Revert part of r7561, "Refactor audio conversion functions."

Specifically, revert this part:

  "Remove hacks in AudioBuffer intended to maintain bit-exactness with
   the float path. The conversions etc. are now all natural, and
   instead we enforce close but not bit-exact output between the two
   paths."

But keep the conversion function rename, since that doesn't seem to be
causing problems.
