Release 1.2-alpha
This is an alpha release with many improvements, including:
- Speech quality improvements especially in the 12-20 kbit/s range
- Improved VBR encoding for hybrid mode
- More aggressive use of wider speech bandwidth, including fullband speech
starting at 14 kbit/s
- Music quality improvements in the 32-48 kb/s range
- Generic and SSE CELT optimizations
- Support for directly encoding packets up to 120 ms
- DTX support for CELT mode
- SILK CBR improvements
- Support for all of the fixes in draft-ietf-codec-opus-update-04 (the mono
downmix and the folding fixes need --enable-update-draft)
- Many bug fixes, including integer overflows discovered through fuzzing
(no security implications)
Improves CELT bit allocation at very low bitrates
We now try not to fold below band 17 since that produces a lot of harshness.
This mostly helps around 32-40 kb/s.
