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.

e76f30a57c Improvements to specialized dividers for APE codec: 
* Use Newton-Raphson divider on ARMv5e and ARMv6, about 7% speedup on Gigabeat S.
* On ARMv4 targets using IRAM, remove insane filter buffer from IRAM, fill available IRAM with LUT of reciprocals for small divisors - speedup varies according to target and available IRAM, APE normal sample is approx. 109% RT on e200.
* Rename apps/codecs/lib/udiv32_armv4.S to apps/codecs/lib/udiv32_arm.S, which includes dividers for all ARM targets specialized for APE.
