3a9852be1c I don't yet fully understand why this is required, but without it the output is signed-inverted (compared to e.g. the output of oggdec). ac3 confirmed to be ok so the problem must be in the imdct not the ifft. but the algo seems correct (in that seems same as original ffmpeg version)..

82f05895af Initial support for ATRAC3 streams in wav containers. 
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.
