of the oops effect.
+
+ If the -p option is given, then any automatic ¹/n scaling is
+ replaced by ¹/√n (`power') scaling; this gives a louder mix but
+ one that might occasionally clip.
+
+ * * *
+
+ One use of the remix effect is to split an audio file into a set
+ of files, each containing one of the constituent channels (in
+ order to perform subsequent processing on individual audio chan‐
+ nels). Where more than a few channels are involved, a script
+ such as the following (Bourne shell script) is useful:
+ #!/bin/sh
+ chans=`soxi -c "$1"`
+ while [ $chans -ge 1 ]; do
+ chans0=`printf %02i $chans` # 2 digits hence up to 99 chans
+ out=`echo "$1"|sed "s/\(.*\)\.\(.*\)/\1-$chans0.\2/"`
+ sox "$1" "$out" remix $chans
+ chans=`expr $chans - 1`
+ done
+ If a file input.wav containing six audio channels were given,
+ the script would produce six output files: input-01.wav,
+ input-02.wav, ..., input-06.wav.
+
+ See also the swap effect.
+
+ repeat [count(1)|-]
+ Repeat the entire audio count times, or once if count is not
+ given. The special value - requests infinite repetition.
+ Requires temporary file space to store the audio to be repeated.
+ Note that repeating once yields two copies: the original audio
+ and the repeated audio.
+
+ reverb [-w|--wet-only] [reverberance (50%) [HF-damping (50%)
+ [room-scale (100%) [stereo-depth (100%)
+ [pre-delay (0ms) [wet-gain (0dB)]]]]]]
+
+ Add reverberation to the audio using the `freeverb' algorithm.
+ A reverberation effect is sometimes desirable for concert halls
+ that are too small or contain so many people that the hall's
+ natural reverberance is diminished. Applying a small amount of
+ stereo reverb to a (dry) mono signal will usually make it sound
+ more natural. See [3] for a detailed description of reverbera‐
+ tion.
+
+ Note that this effect increases both the volume and the length
+ of the audio, so to prevent clipping in these domains, a typical
+ invocation might be:
+ play dry.wav gain -3 pad 0 3 reverb
+ The -w option can be given to select only the `wet' signal, thus
+ allowing it to be processed further, independently of the `dry'
+ signal. E.g.
+ play -m voice.wav "|sox voice.wav -p reverse reverb -w reverse"
+ for a reverse reverb effect.
+
+ reverse
+ Reverse the audio completely. Requires temporary file space to
+ store the audio to be reversed.
+
+ riaa Apply RIAA vinyl playback equalisation. The sampling rate must
+ be one of: 44.1, 48, 88.2, 96 kHz.
+
+ This effect supports the --plot global option.
+
+ silence [-l] above-periods [duration threshold[d|%]
+ [below-periods duration threshold[d|%]]
+
+ Removes silence from the beginning, middle, or end of the audio.
+ `Silence' is determined by a specified threshold.
+
+ The above-periods value is used to indicate if audio should be
+ trimmed at the beginning of the audio. A value of zero indicates
+ no silence should be trimmed from the beginning. When specifying
+ a non-zero above-periods, it trims audio up until it finds non-
+ silence. Normally, when trimming silence from beginning of audio
+ the above-periods will be 1 but it can be increased to higher
+ values to trim all audio up to a specific count of non-silence
+ periods. For example, if you had an audio file with two songs
+ that each contained 2 seconds of silence before the song, you
+ could specify an above-period of 2 to strip out both silence
+ periods and the first song.
+
+ When above-periods is non-zero, you must also specify a duration
+ and threshold. duration indicates the amount of time that non-
+ silence must be detected before it stops trimming audio. By
+ increasing the duration, burst of noise can be treated as
+ silence and trimmed off.
+
+ threshold is used to indicate what sample value you should treat
+ as silence. For digital audio, a value of 0 may be fine but for
+ audio recorded from analog, you may wish to increase the value
+ to account for background noise.
+
+ When optionally trimming silence from the end of the audio, you
+ specify a below-periods count. In this case, below-period means
+ to remove all audio after silence is detected. Normally, this
+ will be a value 1 of but it can be increased to skip over peri‐
+ ods of silence that are wanted. For example, if you have a song
+ with 2 seconds of silence in the middle and 2 second at the end,
+ you could set below-period to a value of 2 to skip over the
+ silence in the middle of the audio.
+
+ For below-periods, duration specifies a period of silence that
+ must exist before audio is not copied any more. By specifying a
+ higher duration, silence that is wanted can be left in the
+ audio. For example, if you have a song with an expected 1 sec‐
+ ond of silence in the middle and 2 seconds of silence at the
+ end, a duration of 2 seconds could be used to skip over the mid‐
+ dle silence.
+
+ Unfortunately, you must know the length of the silence at the
+ end of your audio file to trim off silence reliably. A work‐
+ around is to use the silence effect in combination with the
+ reverse effect. By first reversing the audio, you can use the
+ above-periods to reliably trim all audio from what looks like
+ the front of the file. Then reverse the file again to get back
+ to normal.
+
+ To remove silence from the middle of a file, specify a below-
+ periods that is negative. This value is then treated as a posi‐
+ tive value and is also used to indicate that the effect should
+ restart processing as specified by the above-periods, making it
+ suitable for removing periods of silence in the middle of the
+ audio.
+
+ The option -l indicates that below-periods duration length of
+ audio should be left intact at the beginning of each period of
+ silence. For example, if you want to remove long pauses between
+ words but do not want to remove the pauses completely.
+
+ duration is a time specification with the peculiarity that a
+ bare number is interpreted as a sample count, not as a number of
+ seconds. For specifying seconds, either use the t suffix (as in
+ `2t') or specify minutes, too (as in `0:02').
+
+ threshold numbers may be suffixed with d to indicate the value
+ is in decibels, or % to indicate a percentage of maximum value
+ of the sample value (0% specifies pure digital silence).
+
+ The following example shows how this effect can be used to start
+ a recording that does not contain the delay at the start which
+ usually occurs between `pressing the record button' and the
+ start of the performance:
+ rec parameters filename other-effects silence 1 5 2%
+
+ sinc [-a att|-b beta] [-p phase|-M|-I|-L] [-t tbw|-n taps] [freqHP]
+ [-freqLP [-t tbw|-n taps]]
+ Apply a sinc kaiser-windowed low-pass, high-pass, band-pass, or
+ band-reject filter to the signal. The freqHP and freqLP parame‐
+ ters give the frequencies of the 6dB points of a high-pass and
+ low-pass filter that may be invoked individually, or together.
+ If both are given, then freqHP less than freqLP creates a band-
+ pass filter, freqHP greater than freqLP creates a band-reject
+ filter. For example, the invocations
+ sinc 3k
+ sinc -4k
+ sinc 3k-4k
+ sinc 4k-3k
+ create a high-pass, low-pass, band-pass, and band-reject filter
+ respectively.
+
+ The default stop-band attenuation of 120dB can be overridden
+ with -a; alternatively, the kaiser-window `beta' parameter can
+ be given directly with -b.
+
+ The default transition band-width of 5% of the total band can be
+ overridden with -t (and tbw in Hertz); alternatively, the number
+ of filter taps can be given directly with -n.
+
+ If both freqHP and freqLP are given, then a -t or -n option
+ given to the left of the frequencies applies to both frequen‐
+ cies; one of these options given to the right of the frequencies
+ applies only to freqLP.
+
+ The -p, -M, -I, and -L options control the filter's phase
+ response; see the rate effect for details.
+
+ This effect supports the --plot global option.
+
+ spectrogram [options]
+ Create a spectrogram of the audio; the audio is passed unmodi‐
+ fied through the SoX processing chain. This effect is optional
+ - type sox --help and check the list of supported effects to see
+ if it has been included.
+
+ The spectrogram is rendered in a Portable Network Graphic (PNG)
+ file, and shows time in the X-axis, frequency in the Y-axis, and
+ audio signal magnitude in the Z-axis. Z-axis values are repre‐
+ sented by the colour (or optionally the intensity) of the pixels
+ in the X-Y plane. If the audio signal contains multiple chan‐
+ nels then these are shown from top to bottom starting from chan‐
+ nel 1 (which is the left channel for stereo audio).
+
+ For example, if `my.wav' is a stereo file, then with
+ sox my.wav -n spectrogram
+ a spectrogram of the entire file will be created in the file
+ `spectrogram.png'. More often though, analysis of a smaller
+ portion of the audio is required; e.g. with
+ sox my.wav -n remix 2 trim 20 30 spectrogram
+ the spectrogram shows information only from the second (right)
+ channel, and of thirty seconds of audio starting from twenty
+ seconds in. To analyse a small portion of the frequency domain,
+ the rate effect may be used, e.g.
+ sox my.wav -n rate 6k spectrogram
+ allows detailed analysis of frequencies up to 3kHz (half the
+ sampling rate) i.e. where the human auditory system is most sen‐
+ sitive. With
+ sox my.wav -n trim 0 10 spectrogram -x 600 -y 200 -z 100
+ the given options control the size of the spectrogram's X, Y & Z
+ axes (in this case, the spectrogram area of the produced image
+ will be 600 by 200 pixels in size and the Z-axis range will be
+ 100 dB). Note that the produced image includes axes legends
+ etc. and so will be a little larger than the specified spectro‐
+ gram size. In this example:
+ sox -n -n synth 6 tri 10k:14k spectrogram -z 100 -w kaiser
+ an analysis `window' with high dynamic range is selected to best
+ display the spectrogram of a swept triangular wave. For a smi‐
+ lar example, append the following to the `chime' command in the
+ description of the delay effect (above):
+ rate 2k spectrogram -X 200 -Z -10 -w kaiser
+ Options are also available to control the appearance (colour-
+ set, brightness, contrast, etc.) and filename of the spectro‐
+ gram; e.g. with
+ sox my.wav -n spectrogram -m -l -o print.png
+ a spectrogram is created suitable for printing on a `black and
+ white' printer.
+
+ Options:
+
+ -x num Change the (maximum) width (X-axis) of the spectrogram
+ from its default value of 800 pixels to a given number
+ between 100 and 200000. See also -X and -d.
+
+ -X num X-axis pixels/second; the default is auto-calculated to
+ fit the given or known audio duration to the X-axis size,
+ or 100 otherwise. If given in conjunction with -d, this
+ option affects the width of the spectrogram; otherwise,
+ it affects the duration of the spectrogram. num can be
+ from 1 (low time resolution) to 5000 (high time resolu‐
+ tion) and need not be an integer. SoX may make a slight
+ adjustment to the given number for processing quantisa‐
+ tion reasons; if so, SoX will report the actual number
+ used (viewable when the SoX global option -V is in
+ effect). See also -x and -d.
+
+ -y num Sets the Y-axis size in pixels (per channel); this is the
+ number of frequency `bins' used in the Fourier analysis
+ that produces the spectrogram. N.B. it can be slow to
+ produce the spectrogram if this number is not one more
+ than a power of two (e.g. 129). By default the Y-axis
+ size is chosen automatically (depending on the number of
+ channels). See -Y for alternative way of setting spec‐
+ trogram height.
+
+ -Y num Sets the target total height of the spectrogram(s). The
+ default value is 550 pixels. Using this option (and by
+ default), SoX will choose a height for individual spec‐
+ trogram channels that is one more than a power of two, so
+ the actual total height may fall short of the given num‐
+ ber. However, there is also a minimum height per channel
+ so if there are many channels, the number may be
+ exceeded. See -y for alternative way of setting spectro‐
+ gram height.
+
+ -z num Z-axis (colour) range in dB, default 120. This sets the
+ dynamic-range of the spectrogram to be -num dBFS to
+ 0 dBFS. Num may range from 20 to 180. Decreasing
+ dynamic-range effectively increases the `contrast' of the
+ spectrogram display, and vice versa.
+
+ -Z num Sets the upper limit of the Z-axis in dBFS. A negative
+ num effectively increases the `brightness' of the spec‐
+ trogram display, and vice versa.
+
+ -q num Sets the Z-axis quantisation, i.e. the number of differ‐
+ ent colours (or intensities) in which to render Z-axis
+ values. A small number (e.g. 4) will give a
+ `poster'-like effect making it easier to discern magni‐
+ tude bands of similar level. Small numbers also usually
+ result in small PNG files. The number given specifies
+ the number of colours to use inside the Z-axis range; two
+ colours are reserved to represent out-of-range values.
+
+ -w name
+ Window: Hann (default), Hamming, Bartlett, Rectangular,
+ Kaiser or Dolph. The spectrogram is produced using the
+ Discrete Fourier Transform (DFT) algorithm. A signifi‐
+ cant parameter to this algorithm is the choice of `window
+ function'. By default, SoX uses the Hann window which
+ has good all-round frequency-resolution and dynamic-range
+ properties. For better frequency resolution (but lower
+ dynamic-range), select a Hamming window; for higher
+ dynamic-range (but poorer frequency-resolution), select a
+ Dolph window. Kaiser, Bartlett and Rectangular windows
+ are also available.
+
+ -W num Window adjustment parameter. This can be used to make
+ small adjustments to the Kaiser or Dolph window shape. A
+ positive number (up to ten) increases its dynamic range,
+ a negative number decreases it.
+
+ -s Allow slack overlapping of DFT windows. This can, in
+ some cases, increase image sharpness and give greater
+ adherence to the -x value, but at the expense of a little
+ spectral loss.
+
+ -m Creates a monochrome spectrogram (the default is colour).
+
+ -h Selects a high-colour palette - less visually pleasing
+ than the default colour palette, but it may make it eas‐
+ ier to differentiate different levels. If this option is
+ used in conjunction with -m, the result will be a hybrid
+ monochrome/colour palette.
+
+ -p num Permute the colours in a colour or hybrid palette. The
+ num parameter, from 1 (the default) to 6, selects the
+ permutation.
+
+ -l Creates a `printer friendly' spectrogram with a light
+ background (the default has a dark background).
+
+ -a Suppress the display of the axis lines. This is some‐
+ times useful in helping to discern artefacts at the spec‐
+ trogram edges.
+
+ -r Raw spectrogram: suppress the display of axes and leg‐
+ ends.
+
+ -A Selects an alternative, fixed colour-set. This is pro‐
+ vided only for compatibility with spectrograms produced
+ by another package. It should not normally be used as it
+ has some problems, not least, a lack of differentiation
+ at the bottom end which results in masking of low-level
+ artefacts.
+
+ -t text
+ Set the image title - text to display above the spectro‐
+ gram.
+
+ -c text
+ Set (or clear) the image comment - text to display below
+ and to the left of the spectrogram.
+
+ -o file
+ Name of the spectrogram output PNG file, default `spec‐
+ trogram.png'. If `-' is given, the spectrogram will be
+ sent to standard output (stdout).
+
+ Advanced Options:
+ In order to process a smaller section of audio without affecting
+ other effects or the output signal (unlike when the trim effect
+ is used), the following options may be used.
+
+ -d duration
+ This option sets the X-axis resolution such that audio
+ with the given duration (a time specification) fits the
+ selected (or default) X-axis width. For example,
+ sox input.mp3 output.wav -n spectrogram -d 1:00 stats
+ creates a spectrogram showing the first minute of the
+ audio, whilst
+ the stats effect is applied to the entire audio signal.
+
+ See also -X for an alternative way of setting the X-axis
+ resolution.
+
+ -S position(=)
+ Start the spectrogram at the given point in the audio
+ stream. For example
+ sox input.aiff output.wav spectrogram -S 1:00
+ creates a spectrogram showing all but the first minute of
+ the audio (the output file, however, receives the entire
+ audio stream).
+
+ For the ability to perform off-line processing of spectral data,
+ see the stat effect.
+
+ speed factor[c]
+ Adjust the audio speed (pitch and tempo together). factor is
+ either the ratio of the new speed to the old speed: greater than
+ 1 speeds up, less than 1 slows down, or, if appended with the
+ letter `c', the number of cents (i.e. 100ths of a semitone) by
+ which the pitch (and tempo) should be adjusted: greater than 0
+ increases, less than 0 decreases.
+
+ Technically, the speed effect only changes the sample rate
+ information, leaving the samples themselves untouched. The rate
+ effect is invoked automatically to resample to the output sample
+ rate, using its default quality/speed. For higher quality or
+ higher speed resampling, in addition to the speed effect, spec‐
+ ify the rate effect with the desired quality option.
+
+ See also the bend, pitch, and tempo effects.
+
+ splice [-h|-t|-q] { position(=)[,excess[,leeway]] }
+ Splice together audio sections. This effect provides two things
+ over simple audio concatenation: a (usually short) cross-fade is
+ applied at the join, and a wave similarity comparison is made to
+ help determine the best place at which to make the join.
+
+ One of the options -h, -t, or -q may be given to select the fade
+ envelope as half-cosine wave (the default), triangular (a.k.a.
+ linear), or quarter-cosine wave respectively.
+
+ Type Audio Fade level Transitions
+ t correlated constant gain abrupt
+ h correlated constant gain smooth
+ q uncorrelated constant power smooth
+
+ To perform a splice, first use the trim effect to select the
+ audio sections to be joined together. As when performing a tape
+ splice, the end of the section to be spliced onto should be
+ trimmed with a small excess (default 0.005 seconds) of audio
+ after the ideal joining point. The beginning of the audio sec‐
+ tion to splice on should be trimmed with the same excess (before
+ the ideal joining point), plus an additional leeway (default
+ 0.005 seconds). Any time specification may be used for these
+ parameters. SoX should then be invoked with the two audio sec‐
+ tions as input files and the splice effect given with the posi‐
+ tion at which to perform the splice - this is length of the
+ first audio section (including the excess).
+
+ The following diagram uses the tape analogy to illustrate the
+ splice operation. The effect simulates the diagonal cuts and
+ joins the two pieces:
+
+ length1 excess

+ excess leeway
+
+ where * indicates the joining points.
+
+ For example, a long song begins with two verses which start (as
+ determined e.g. by using the play command with the trim (start)
+ effect) at times 0:30.125 and 1:03.432. The following commands
+ cut out the first verse:
+ sox too-long.wav part1.wav trim 0 30.130
+ (5 ms excess, after the first verse starts)
+ sox too-long.wav part2.wav trim 1:03.422
+ (5 ms excess plus 5 ms leeway, before the second verse starts)
+ sox part1.wav part2.wav just-right.wav splice 30.130
+ For another example, the SoX command
+ play "|sox -n -p synth 1 sin %1" "|sox -n -p synth 1 sin %3"
+ generates and plays two notes, but there is a nasty click at the
+ transition; the click can be removed by splicing instead of con‐
+ catenating the audio, i.e. by appending splice 1 to the command.
+ (Clicks at the beginning and end of the audio can be removed by
+ preceding the splice effect with fade q .01 2 .01).
+
+ Provided your arithmetic is good enough, multiple splices can be
+ performed with a single splice invocation. For example:
+ #!/bin/sh
+ # Audio Copy and Paste Over
+ # acpo infile copy-start copy-stop paste-over-start outfile
+ # No chained time specifications allowed for the parameters
+ # (i.e. such that contain +/-).
+ e=0.005 # Using default excess
+ l=$e # and leeway.
+ sox "$1" piece.wav trim $2-$e-$l =$3+$e
+ sox "$1" part1.wav trim 0 $4+$e
+ sox "$1" part2.wav trim $4+$3-$2-$e-$l
+ sox part1.wav piece.wav part2.wav "$5" \
+ splice $4+$e +$3-$2+$e+$l+$e
+ In the above Bourne shell script, two splices are used to `copy
+ and paste' audio.
+
+ * * *
+
+ It is also possible to use this effect to perform general cross-
+ fades, e.g. to join two songs. In this case, excess would typi‐
+ cally be an number of seconds, the -q option would typically be
+ given (to select an `equal power' cross-fade), and leeway should
+ be zero (which is the default if -q is given). For example, if
+ f1.wav and f2.wav are audio files to be cross-faded, then
+ sox f1.wav f2.wav out.wav splice -q $(soxi -D f1.wav),3
+ cross-fades the files where the point of equal loudness is 3
+ seconds before the end of f1.wav, i.e. the total length of the
+ cross-fade is 2 × 3 = 6 seconds (Note: the $(...) notation is
+ POSIX shell).
+
+ stat [-s scale] [-rms] [-freq] [-v] [-d]
+ Display time and frequency domain statistical information about
+ the audio. Audio is passed unmodified through the SoX process‐
+ ing chain.
+
+ The information is output to the `standard error' (stderr)
+ stream and is calculated, where n is the duration of the audio
+ in samples, c is the number of audio channels, r is the audio
+ sample rate, and xk represents the PCM value (in the range -1 to
+ +1 by default) of each successive sample in the audio, as fol‐
+ lows:
+
+ Samples read n×c
+ Length (seconds) n÷r
+ Scaled by See -s below.
+ Maximum amplitude max(xk) The maximum sample
+ value in the audio;
+ usually this will
+ be a positive num‐
+ ber.
+ Minimum amplitude min(xk) The minimum sample
+ value in the audio;
+ usually this will
+ be a negative num‐
+ ber.
+ Midline amplitude ½min(xk)+½max(xk)
+ Mean norm ¹/nΣ│xk│ The average of the
+ absolute value of
+ each sample in the
+ audio.
+ Mean amplitude ¹/nΣxk The average of each
+ sample in the
+ audio. If this
+ figure is non-zero,
+ then it indicates
+ the presence of a
+ D.C. offset (which
+ could be removed
+ using the dcshift
+ effect).
+
+
+
+ RMS amplitude √(¹/nΣxk²) The level of a D.C.
+ signal that would
+ have the same power
+ as the audio's
+ average power.
+ Maximum delta max(│xk-xk-1│)
+ Minimum delta min(│xk-xk-1│)
+ Mean delta ¹/n-1Σ│xk-xk-1│
+ RMS delta √(¹/n-1Σ(xk-xk-1)²)
+ Rough frequency In Hz.
+ Volume Adjustment The parameter to
+ the vol effect
+ which would make
+ the audio as loud
+ as possible without
+ clipping. Note:
+ See the discussion
+ on Clipping above
+ for reasons why it
+ is rarely a good
+ idea actually to do
+ this.
+
+ Note that the delta measurements are not applicable for multi-
+ channel audio.
+
+ The -s option can be used to scale the input data by a given
+ factor. The default value of scale is 2147483647 (i.e. the max‐
+ imum value of a 32-bit signed integer). Internal effects always
+ work with signed long PCM data and so the value should relate to
+ this fact.
+
+ The -rms option will convert all output average values to `root
+ mean square' format.
+
+ The -v option displays only the `Volume Adjustment' value.
+
+ The -freq option calculates the input's power spectrum (4096
+ point DFT) instead of the statistics listed above. This should
+ only be used with a single channel audio file.
+
+ The -d option displays a hex dump of the 32-bit signed PCM data
+ audio in SoX's internal buffer. This is mainly used to help
+ track down endian problems that sometimes occur in cross-plat‐
+ form versions of SoX.
+
+ See also the stats effect.
+
+ stats [-b bits|-x bits|-s scale] [-w window-time]
+ Display time domain statistical information about the audio
+ channels; audio is passed unmodified through the SoX processing
+ chain. Statistics are calculated and displayed for each audio
+ channel and, where applicable, an overall figure is also given.
+
+ For example, for a typical well-mastered stereo music file:
+
+ Overall Left Right
+ DC offset 0.000803 -0.000391 0.000803
+ Min level -0.750977 -0.750977 -0.653412
+ Max level 0.708801 0.708801 0.653534
+ Pk lev dB -2.49 -2.49 -3.69
+ RMS lev dB -19.41 -19.13 -19.71
+ RMS Pk dB -13.82 -13.82 -14.38
+ RMS Tr dB -85.25 -85.25 -82.66
+ Crest factor - 6.79 6.32
+ Flat factor 0.00 0.00 0.00
+ Pk count 2 2 2
+ Bit-depth 16/16 16/16 16/16
+ Num samples 7.72M
+ Length s 174.973
+ Scale max 1.000000
+ Window s 0.050
+
+ DC offset, Min level, and Max level are shown, by default, in
+ the range ±1. If the -b (bits) options is given, then these
+ three measurements will be scaled to a signed integer with the
+ given number of bits; for example, for 16 bits, the scale would
+ be -32768 to +32767. The -x option behaves the same way as -b
+ except that the signed integer values are displayed in hexadeci‐
+ mal. The -s option scales the three measurements by a given
+ floating-point number.
+
+ Pk lev dB and RMS lev dB are standard peak and RMS level mea‐
+ sured in dBFS. RMS Pk dB and RMS Tr dB are peak and trough val‐
+ ues for RMS level measured over a short window (default 50ms).
+
+ Crest factor is the standard ratio of peak to RMS level (note:
+ not in dB).
+
+ Flat factor is a measure of the flatness (i.e. consecutive sam‐
+ ples with the same value) of the signal at its peak levels (i.e.
+ either Min level, or Max level). Pk count is the number of
+ occasions (not the number of samples) that the signal attained
+ either Min level, or Max level.
+
+ The right-hand Bit-depth figure is the standard definition of
+ bit-depth i.e. bits less significant than the given number are
+ fixed at zero. The left-hand figure is the number of most sig‐
+ nificant bits that are fixed at zero (or one for negative num‐
+ bers) subtracted from the right-hand figure (the number sub‐
+ tracted is directly related to Pk lev dB).
+
+ For multi-channel audio, an overall figure for each of the above
+ measurements is given and derived from the channel figures as
+ follows: DC offset: maximum magnitude; Max level, Pk lev dB,
+ RMS Pk dB, Bit-depth: maximum; Min level, RMS Tr dB: minimum;
+ RMS lev dB, Flat factor, Pk count: average; Crest factor: not
+ applicable.
+
+ Length s is the duration in seconds of the audio, and Num sam‐
+ ples is equal to the sample-rate multiplied by Length.
+ Scale Max is the scaling applied to the first three measure‐
+ ments; specifically, it is the maximum value that could apply to
+ Max level. Window s is the length of the window used for the
+ peak and trough RMS measurements.
+
+ See also the stat effect.
+
+ swap Swap stereo channels. If the input is not stereo, pairs of
+ channels are swapped, and a possible odd last channel passed
+ through. E.g., for seven channels, the output order will be 2,
+ 1, 4, 3, 6, 5, 7.
+
+ See also remix for an effect that allows arbitrary channel
+ selection and ordering (and mixing).
+
+ stretch factor [window fade shift fading]
+ Change the audio duration (but not its pitch). This effect is
+ broadly equivalent to the tempo effect with (factor inverted
+ and) search set to zero, so in general, its results are compara‐
+ tively poor; it is retained as it can sometimes out-perform
+ tempo for small factors.
+
+ factor of stretching: >1 lengthen, <1 shorten duration. window
+ size is in ms. Default is 20ms. The fade option, can be `lin'.
+ shift ratio, in [0 1]. Default depends on stretch factor. 1 to
+ shorten, 0.8 to lengthen. The fading ratio, in [0 0.5]. The
+ amount of a fade's default depends on factor and shift.
+
+ See also the tempo effect.
+
+ synth [-j KEY] [-n] [len [off [ph [p1 [p2 [p3]]]]]] {[type] [combine]
+ [[%]freq[k][:|+|/|-[%]freq2[k]]] [off [ph [p1 [p2 [p3]]]]]}
+ This effect can be used to generate fixed or swept frequency
+ audio tones with various wave shapes, or to generate wide-band
+ noise of various `colours'. Multiple synth effects can be cas‐
+ caded to produce more complex waveforms; at each stage it is
+ possible to choose whether the generated waveform will be mixed
+ with, or modulated onto the output from the previous stage.
+ Audio for each channel in a multi-channel audio file can be syn‐
+ thesised independently.
+
+ Though this effect is used to generate audio, an input file must
+ still be given, the characteristics of which will be used to set
+ the synthesised audio length, the number of channels, and the
+ sampling rate; however, since the input file's audio is not nor‐
+ mally needed, a `null file' (with the special name -n) is often
+ given instead (and the length specified as a parameter to synth
+ or by another given effect that has an associated length).
+
+ For example, the following produces a 3 second, 48kHz, audio
+ file containing a sine-wave swept from 300 to 3300 Hz:
+ sox -n output.wav synth 3 sine 300-3300
+ and this produces an 8 kHz version:
+ sox -r 8000 -n output.wav synth 3 sine 300-3300
+ Multiple channels can be synthesised by specifying the set of
+ parameters shown between braces multiple times; the following
+ puts the swept tone in the left channel and adds `brown' noise
+ in the right:
+ sox -n output.wav synth 3 sine 300-3300 brownnoise
+ The following example shows how two synth effects can be cas‐
+ caded to create a more complex waveform:
+ play -n synth 0.5 sine 200-500 synth 0.5 sine fmod 700-100
+ Frequencies can also be given in `scientific' note notation, or,
+ by prefixing a `%' character, as a number of semitones relative
+ to `middle A' (440 Hz). For example, the following could be
+ used to help tune a guitar's low `E' string:
+ play -n synth 4 pluck %-29
+ or with a (Bourne shell) loop, the whole guitar:
+ for n in E2 A2 D3 G3 B3 E4; do
+ play -n synth 4 pluck $n repeat 2; done
+ See the delay effect (above) and the reference to `SoX scripting
+ examples' (below) for more synth examples.
+
+ N.B. This effect generates audio at maximum volume (0dBFS),
+ which means that there is a high chance of clipping when using
+ the audio subsequently, so in many cases, you will want to fol‐
+ low this effect with the gain effect to prevent this from hap‐
+ pening. (See also Clipping above.) Note that, by default, the
+ synth effect incorporates the functionality of gain -h (see the
+ gain effect for details); synth's -n option may be given to dis‐
+ able this behaviour.
+
+ A detailed description of each synth parameter follows:
+
+ len is the length of audio to synthesise (any time specifica‐
+ tion); a value of 0 indicated to use the input length, which is
+ also the default.
+
+ type is one of sine, square, triangle, sawtooth, trapezium, exp,
+ [white]noise, tpdfnoise, pinknoise, brownnoise, pluck;
+ default=sine.
+
+ combine is one of create, mix, amod (amplitude modulation), fmod
+ (frequency modulation); default=create.
+
+ freq/freq2 are the frequencies at the beginning/end of synthesis
+ in Hz or, if preceded with `%', semitones relative to A
+ (440 Hz); alternatively, `scientific' note notation (e.g. E2)
+ may be used. The default frequency is 440Hz. By default, the
+ tuning used with the note notations is `equal temperament'; the
+ -j KEY option selects `just intonation', where KEY is an integer
+ number of semitones relative to A (so for example, -9 or 3
+ selects the key of C), or a note in scientific notation.
+
+ If freq2 is given, then len must also have been given and the
+ generated tone will be swept between the given frequencies. The
+ two given frequencies must be separated by one of the characters
+ `:', `+', `/', or `-'. This character is used to specify the
+ sweep function as follows:
+
+ : Linear: the tone will change by a fixed number of hertz
+ per second.
+
+ + Square: a second-order function is used to change the
+ tone.
+
+ / Exponential: the tone will change by a fixed number of
+ semitones per second.
+
+ - Exponential: as `/', but initial phase always zero, and
+ stepped (less smooth) frequency changes.
+
+ Not used for noise.
+
+ off is the bias (DC-offset) of the signal in percent; default=0.
+
+ ph is the phase shift in percentage of 1 cycle; default=0. Not
+ used for noise.
+
+ p1 is the percentage of each cycle that is `on' (square), or
+ `rising' (triangle, exp, trapezium); default=50 (square, trian‐
+ gle, exp), default=10 (trapezium), or sustain (pluck);
+ default=40.
+
+ p2 (trapezium): the percentage through each cycle at which
+ `falling' begins; default=50. exp: the amplitude in multiples of
+ 2dB; default=50, or tone-1 (pluck); default=20.
+
+ p3 (trapezium): the percentage through each cycle at which
+ `falling' ends; default=60, or tone-2 (pluck); default=90.
+
+ tempo [-q] [-m|-s|-l] factor [segment [search [overlap]]]
+ Change the audio playback speed but not its pitch. This effect
+ uses the WSOLA algorithm. The audio is chopped up into segments
+ which are then shifted in the time domain and overlapped (cross-
+ faded) at points where their waveforms are most similar as
+ determined by measurement of `least squares'.
+
+ By default, linear searches are used to find the best overlap‐
+ ping points. If the optional -q parameter is given, tree
+ searches are used instead. This makes the effect work more
+ quickly, but the result may not sound as good. However, if you
+ must improve the processing speed, this generally reduces the
+ sound quality less than reducing the search or overlap values.
+
+ The -m option is used to optimize default values of segment,
+ search and overlap for music processing.
+
+ The -s option is used to optimize default values of segment,
+ search and overlap for speech processing.
+
+ The -l option is used to optimize default values of segment,
+ search and overlap for `linear' processing that tends to cause
+ more noticeable distortion but may be useful when factor is
+ close to 1.
+
+ If -m, -s, or -l is specified, the default value of segment will
+ be calculated based on factor, while default search and overlap
+ values are based on segment. Any values you provide still over‐
+ ride these default values.
+
+ factor gives the ratio of new tempo to the old tempo, so e.g.
+ 1.1 speeds up the tempo by 10%, and 0.9 slows it down by 10%.
+
+ The optional segment parameter selects the algorithm's segment
+ size in milliseconds. If no other flags are specified, the
+ default value is 82 and is typically suited to making small
+ changes to the tempo of music. For larger changes (e.g. a factor
+ of 2), 41 ms may give a better result. The -m, -s, and -l flags
+ will cause the segment default to be automatically adjusted
+ based on factor. For example using -s (for speech) with a tempo
+ of 1.25 will calculate a default segment value of 32.
+
+ The optional search parameter gives the audio length in mil‐
+ liseconds over which the algorithm will search for overlapping
+ points. If no other flags are specified, the default value is
+ 14.68. Larger values use more processing time and may or may
+ not produce better results. A practical maximum is half the
+ value of segment. Search can be reduced to cut processing time
+ at the risk of degrading output quality. The -m, -s, and -l
+ flags will cause the search default to be automatically adjusted
+ based on segment.
+
+ The optional overlap parameter gives the segment overlap length
+ in milliseconds. Default value is 12, but -m, -s, or -l flags
+ automatically adjust overlap based on segment size. Increasing
+ overlap increases processing time and may increase quality. A
+ practical maximum for overlap is the value of search, with over‐
+ lap typically being (at least) a little smaller then search.
+
+ See also speed for an effect that changes tempo and pitch
+ together, pitch and bend for effects that change pitch only, and
+ stretch for an effect that changes tempo using a different algo‐
+ rithm.
+
+ treble gain [frequency[k] [width[s|h|k|o|q]]]
+ Apply a treble tone-control effect. See the description of the
+ bass effect for details.
+
+ tremolo speed [depth]
+ Apply a tremolo (low frequency amplitude modulation) effect to
+ the audio. The tremolo frequency in Hz is given by speed, and
+ the depth as a percentage by depth (default 40).
+
+ trim {position(+)}
+ Cuts portions out of the audio. Any number of positions may be
+ given; audio is not sent to the output until the first position
+ is reached. The effect then alternates between copying and dis‐
+ carding audio at each position. Using a value of 0 for the
+ first position parameter allows copying from the beginning of
+ the audio.
+
+ For example,
+ sox infile outfile trim 0 10
+ will copy the first ten seconds, while
+ play infile trim 12:34 =15:00 -2:00
+ and
+ play infile trim 12:34 2:26 -2:00
+ will both play from 12 minutes 34 seconds into the audio up to
+ 15 minutes into the audio (i.e. 2 minutes and 26 seconds long),
+ then resume playing two minutes before the end of audio.
+
+ upsample [factor]
+ Upsample the signal by an integer factor: factor-1 zero-value
+ samples are inserted between each pair of input samples. As a
+ result, the original spectrum is replicated into the new fre‐
+ quency space (imaging) and attenuated. This attenuation can be
+ compensated for by adding vol factor after any further process‐
+ ing. The upsample effect is typically used in combination with
+ filtering effects.
+
+ For a general resampling effect with anti-imaging, see rate.
+ See also downsample.
+
+ vad [options]
+ Voice Activity Detector. Attempts to trim silence and quiet
+ background sounds from the ends of (fairly high resolution i.e.
+ 16-bit, 44-48kHz) recordings of speech. The algorithm currently
+ uses a simple cepstral power measurement to detect voice, so may
+ be fooled by other things, especially music. The effect can
+ trim only from the front of the audio, so in order to trim from
+ the back, the reverse effect must also be used. E.g.
+ play speech.wav norm vad
+ to trim from the front,
+ play speech.wav norm reverse vad reverse
+ to trim from the back, and
+ play speech.wav norm vad reverse vad reverse
+ to trim from both ends. The use of the norm effect is recom‐
+ mended, but remember that neither reverse nor norm is suitable
+ for use with streamed audio.
+
+ Options:
+ Default values are shown in parenthesis.
+
+ -t num (7)
+ The measurement level used to trigger activity detection.
+ This might need to be changed depending on the noise
+ level, signal level and other charactistics of the input
+ audio.
+
+ -T num (0.25)
+ The time constant (in seconds) used to help ignore short
+ bursts of sound.
+
+ -s num (1)
+ The amount of audio (in seconds) to search for qui‐
+ eter/shorter bursts of audio to include prior to the
+ detected trigger point.
+
+ -g num (0.25)
+ Allowed gap (in seconds) between quieter/shorter bursts
+ of audio to include prior to the detected trigger point.
+
+ -p num (0)
+ The amount of audio (in seconds) to preserve before the
+ trigger point and any found quieter/shorter bursts.
+
+ Advanced Options:
+ These allow fine tuning of the algorithm's internal parameters.
+
+ -b num The algorithm (internally) uses adaptive noise estima‐
+ tion/reduction in order to detect the start of the wanted
+ audio. This option sets the time for the initial noise
+ estimate.
+
+ -N num Time constant used by the adaptive noise estimator for
+ when the noise level is increasing.
+
+ -n num Time constant used by the adaptive noise estimator for
+ when the noise level is decreasing.
+
+ -r num Amount of noise reduction to use in the detection algo‐
+ rithm (e.g. 0, 0.5, ...).
+
+ -f num Frequency of the algorithm's processing/measurements.
+
+ -m num Measurement duration; by default, twice the measurement
+ period; i.e. with overlap.
+
+ -M num Time constant used to smooth spectral measurements.
+
+ -h num `Brick-wall' frequency of high-pass filter applied at the
+ input to the detector algorithm.
+
+ -l num `Brick-wall' frequency of low-pass filter applied at the
+ input to the detector algorithm.
+
+ -H num `Brick-wall' frequency of high-pass lifter used in the
+ detector algorithm.
+
+ -L num `Brick-wall' frequency of low-pass lifter used in the
+ detector algorithm.
+
+ See also the silence effect.
+
+ vol gain [type [limitergain]]
+ Apply an amplification or an attenuation to the audio signal.
+ Unlike the -v option (which is used for balancing multiple input
+ files as they enter the SoX effects processing chain), vol is an
+ effect like any other so can be applied anywhere, and several
+ times if necessary, during the processing chain.
+
+ The amount to change the volume is given by gain which is inter‐
+ preted, according to the given type, as follows: if type is
+ amplitude (or is omitted), then gain is an amplitude (i.e. volt‐
+ age or linear) ratio, if power, then a power (i.e. wattage or
+ voltage-squared) ratio, and if dB, then a power change in dB.
+
+ When type is amplitude or power, a gain of 1 leaves the volume
+ unchanged, less than 1 decreases it, and greater than 1
+ increases it; a negative gain inverts the audio signal in addi‐
+ tion to adjusting its volume.
+
+ When type is dB, a gain of 0 leaves the volume unchanged, less
+ than 0 decreases it, and greater than 0 increases it.
+
+ See [4] for a detailed discussion on electrical (and hence audio
+ signal) voltage and power ratios.
+
+ Beware of Clipping when the increasing the volume.
+
+ The gain and the type parameters can be concatenated if desired,
+ e.g. vol 10dB.
+
+ An optional limitergain value can be specified and should be a
+ value much less than 1 (e.g. 0.05 or 0.02) and is used only on
+ peaks to prevent clipping. Not specifying this parameter will
+ cause no limiter to be used. In verbose mode, this effect will
+ display the percentage of the audio that needed to be limited.
+
+ See also gain for a volume-changing effect with different capa‐
+ bilities, and compand for a dynamic-range compression/expan‐
+ sion/limiting effect.
+
+DIAGNOSTICS
+ Exit status is 0 for no error, 1 if there is a problem with the com‐
+ mand-line parameters, or 2 if an error occurs during file processing.

+.SH NAME
+SoX \- Sound eXchange, the Swiss Army knife of audio manipulation
+.SH DESCRIPTION
+This manual describes SoX supported file formats and audio device types;
+the SoX manual set starts with
+.BR sox (1).
+.SP
+Format types that can SoX can determine by a filename
+extension are listed with their names preceded by a dot.
+Format types that are optionally built into SoX
+are marked `(optional)'.
+.SP
+Format types that can be handled by an
+external library via an optional pseudo file type (currently
+.BR sndfile )
+are marked e.g. `(also with \fB\-t sndfile\fR)'. This might be
+useful if you have a file that doesn't work with SoX's default format
+readers and writers, and there's an external reader or writer for that
+format.
+.SP
+To see if SoX has support for an optional format or device, enter
+.B sox \-h
+and look for its name under the list:
+`AUDIO FILE FORMATS' or `AUDIO DEVICE DRIVERS'.

+\
+Raw (headerless) audio files. For
+.BR raw ,
+the sample rate and the data encoding must be given using command-line
+format options; for the other listed types, the sample rate defaults to
+8kHz (but may be overridden), and the data encoding is defined by the
+given suffix. Thus \fBf32\fR and \fBf64\fR indicate files encoded as 32
+and 64-bit (IEEE single and double precision) floating point PCM
+respectively; \fBs8\fR, \fBs16\fR, \fBs24\fR, and \fBs32\fR indicate 8,
+16, 24, and 32-bit signed integer PCM respectively; \fBu8\fR, \fBu16\fR,
+\fBu24\fR, and \fBu32\fR indicate 8, 16, 24, and 32-bit unsigned integer
+PCM respectively; \fBul\fR indicates `\(*m-law' (8-bit), \fBal\fR
+indicates `A-law' (8-bit), and \fBlu\fR and \fBla\fR are inverse bit
+order `\(*m-law' and inverse bit order `A-law' respectively. For all raw
+formats, the number of channels defaults to 1 (but may be overridden).
+.SP
+Headerless audio files on a SPARC computer are likely to be of format
+\fBul\fR; on a Mac, they're likely to be \fBu8\fR but with a

+AIFF files as used on old Apple Macs, Apple IIc/IIgs and SGI.
+SoX's AIFF support does not include multiple audio chunks,
+or the 8SVX musical instrument description format.
+AIFF files are multimedia archives and
+can have multiple audio and picture chunks\*m
+you may need a separate archiver to work with them.
+With Mac OS X, AIFF has been superseded by CAF.
+.TP
+\&\fB.aiffc\fR, \fB.aifc\fR (also with \fB\-t sndfile\fR)
+AIFF-C is a format based on AIFF that was created to allow
+handling compressed audio. It can also handle little
+endian uncompressed linear data that is often referred to
+as
+.B sowt
+encoding. This encoding has also become the defacto format produced by modern
+Macs as well as iTunes on any platform. AIFF-C files produced
+by other applications typically have the file extension .aif and
+require looking at its header to detect the true format.
+The
+.B sowt
+encoding is the only encoding that SoX can handle with this format.
+.SP
+AIFF-C is defined in DAVIC 1.4 Part 9 Annex B.
+This format is referred from ARIB STD-B24, which is specified for
+Japanese data broadcasting. Any private chunks are not supported.
+.TP
+\fBalsa\fR (optional)
+Advanced Linux Sound Architecture device driver; supports both playing and

+\fBao\fR (optional)
+Xiph.org's Audio Output device driver; works only for playing audio. It
+supports a wide range of devices and sound systems\*msee its documentation
+for the full range. For the most part, SoX's use of libao cannot be
+configured directly; instead, libao configuration files must be used.
+.SP
+The filename specified is used to determine which libao plugin to
+use. Normally, you should specify `default' as the filename. If that
+doesn't give the desired behavior then you can specify the short name
+for a given plugin (such as \fBpulse\fR for pulse audio plugin).
+Examples:
+.EX
+ sox infile \-t ao

+\&\fB.au\fR, \fB.snd\fR (also with \fB\-t sndfile\fR)
+Sun Microsystems AU files.
+There are many types of AU file;
+DEC has invented its own with a different magic number
+and byte order. To write a DEC file, use the
+.B \-L
+option with the output file options.
+.SP
+Some .au files are known to have invalid AU headers; these
+are probably original Sun \(*m-law 8000\ Hz files and
+can be dealt with using the
+.B .ul
+format (see below).
+.SP
+It is possible to override AU file header information
+with the
+.B \-r
+and
+.B \-c
+options, in which case SoX will issue a warning to that effect.
+.TP
+.B .avr

+.TP
+\&\fB.caf\fR (optional)
+Apple's Core Audio File format.
+.TP
+\&\fB.cdda\fR, \fB.cdr\fR
+`Red Book' Compact Disc Digital Audio (raw audio). CDDA has two audio
+channels formatted as 16-bit signed integers (big endian)at a sample
+rate of 44\*d1\ kHz. The number of (stereo) samples in each CDDA
+track is always a multiple of 588.
+.TP
+\fBcoreaudio\fR (optional)
+Mac OSX CoreAudio device driver: supports both playing and recording
+audio. If a filename is not specific or if the name is "default" then
+the default audio device is selected. Any other name will be used
+to select a specific device. The valid names can be seen in the
+System Preferences->Sound menu and then under the Output and Input tabs.

+This format is sometimes used with bit-reversed samples\*mthe
+.B \-X
+format option can be used to set the bit-order.
+.TP
+\&\fB.cvu\fR
+Continuously Variable Slope Delta modulation (unfiltered).
+This is an alternative handler for CVSD that is unfiltered but can
+be used with any bit-rate. E.g.
+.EX

+.EE
+.TP
+.B .dat
+Text Data files.
+These files contain a textual representation of the
+sample data. There is one line at the beginning
+that contains the sample rate, and one line that
+contains the number of channels.
+Subsequent lines contain two or more numeric data intems:
+the time since the beginning of the first sample and the sample value
+for each channel.
+.SP
+Values are normalized so that the maximum and minimum
+are 1 and \-1. This file format can be used to
+create data files for external programs such as
+FFT analysers or graph routines. SoX can also convert
+a file in this format back into one of the other file
+formats.

+.TP
+\&\fB.flac\fR (optional; also with \fB\-t sndfile\fR)
+Xiph.org's Free Lossless Audio CODEC compressed audio.
+FLAC is an open, patent-free CODEC designed for compressing
+music. It is similar to MP3 and Ogg Vorbis, but lossless,
+meaning that audio is compressed in FLAC without any loss in
+quality.
+.SP
+SoX can read native FLAC files (.flac) but not Ogg FLAC files (.ogg).
+[But see
+.B .ogg
+below for information relating to support for Ogg
+Vorbis files.]
+.SP
+SoX can write native FLAC files according to a given or default
+compression level. 8 is the default compression level and gives the
+best (but slowest) compression; 0 gives the least (but fastest)
+compression. The compression level is selected using the
+.B \-C
+option [see
+.BR sox (1)]
+with a whole number from 0 to 8.
+.TP
+.B .fssd
+An alias for the

+.B .gsrt
+Grandstream ring-tone files.
+Whilst this file format can contain A-Law, \(*m-law, GSM, G.722,
+G.723, G.726, G.728, or iLBC encoded audio, SoX supports reading and
+writing only A-Law and \(*m-law. E.g.
+.EX
+ sox music.wav \-t gsrt ring.bin
+ play ring.bin
+.EE
+.TP
+\&\fB.gsm\fR (optional; also with \fB\-t sndfile\fR)
+GSM 06.10 Lossy Speech Compression.
+A lossy format for compressing speech which is used in the
+Global Standard for Mobile telecommunications (GSM). It's good
+for its purpose, shrinking audio data size, but it will introduce
+lots of noise when a given audio signal is encoded and decoded
+multiple times. This format is used by some voice mail applications.
+It is rather CPU intensive.
+.TP
+.B .hcom
+Macintosh HCOM files.
+These are Mac FSSD files with Huffman compression.

+.TP
+\&\fB.ima\fR (also with \fB\-t sndfile\fR)
+A headerless file of IMA ADPCM audio data. IMA ADPCM claims 16-bit precision
+packed into only 4 bits, but in fact sounds no better than
+.BR .vox .
+.TP
+\&\fB.lpc\fR, \fB.lpc10\fR
+LPC-10 is a compression scheme for speech developed in the United
+States. See http://www.arl.wustl.edu/~jaf/lpc/ for details. There is
+no associated file format, so SoX's implementation is headerless.
+.TP
+\&\fB.mat\fR, \fB.mat4\fR, \fB.mat5\fR (optional)

+.B .maud
+An IFF-conforming audio file type, registered by
+MS MacroSystem Computer GmbH, published along
+with the `Toccata' sound-card on the Amiga.
+Allows 8bit linear, 16bit linear, A-Law, \(*m-law
+in mono and stereo.
+.TP
+\&\fB.mp3\fR, \fB.mp2\fR (optional read, optional write)
+MP3 compressed audio; MP3 (MPEG Layer 3) is a part of the patent-encumbered
+MPEG standards for audio and video compression. It is a lossy
+compression format that achieves good compression rates with little
+quality loss.
+.SP
+Because MP3 is patented, SoX cannot be distributed with MP3 support without
+incurring the patent holder's fees. Users who require SoX with MP3 support
+must currently compile and build SoX with the MP3 libraries (LAME & MAD)
+from source code, or, in some cases, obtain pre-built dynamically loadable
+libraries.
+.SP
+When reading MP3 files, up to 28 bits of precision is stored although
+only 16 bits is reported to user. This is to allow default behavior
+of writing 16 bit output files. A user can specify a higher precision
+for the output file to prevent lossing this extra information. MP3
+output files will use up to 24 bits of precision while encoding.
+.SP
+MP3 compression parameters can be selected using SoX's \fB\-C\fR option
+as follows
+(note that the current syntax is subject to change):
+.SP
+The primary parameter to the LAME encoder is the bit rate. If the
+value of the \fB\-C\fR value is a positive integer, it's taken as
+the bitrate in kbps (e.g. if you specify 128, it uses 128 kbps).
+.SP
+The second most important parameter is probably "quality" (really
+performance), which allows balancing encoding speed vs. quality.
+In LAME, 0 specifies highest quality but is very slow, while
+9 selects poor quality, but is fast. (5 is the default and 2 is
+recommended as a good trade-off for high quality encodes.)
+.SP
+Because the \fB\-C\fR value is a float, the fractional part is used
+to select quality. 128.2 selects 128 kbps encoding with a quality
+of 2. There is one problem with this approach. We need 128 to specify
+128 kbps encoding with default quality, so 0 means use default. Instead
+of 0 you have to use .01 (or .99) to specify the highest quality
+(128.01 or 128.99).
+.SP
+LAME uses bitrate to specify a constant bitrate, but higher quality
+can be achieved using Variable Bit Rate (VBR). VBR quality (really
+size) is selected using a number from 0 to 9. Use a value of 0 for high
+quality, larger files, and 9 for smaller files of lower quality. 4 is
+the default.
+.SP
+In order to squeeze the selection of VBR into the the \fB\-C\fR value
+float we use negative numbers to select VRR. -4.2 would select default
+VBR encoding (size) with high quality (speed). One special case is 0,
+which is a valid VBR encoding parameter but not a valid bitrate.
+Compression value of 0 is always treated as a high quality vbr, as a
+result both -0.2 and 0.2 are treated as highest quality VBR (size) and
+high quality (speed).
+.SP

+.TP
+\&\fB.ogg\fR, \fB.vorbis\fR (optional)
+Xiph.org's Ogg Vorbis compressed audio; an open, patent-free CODEC designed
+for music and streaming audio. It is a lossy compression format (similar to
+MP3, VQF & AAC) that achieves good compression rates with a minimum amount
+of quality loss.
+.SP
+SoX can decode all types of Ogg Vorbis files, and can encode at different
+compression levels/qualities given as a number from \-1 (highest
+compression/lowest quality) to 10 (lowest compression, highest quality).
+By default the encoding quality level is 3 (which gives an encoded rate
+of approx. 112kbps), but this can be changed using the
+.B \-C
+option (see above) with a number from \-1 to 10; fractional numbers (e.g.
+3\*d6) are also allowed.
+Decoding is somewhat CPU intensive and encoding is very CPU intensive.
+.SP
+See also
+.B .mp3
+for a similar format.

+.B .prc
+Psion Record. Used in Psion EPOC PDAs (Series 5, Revo and similar) for
+System alarms and recordings made by the built-in Record application.
+When writing, SoX defaults to A-law, which is recommended; if you must
+use ADPCM, then use the \fB\-e ima-adpcm\fR switch. The sound quality is poor
+because Psion Record seems to insist on frames of 800 samples or
+fewer, so that the ADPCM CODEC has to be reset at every 800 frames,
+which causes the sound to glitch every tenth of a second.

+Yamaha TX-16W sampler.
+A file format from a Yamaha sampling keyboard which wrote IBM-PC
+format 3\*d5\(dq floppies. Handles reading of files which do not have
+the sample rate field set to one of the expected by looking at some
+other bytes in the attack/loop length fields, and defaulting to
+33\ kHz if the sample rate is still unknown.
+.TP
+.B .vms
+See
+.BR .dvms .
+.TP
+\&\fB.voc\fR (also with \fB\-t sndfile\fR)
+Sound Blaster VOC files.
+VOC files are multi-part and contain silence parts, looping, and
+different sample rates for different chunks.
+On input, the silence parts are filled out, loops are rejected,
+and sample data with a new sample rate is rejected.
+Silence with a different sample rate is generated appropriately.
+On output, silence is not detected, nor are impossible sample rates.
+SoX supports reading (but not writing) VOC files with multiple
+blocks, and files containing \(*m-law, A-law, and 2/3/4-bit ADPCM samples.
+.TP
+.B .vorbis
+See
+.BR .ogg .
+.TP
+\&\fB.vox\fR (also with \fB\-t sndfile\fR)
+A headerless file of Dialogic/OKI ADPCM audio data commonly comes with the
+extension .vox. This ADPCM data has 12-bit precision packed into only 4-bits.
+.SP
+Note: some early Dialogic hardware does not always reset the ADPCM
+encoder at the start of each vox file. This can result in clipping
+and/or DC offset problems when it comes to decoding the audio. Whilst
+little can be done about the clipping, a DC offset can be removed by
+passing the decoded audio through a high-pass filter, e.g.:
+.EX
+ sox input.vox output.wav highpass 10
+.EE
+.TP
+\&\fB.w64\fR (optional)
+Sonic Foundry's 64-bit RIFF/WAV format.
+.TP
+\&\fB.wav\fR (also with \fB\-t sndfile\fR)
+Microsoft .WAV RIFF files.
+This is the native audio file format of Windows, and widely used for uncompressed audio.
+.SP
+Normally \fB.wav\fR files have all formatting information
+in their headers, and so do not need any format options
+specified for an input file. If any are, they will
+override the file header, and you will be warned to this effect.
+You had better know what you are doing! Output format
+options will cause a format conversion, and the \fB.wav\fR
+will written appropriately.
+.SP
+SoX can read and write linear PCM, floating point, \(*m-law, A-law, MS ADPCM, and IMA (or DVI) ADPCM encoded samples.
+WAV files can also contain audio encoded in many other ways (not currently
+supported with SoX) e.g. MP3; in some cases such a file can still be
+read by SoX by overriding the file type, e.g.
+.EX
+ play \-t mp3 mp3\-encoded.wav
+.EE
+Big endian versions of RIFF files, called RIFX, are also supported.
+To write a RIFX file, use the
+.B \-B
+option with the output file options.
+.TP
+\fBwaveaudio\fR (optional)
+MS-Windows native audio device driver. Examples:
+.EX
+ sox infile \-t waveaudio
+ sox infile \-t waveaudio default
+ sox infile \-t waveaudio 1
+ sox infile \-t waveaudio "High Definition Audio Device ("
+.EE
+If the device name is omitted, \fB-1\fR, or \fBdefault\fR, then you
+get the `Microsoft Wave Mapper' device. Wave Mapper means `use the
+system default audio devices'. You can control what `default' means
+via the OS Control Panel.
+.SP
+If the device name given is some other number, you get that audio
+device by index; so recording with device name \fB0\fR would get the
+first input device (perhaps the microphone), \fB1\fR would get the
+second (perhaps line in), etc. Playback using \fB0\fR will get the
+first output device (usually the only audio device).
+.SP
+If the device name given is something other than a number, SoX tries
+to match it (maximum 31 characters) against the names of the available
+devices.
+.SP

+.BR rec (1),
+and
+.BR sox (1)
+.BR \-d .
+.TP
+.B .wavpcm
+A non-standard, but widely used, variant of
+.BR .wav .
+Some applications cannot read a standard WAV file header for PCM-encoded
+data with sample-size greater than 16-bits or with more than two
+channels, but can read a non-standard
+WAV header. It is likely that such applications will eventually be
+updated to support the standard header, but in the mean time, this SoX
+format can be used to create files with the non-standard header that
+should work with these applications. (Note that SoX will automatically
+detect and read WAV files with the non-standard header.)
+.SP
+The most common use of this file-type is likely to be along the following
+lines:
+.EX
+ sox infile.any \-t wavpcm \-e signed-integer outfile.wav
+.EE
+.TP
+\&\fB.wv\fR (optional)
+WavPack lossless audio compression. Note that, when converting
+.B .wav
+to this format and back again,
+the RIFF header is not necessarily preserved losslessly (though the audio is).
+.TP
+\&\fB.wve\fR (also with \fB\-t sndfile\fR)
+Psion 8-bit A-law. Used on Psion SIBO PDAs (Series 3 and similar).
+This format is deprecated in SoX, but will continue to be used in
+libsndfile.
+.TP
+.B .xa
+Maxis XA files.
+These are 16-bit ADPCM audio files used by Maxis games. Writing .xa files is
+currently not supported, although adding write support should not be very
+difficult.
+.TP
+\&\fB.xi\fR (optional)
+Fasttracker 2 Extended Instrument format.

+NAME
+ SoX - Sound eXchange, the Swiss Army knife of audio manipulation
+
+DESCRIPTION
+ This manual describes SoX supported file formats and audio device
+ types; the SoX manual set starts with sox(1).
+
+ Format types that can SoX can determine by a filename extension are
+ listed with their names preceded by a dot. Format types that are
+ optionally built into SoX are marked `(optional)'.
+
+ Format types that can be handled by an external library via an optional
+ pseudo file type (currently sndfile) are marked e.g. `(also with -t
+ sndfile)'. This might be useful if you have a file that doesn't work
+ with SoX's default format readers and writers, and there's an external
+ reader or writer for that format.
+
+ To see if SoX has support for an optional format or device, enter sox
+ -h and look for its name under the list: `AUDIO FILE FORMATS' or `AUDIO
+ DEVICE DRIVERS'.
+
+ SOX FORMATS & DEVICE DRIVERS
+ .raw (also with -t sndfile), .f32, .f64, .s8, .s16, .s24, .s32,
+ .u8, .u16, .u24, .u32, .ul, .al, .lu, .la
+ Raw (headerless) audio files. For raw, the sample rate and the
+ data encoding must be given using command-line format options;
+ for the other listed types, the sample rate defaults to 8kHz
+ (but may be overridden), and the data encoding is defined by the
+ given suffix. Thus f32 and f64 indicate files encoded as 32 and
+ 64-bit (IEEE single and double precision) floating point PCM
+ respectively; s8, s16, s24, and s32 indicate 8, 16, 24, and
+ 32-bit signed integer PCM respectively; u8, u16, u24, and u32
+ indicate 8, 16, 24, and 32-bit unsigned integer PCM respec‐
+ tively; ul indicates `μ-law' (8-bit), al indicates `A-law'
+ (8-bit), and lu and la are inverse bit order `μ-law' and inverse
+ bit order `A-law' respectively. For all raw formats, the number
+ of channels defaults to 1 (but may be overridden).
+
+ Headerless audio files on a SPARC computer are likely to be of
+ format ul; on a Mac, they're likely to be u8 but with a sample
+ rate of 11025 or 22050 Hz.
+
+ See .ima and .vox for raw ADPCM formats, and .cdda for raw CD
+ digital audio.
+
+ .f4, .f8, .s1, .s2, .s3, .s4,
+ .u1, .u2, .u3, .u4, .sb, .sw, .sl, .ub, .uw
+ Deprecated aliases for f32, f64, s8, s16, s24, s32,
+ u8, u16, u24, u32, s8, s16, s32, u8, and u16 respectively.
+
+ .8svx (also with -t sndfile)
+ Amiga 8SVX musical instrument description format.
+
+ .aiff, .aif (also with -t sndfile)
+ AIFF files as used on old Apple Macs, Apple IIc/IIgs and SGI.
+ SoX's AIFF support does not include multiple audio chunks, or
+ the 8SVX musical instrument description format. AIFF files are
+ multimedia archives and can have multiple audio and picture
+ chunks - you may need a separate archiver to work with them.
+ With Mac OS X, AIFF has been superseded by CAF.
+
+ .aiffc, .aifc (also with -t sndfile)
+ AIFF-C is a format based on AIFF that was created to allow han‐
+ dling compressed audio. It can also handle little endian uncom‐
+ pressed linear data that is often referred to as sowt encoding.
+ This encoding has also become the defacto format produced by
+ modern Macs as well as iTunes on any platform. AIFF-C files
+ produced by other applications typically have the file extension
+ .aif and require looking at its header to detect the true for‐
+ mat. The sowt encoding is the only encoding that SoX can handle
+ with this format.
+
+ AIFF-C is defined in DAVIC 1.4 Part 9 Annex B. This format is
+ referred from ARIB STD-B24, which is specified for Japanese data
+ broadcasting. Any private chunks are not supported.
+
+ alsa (optional)
+ Advanced Linux Sound Architecture device driver; supports both
+ playing and recording audio. ALSA is only used in Linux-based
+ operating systems, though these often support OSS (see below) as
+ well. Examples:
+ sox infile -t alsa
+ sox infile -t alsa default
+ sox infile -t alsa plughw:0,0
+ sox -b 16 -t alsa hw:1 outfile
+ See also play(1), rec(1), and sox(1) -d.
+
+ .amb Ambisonic B-Format: a specialisation of .wav with between 3 and
+ 16 channels of audio for use with an Ambisonic decoder. See
+ http://www.ambisonia.com/Members/mleese/file-format-for-b-format
+ for details. It is up to the user to get the channels together
+ in the right order and at the correct amplitude.
+
+ .amr-nb (optional)
+ Adaptive Multi Rate - Narrow Band speech codec; a lossy format
+ used in 3rd generation mobile telephony and defined in 3GPP TS
+ 26.071 et al.
+
+ AMR-NB audio has a fixed sampling rate of 8 kHz and supports
+ encoding to the following bit-rates (as selected by the -C
+ option): 0 = 4.75 kbit/s, 1 = 5.15 kbit/s, 2 = 5.9 kbit/s, 3 =
+ 6.7 kbit/s, 4 = 7.4 kbit/s 5 = 7.95 kbit/s, 6 = 10.2 kbit/s, 7 =
+ 12.2 kbit/s.
+
+ .amr-wb (optional)
+ Adaptive Multi Rate - Wide Band speech codec; a lossy format
+ used in 3rd generation mobile telephony and defined in 3GPP TS
+ 26.171 et al.
+
+ AMR-WB audio has a fixed sampling rate of 16 kHz and supports
+ encoding to the following bit-rates (as selected by the -C
+ option): 0 = 6.6 kbit/s, 1 = 8.85 kbit/s, 2 = 12.65 kbit/s, 3 =
+ 14.25 kbit/s, 4 = 15.85 kbit/s 5 = 18.25 kbit/s, 6 = 19.85
+ kbit/s, 7 = 23.05 kbit/s, 8 = 23.85 kbit/s.
+
+ ao (optional)
+ Xiph.org's Audio Output device driver; works only for playing
+ audio. It supports a wide range of devices and sound systems -
+ see its documentation for the full range. For the most part,
+ SoX's use of libao cannot be configured directly; instead, libao
+ configuration files must be used.
+
+ The filename specified is used to determine which libao plugin
+ to use. Normally, you should specify `default' as the filename.
+ If that doesn't give the desired behavior then you can specify
+ the short name for a given plugin (such as pulse for pulse audio
+ plugin). Examples:
+ sox infile -t ao
+ sox infile -t ao default
+ sox infile -t ao pulse
+ See also play(1) and sox(1) -d.
+
+ .au, .snd (also with -t sndfile)
+ Sun Microsystems AU files. There are many types of AU file; DEC
+ has invented its own with a different magic number and byte
+ order. To write a DEC file, use the -L option with the output
+ file options.
+
+ Some .au files are known to have invalid AU headers; these are
+ probably original Sun μ-law 8000 Hz files and can be dealt with
+ using the .ul format (see below).
+
+ It is possible to override AU file header information with the
+ -r and -c options, in which case SoX will issue a warning to
+ that effect.
+
+ .avr Audio Visual Research format; used by a number of commercial
+ packages on the Mac.
+
+ .caf (optional)
+ Apple's Core Audio File format.
+
+ .cdda, .cdr
+ `Red Book' Compact Disc Digital Audio (raw audio). CDDA has two
+ audio channels formatted as 16-bit signed integers (big
+ endian)at a sample rate of 44.1 kHz. The number of (stereo)
+ samples in each CDDA track is always a multiple of 588.
+
+ coreaudio (optional)
+ Mac OSX CoreAudio device driver: supports both playing and
+ recording audio. If a filename is not specific or if the name
+ is "default" then the default audio device is selected. Any
+ other name will be used to select a specific device. The valid
+ names can be seen in the System Preferences->Sound menu and then
+ under the Output and Input tabs.
+
+ Examples:
+ sox infile -t coreaudio
+ sox infile -t coreaudio default
+ sox infile -t coreaudio "Internal Speakers"
+ See also play(1), rec(1), and sox(1) -d.
+
+ .cvsd, .cvs
+ Continuously Variable Slope Delta modulation. A headerless for‐
+ mat used to compress speech audio for applications such as voice
+ mail. This format is sometimes used with bit-reversed samples -
+ the -X format option can be used to set the bit-order.
+
+ .cvu Continuously Variable Slope Delta modulation (unfiltered). This
+ is an alternative handler for CVSD that is unfiltered but can be
+ used with any bit-rate. E.g.
+ sox infile outfile.cvu rate 28k
+ play -r 28k outfile.cvu sinc -3.4k
+
+ .dat Text Data files. These files contain a textual representation
+ of the sample data. There is one line at the beginning that
+ contains the sample rate, and one line that contains the number
+ of channels. Subsequent lines contain two or more numeric data
+ intems: the time since the beginning of the first sample and the
+ sample value for each channel.
+
+ Values are normalized so that the maximum and minimum are 1 and
+ -1. This file format can be used to create data files for
+ external programs such as FFT analysers or graph routines. SoX
+ can also convert a file in this format back into one of the
+ other file formats.
+
+ Example containing only 2 stereo samples of silence:
+
+ ; Sample Rate 8012
+ ; Channels 2
+ 0 0 0
+ 0.00012481278 0 0
+
+ .dvms, .vms
+ Used in Germany to compress speech audio for voice mail. A
+ self-describing variant of cvsd.
+
+ .fap (optional)
+ See .paf.
+
+ .flac (optional; also with -t sndfile)
+ Xiph.org's Free Lossless Audio CODEC compressed audio. FLAC is
+ an open, patent-free CODEC designed for compressing music. It
+ is similar to MP3 and Ogg Vorbis, but lossless, meaning that
+ audio is compressed in FLAC without any loss in quality.
+
+ SoX can read native FLAC files (.flac) but not Ogg FLAC files
+ (.ogg). [But see .ogg below for information relating to support
+ for Ogg Vorbis files.]
+
+ SoX can write native FLAC files according to a given or default
+ compression level. 8 is the default compression level and gives
+ the best (but slowest) compression; 0 gives the least (but
+ fastest) compression. The compression level is selected using
+ the -C option [see sox(1)] with a whole number from 0 to 8.
+
+ .fssd An alias for the .u8 format.
+
+ .gsrt Grandstream ring-tone files. Whilst this file format can con‐
+ tain A-Law, μ-law, GSM, G.722, G.723, G.726, G.728, or iLBC
+ encoded audio, SoX supports reading and writing only A-Law and
+ μ-law. E.g.
+ sox music.wav -t gsrt ring.bin
+ play ring.bin
+
+ .gsm (optional; also with -t sndfile)
+ GSM 06.10 Lossy Speech Compression. A lossy format for com‐
+ pressing speech which is used in the Global Standard for Mobile
+ telecommunications (GSM). It's good for its purpose, shrinking
+ audio data size, but it will introduce lots of noise when a
+ given audio signal is encoded and decoded multiple times. This
+ format is used by some voice mail applications. It is rather
+ CPU intensive.
+
+ .hcom Macintosh HCOM files. These are Mac FSSD files with Huffman
+ compression.
+
+ .htk Single channel 16-bit PCM format used by HTK, a toolkit for
+ building Hidden Markov Model speech processing tools.
+
+ .ircam (also with -t sndfile)
+ Another name for .sf.
+
+ .ima (also with -t sndfile)
+ A headerless file of IMA ADPCM audio data. IMA ADPCM claims
+ 16-bit precision packed into only 4 bits, but in fact sounds no
+ better than .vox.
+
+ .lpc, .lpc10
+ LPC-10 is a compression scheme for speech developed in the
+ United States. See http://www.arl.wustl.edu/~jaf/lpc/ for
+ details. There is no associated file format, so SoX's implemen‐
+ tation is headerless.
+
+ .mat, .mat4, .mat5 (optional)
+ Matlab 4.2/5.0 (respectively GNU Octave 2.0/2.1) format (.mat is
+ the same as .mat4).
+
+ .m3u A playlist format; contains a list of audio files. SoX can
+ read, but not write this file format. See [1] for details of
+ this format.
+
+ .maud An IFF-conforming audio file type, registered by MS MacroSystem
+ Computer GmbH, published along with the `Toccata' sound-card on
+ the Amiga. Allows 8bit linear, 16bit linear, A-Law, μ-law in
+ mono and stereo.
+
+ .mp3, .mp2 (optional read, optional write)
+ MP3 compressed audio; MP3 (MPEG Layer 3) is a part of the
+ patent-encumbered MPEG standards for audio and video compres‐
+ sion. It is a lossy compression format that achieves good com‐
+ pression rates with little quality loss.
+
+ Because MP3 is patented, SoX cannot be distributed with MP3 sup‐
+ port without incurring the patent holder's fees. Users who
+ require SoX with MP3 support must currently compile and build
+ SoX with the MP3 libraries (LAME & MAD) from source code, or, in
+ some cases, obtain pre-built dynamically loadable libraries.
+
+ When reading MP3 files, up to 28 bits of precision is stored
+ although only 16 bits is reported to user. This is to allow
+ default behavior of writing 16 bit output files. A user can
+ specify a higher precision for the output file to prevent loss‐
+ ing this extra information. MP3 output files will use up to 24
+ bits of precision while encoding.
+
+ MP3 compression parameters can be selected using SoX's -C option
+ as follows (note that the current syntax is subject to change):
+
+ The primary parameter to the LAME encoder is the bit rate. If
+ the value of the -C value is a positive integer, it's taken as
+ the bitrate in kbps (e.g. if you specify 128, it uses 128 kbps).
+
+ The second most important parameter is probably "quality"
+ (really performance), which allows balancing encoding speed vs.
+ quality. In LAME, 0 specifies highest quality but is very slow,
+ while 9 selects poor quality, but is fast. (5 is the default and
+ 2 is recommended as a good trade-off for high quality encodes.)
+
+ Because the -C value is a float, the fractional part is used to
+ select quality. 128.2 selects 128 kbps encoding with a quality
+ of 2. There is one problem with this approach. We need 128 to
+ specify 128 kbps encoding with default quality, so 0 means use
+ default. Instead of 0 you have to use .01 (or .99) to specify
+ the highest quality (128.01 or 128.99).
+
+ LAME uses bitrate to specify a constant bitrate, but higher
+ quality can be achieved using Variable Bit Rate (VBR). VBR qual‐
+ ity (really size) is selected using a number from 0 to 9. Use a
+ value of 0 for high quality, larger files, and 9 for smaller
+ files of lower quality. 4 is the default.
+
+ In order to squeeze the selection of VBR into the the -C value
+ float we use negative numbers to select VRR. -4.2 would select
+ default VBR encoding (size) with high quality (speed). One spe‐
+ cial case is 0, which is a valid VBR encoding parameter but not
+ a valid bitrate. Compression value of 0 is always treated as a
+ high quality vbr, as a result both -0.2 and 0.2 are treated as
+ highest quality VBR (size) and high quality (speed).
+
+ See also Ogg Vorbis for a similar format.
+
+ .nist (also with -t sndfile)
+ See .sph.
+
+ .ogg, .vorbis (optional)
+ Xiph.org's Ogg Vorbis compressed audio; an open, patent-free
+ CODEC designed for music and streaming audio. It is a lossy
+ compression format (similar to MP3, VQF & AAC) that achieves
+ good compression rates with a minimum amount of quality loss.
+
+ SoX can decode all types of Ogg Vorbis files, and can encode at
+ different compression levels/qualities given as a number from -1
+ (highest compression/lowest quality) to 10 (lowest compression,
+ highest quality). By default the encoding quality level is 3
+ (which gives an encoded rate of approx. 112kbps), but this can
+ be changed using the -C option (see above) with a number from -1
+ to 10; fractional numbers (e.g. 3.6) are also allowed. Decod‐
+ ing is somewhat CPU intensive and encoding is very CPU inten‐
+ sive.
+
+ See also .mp3 for a similar format.
+
+ .opus (optional)
+ Xiph.org's Opus compressed audio; an open, lossy, low-latency
+ codec offering a wide range of compression rates. It uses the
+ Ogg container.
+
+ SoX can only read Opus files, not write them.
+
+ oss (optional)
+ Open Sound System /dev/dsp device driver; supports both playing
+ and recording audio. OSS support is available in Unix-like
+ operating systems, sometimes together with alternative sound
+ systems (such as ALSA). Examples:
+ sox infile -t oss
+ sox infile -t oss /dev/dsp
+ sox -b 16 -t oss /dev/dsp outfile
+ See also play(1), rec(1), and sox(1) -d.
+
+ .paf, .fap (optional)
+ Ensoniq PARIS file format (big and little-endian respectively).
+
+ .pls A playlist format; contains a list of audio files. SoX can
+ read, but not write this file format. See [2] for details of
+ this format.
+
+ Note: SoX support for SHOUTcast PLS relies on wget(1) and is
+ only partially supported: it's necessary to specify the audio
+ type manually, e.g.
+ play -t mp3 "http://a.server/pls?rn=265&file=filename.pls"
+ and SoX does not know about alternative servers - hit Ctrl-C
+ twice in quick succession to quit.
+
+ .prc Psion Record. Used in Psion EPOC PDAs (Series 5, Revo and simi‐
+ lar) for System alarms and recordings made by the built-in
+ Record application. When writing, SoX defaults to A-law, which
+ is recommended; if you must use ADPCM, then use the -e ima-adpcm
+ switch. The sound quality is poor because Psion Record seems to
+ insist on frames of 800 samples or fewer, so that the ADPCM
+ CODEC has to be reset at every 800 frames, which causes the
+ sound to glitch every tenth of a second.
+
+ pulseaudio (optional)
+ PulseAudio driver; supports both playing and recording of audio.
+ PulseAudio is a cross platform networked sound server. If a
+ file name is specified with this driver, it is ignored. Exam‐
+ ples:
+ sox infile -t pulseaudio
+ sox infile -t pulseaudio default
+ See also play(1), rec(1), and sox(1) -d.
+
+ .pvf (optional)
+ Portable Voice Format.
+
+ .sd2 (optional)
+ Sound Designer 2 format.
+
+ .sds (optional)
+ MIDI Sample Dump Standard.
+
+ .sf (also with -t sndfile)
+ IRCAM SDIF (Institut de Recherche et Coordination Acous‐
+ tique/Musique Sound Description Interchange Format). Used by
+ academic music software such as the CSound package, and the
+ MixView sound sample editor.
+
+ .sln Asterisk PBX `signed linear' 8khz, 16-bit signed integer, lit‐
+ tle-endian raw format.
+
+ .sph, .nist (also with -t sndfile)
+ SPHERE (SPeech HEader Resources) is a file format defined by
+ NIST (National Institute of Standards and Technology) and is
+ used with speech audio. SoX can read these files when they con‐
+ tain μ-law and PCM data. It will ignore any header information
+ that says the data is compressed using shorten compression and
+ will treat the data as either μ-law or PCM. This will allow SoX
+ and the command line shorten program to be run together using
+ pipes to encompasses the data and then pass the result to SoX
+ for processing.
+
+ .smp Turtle Beach SampleVision files. SMP files are for use with the
+ PC-DOS package SampleVision by Turtle Beach Softworks. This
+ package is for communication to several MIDI samplers. All sam‐
+ ple rates are supported by the package, although not all are
+ supported by the samplers themselves. Currently loop points are
+ ignored.
+
+ .snd See .au, .sndr and .sndt.
+
+ sndfile (optional)
+ This is a pseudo-type that forces libsndfile to be used. For
+ writing files, the actual file type is then taken from the out‐
+ put file name; for reading them, it is deduced from the file.
+
+ sndio (optional)
+ OpenBSD audio device driver; supports both playing and recording
+ audio.
+ sox infile -t sndio
+ See also play(1), rec(1), and sox(1) -d.
+
+ .sndr Sounder files. An MS-DOS/Windows format from the early '90s.
+ Sounder files usually have the extension `.SND'.
+
+ .sndt SoundTool files. An MS-DOS/Windows format from the early '90s.
+ SoundTool files usually have the extension `.SND'.
+
+ .sou An alias for the .u8 raw format.
+
+ .sox SoX's native uncompressed PCM format, intended for storing (or
+ piping) audio at intermediate processing points (i.e. between
+ SoX invocations). It has much in common with the popular WAV,
+ AIFF, and AU uncompressed PCM formats, but has the following
+ specific characteristics: the PCM samples are always stored as
+ 32 bit signed integers, the samples are stored (by default) as
+ `native endian', and the number of samples in the file is
+ recorded as a 64-bit integer. Comments are also supported.
+
+ See `Special Filenames' in sox(1) for examples of using the .sox
+ format with `pipes'.
+
+ sunau (optional)
+ Sun /dev/audio device driver; supports both playing and record‐
+ ing audio. For example:
+ sox infile -t sunau /dev/audio
+ or
+ sox infile -t sunau -e mu-law -c 1 /dev/audio
+ for older sun equipment.
+
+ See also play(1), rec(1), and sox(1) -d.
+
+ .txw Yamaha TX-16W sampler. A file format from a Yamaha sampling
+ keyboard which wrote IBM-PC format 3.5" floppies. Handles read‐
+ ing of files which do not have the sample rate field set to one
+ of the expected by looking at some other bytes in the
+ attack/loop length fields, and defaulting to 33 kHz if the sam‐
+ ple rate is still unknown.
+
+ .vms See .dvms.
+
+ .voc (also with -t sndfile)
+ Sound Blaster VOC files. VOC files are multi-part and contain
+ silence parts, looping, and different sample rates for different
+ chunks. On input, the silence parts are filled out, loops are
+ rejected, and sample data with a new sample rate is rejected.
+ Silence with a different sample rate is generated appropriately.
+ On output, silence is not detected, nor are impossible sample
+ rates. SoX supports reading (but not writing) VOC files with
+ multiple blocks, and files containing μ-law, A-law, and
+ 2/3/4-bit ADPCM samples.
+
+ .vorbis
+ See .ogg.
+
+ .vox (also with -t sndfile)
+ A headerless file of Dialogic/OKI ADPCM audio data commonly
+ comes with the extension .vox. This ADPCM data has 12-bit pre‐
+ cision packed into only 4-bits.
+
+ Note: some early Dialogic hardware does not always reset the
+ ADPCM encoder at the start of each vox file. This can result in
+ clipping and/or DC offset problems when it comes to decoding the
+ audio. Whilst little can be done about the clipping, a DC off‐
+ set can be removed by passing the decoded audio through a high-
+ pass filter, e.g.:
+ sox input.vox output.wav highpass 10
+
+ .w64 (optional)
+ Sonic Foundry's 64-bit RIFF/WAV format.
+
+ .wav (also with -t sndfile)
+ Microsoft .WAV RIFF files. This is the native audio file format
+ of Windows, and widely used for uncompressed audio.
+
+ Normally .wav files have all formatting information in their
+ headers, and so do not need any format options specified for an
+ input file. If any are, they will override the file header, and
+ you will be warned to this effect. You had better know what you
+ are doing! Output format options will cause a format conversion,
+ and the .wav will written appropriately.
+
+ SoX can read and write linear PCM, floating point, μ-law, A-law,
+ MS ADPCM, and IMA (or DVI) ADPCM encoded samples. WAV files can
+ also contain audio encoded in many other ways (not currently
+ supported with SoX) e.g. MP3; in some cases such a file can
+ still be read by SoX by overriding the file type, e.g.
+ play -t mp3 mp3-encoded.wav
+ Big endian versions of RIFF files, called RIFX, are also sup‐
+ ported. To write a RIFX file, use the -B option with the output
+ file options.
+
+ waveaudio (optional)
+ MS-Windows native audio device driver. Examples:
+ sox infile -t waveaudio
+ sox infile -t waveaudio default
+ sox infile -t waveaudio 1
+ sox infile -t waveaudio "High Definition Audio Device ("
+ If the device name is omitted, -1, or default, then you get the
+ `Microsoft Wave Mapper' device. Wave Mapper means `use the sys‐
+ tem default audio devices'. You can control what `default'
+ means via the OS Control Panel.
+
+ If the device name given is some other number, you get that
+ audio device by index; so recording with device name 0 would get
+ the first input device (perhaps the microphone), 1 would get the
+ second (perhaps line in), etc. Playback using 0 will get the
+ first output device (usually the only audio device).
+
+ If the device name given is something other than a number, SoX
+ tries to match it (maximum 31 characters) against the names of
+ the available devices.
+
+ See also play(1), rec(1), and sox(1) -d.
+
+ .wavpcm
+ A non-standard, but widely used, variant of .wav. Some applica‐
+ tions cannot read a standard WAV file header for PCM-encoded
+ data with sample-size greater than 16-bits or with more than two
+ channels, but can read a non-standard WAV header. It is likely
+ that such applications will eventually be updated to support the
+ standard header, but in the mean time, this SoX format can be
+ used to create files with the non-standard header that should
+ work with these applications. (Note that SoX will automatically
+ detect and read WAV files with the non-standard header.)
+
+ The most common use of this file-type is likely to be along the
+ following lines:
+ sox infile.any -t wavpcm -e signed-integer outfile.wav
+
+ .wv (optional)
+ WavPack lossless audio compression. Note that, when converting
+ .wav to this format and back again, the RIFF header is not nec‐
+ essarily preserved losslessly (though the audio is).
+
+ .wve (also with -t sndfile)
+ Psion 8-bit A-law. Used on Psion SIBO PDAs (Series 3 and simi‐
+ lar). This format is deprecated in SoX, but will continue to be
+ used in libsndfile.
+
+ .xa Maxis XA files. These are 16-bit ADPCM audio files used by
+ Maxis games. Writing .xa files is currently not supported,
+ although adding write support should not be very difficult.
+
+ .xi (optional)
+ Fasttracker 2 Extended Instrument format.

+
+/* Overview:
+
+ There is a large number of synthesis packages in use or development
+ on the Linux platform at this time. This API (`The Linux Audio
+ Developer's Simple Plugin API') attempts to give programmers the
+ ability to write simple `plugin' audio processors in C/C++ and link
+ them dynamically (`plug') into a range of these packages (`hosts').
+ It should be possible for any host and any plugin to communicate
+ completely through this interface.
+
+ This API is deliberately short and simple. To achieve compatibility
+ with a range of promising Linux sound synthesis packages it
+ attempts to find the `greatest common divisor' in their logical
+ behaviour. Having said this, certain limiting decisions are
+ implicit, notably the use of a fixed type (LADSPA_Data) for all
+ data transfer and absence of a parameterised `initialisation'
+ phase. See below for the LADSPA_Data typedef.
+
+ Plugins are expected to distinguish between control and audio

+ * freely redistributable and may be used for any purpose. This copyright
+ * notice must be maintained. Chris Bagwell And Nick Bailey are not

+ *
+ *
+ * Usage:
+ * mcompand quoted_compand_args [crossover_frequency
+ * quoted_compand_args [...]]
+ *
+ * quoted_compand_args are as for the compand effect:
+ *
+ * attack1,decay1[,attack2,decay2...]
+ * in-dB1,out-dB1[,in-dB2,out-dB2...]
+ * [ gain [ initial-volume [ delay ] ] ]
+ *
+ * Beware a variety of headroom (clipping) bugaboos.
+ *
+ * Implementation details:
+ * The input is divided into bands using 4th order Linkwitz-Riley IIRs.
+ * This is akin to the crossover of a loudspeaker, and results in flat
+ * frequency response absent compander action.
+ *
+ * The outputs of the array of companders is summed, and sample truncation
+ * is done on the final sum.
+ *
+ * Modifications to the predictive compression code properly maintain
+ * alignment of the outputs of the array of companders when the companders
+ * have different prediction intervals (volume application delays). Note
+ * that the predictive mode of the limiter needs some TLC - in fact, a
+ * rewrite - since what's really useful is to assure that a waveform won't
+ * be clipped, by slewing the volume in advance so that the peak is at
+ * limit (or below, if there's a higher subsequent peak visible in the

+ * the bitrate in kbps (that is if you specify 128, it use 128 kbps).
+ *
+ * The second most important parameter is probably "quality" (really
+ * performance), which allows balancing encoding speed vs. quality.
+ * In LAME, 0 specifies highest quality but is very slow, while
+ * 9 selects poor quality, but is fast. (5 is the default and 2 is
+ * recommended as a good trade-off for high quality encodes.)
+ *
+ * Because encoding.compression is a float, the fractional part is used
+ * to select quality. 128.2 selects 128 kbps encoding with a quality
+ * of 2. There is one problem with this approach. We need 128 to specify
+ * 128 kbps encoding with default quality, so .0 means use default. Instead
+ * of .0 you have to use .01 to specify the highest quality (128.01).
+ *
+ * LAME uses bitrate to specify a constant bitrate, but higher quality
+ * can be achieved using Variable Bit Rate (VBR). VBR quality (really
+ * size) is selected using a number from 0 to 9. Use a value of 0 for high
+ * quality, larger files, and 9 for smaller files of lower quality. 4 is
+ * the default.
+ *
+ * In order to squeeze the selection of VBR into the encoding.compression
+ * float we use negative numbers to select VRR. -4.2 would select default
+ * VBR encoding (size) with high quality (speed). One special case is 0,
+ * which is a valid VBR encoding parameter but not a valid bitrate.
+ * Compression value of 0 is always treated as a high quality vbr, as a
+ * result both -0.2 and 0.2 are treated as highest quality VBR (size) and
+ * high quality (speed).
+ *
+ * Note: It would have been nice to simply use low values, 0-9, to trigger
+ * VBR mode, but 8 kbps is a valid bit rate, so negative values were

+ *
+ * February 22, 1996
+ * by Chris Bagwell (cbagwell@sprynet.com)
+ * Added support for block type 8 (extended) which allows for 8-bit stereo
+ * files. Added support for saving stereo files and 16-bit files.
+ * Added VOC format info from audio format FAQ so I don't have to keep
+ * looking around for it.
+ *
+ * February 5, 2001
+ * For sox-12-17 by Annonymous (see notes ANN)
+ * Added comments and notes for each procedure.
+ * Fixed so this now works with pipes, input does not have to
+ * be seekable anymore (in startread() )
+ * Added support for uLAW and aLaw (aLaw not tested).
+ * Fixed support of multi-part VOC files, and files with
+ * block 9 but no audio in the block....
+ * The following need to be tested: 16-bit, 2 channel, and aLaw.

+
+ (Source is fax from Barry Boone at Creative Labs, 405/742-6622)
+
+BLOCK 8 - digitized sound attribute extension, must preceed block 1.
+ Used to define stereo, 8 bit audio
+ BYTE bBlockID; // = 8
+ BYTE nBlockLen[3]; // 3 byte length
+ WORD wTimeConstant; // time constant = same as block 1
+ BYTE bPackMethod; // same as in block 1
+ BYTE bVoiceMode; // 0-mono, 1-stereo
+
+ Data is stored left, right
+
+BLOCK 9 - data block that supersedes blocks 1 and 8.
+ Used for stereo, 16 bit (and uLaw, aLaw).
+
+ BYTE bBlockID; // = 9
+ BYTE nBlockLen[3]; // length 12 plus length of sound
+ DWORD dwSamplesPerSec; // samples per second, not time const.
+ BYTE bBitsPerSample; // e.g., 8 or 16
+ BYTE bChannels; // 1 for mono, 2 for stereo
+ WORD wFormat; // see below
+ BYTE reserved[4]; // pad to make block w/o data
+ // have a size of 16 bytes
+
+ Valid values of wFormat are:
+
+ 0x0000 8-bit unsigned PCM
+ 0x0001 Creative 8-bit to 4-bit ADPCM
+ 0x0002 Creative 8-bit to 3-bit ADPCM
+ 0x0003 Creative 8-bit to 2-bit ADPCM
+ 0x0004 16-bit signed PCM
+ 0x0006 CCITT a-Law
+ 0x0007 CCITT u-Law
+ 0x02000 Creative 16-bit to 4-bit ADPCM
+
+ Data is stored left, right
+
+ ANN: Multi-byte quantities are in Intel byte order (Little Endian).
