1334738071 Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall.

3fa5e5f592 Apply a bunch of simple AAC decoder optimizations. Biggest speedup is on ColdFire targets, but ARM targets benefits too. Allows realtime playback of some AAC files on Iriver targets (H1x0, H3x0). Remove support for some rarely used AAC profiles to reduce code size a bit.

65de1cc6af Initial check-in of unmodified libfaad (part of the FAAD2 project). This is the last version of libfaad available under the GPL - the state of FAAD2 CVS at midnight on 2005-02-01
