* Initial support for ATRAC3 streams in wav containers. Mohamed Tarek2010-02-16
| | | | | | | | | | | | | | Current state : - Playback and seeking are possible. - We now support ATRAC3 in any of its possible containers (wav/at3, oma/aa3, and rm/ra). TODO : - Fix joint-stereo decoding for ATRAC3 - the decoder currently produces lots of glitches. - Rename atrac3_oma.c since it works for both oma and wav containers. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24689 a1c6a512-1295-4272-9138-f99709370657
