* Commit fix by Tom Ross in FS#7488 wherein a silly mistake noise coding ↵Michael Giacomelli2008-12-20

* Combine the Vorbis, WMA and AAC IMDCT functions and put them into the ↵Michael Giacomelli2008-09-04
| | | | | | codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18412 a1c6a512-1295-4272-9138-f99709370657

| | | | | | 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18084 a1c6a512-1295-4272-9138-f99709370657

* Put the WMA windowing and output buffer into IRAM on targets with > 96KB of ↵Michael Giacomelli2008-06-28

* Revert r14786 which resulted in a substantial reduction in accuracy to save ↵Michael Giacomelli2008-06-24
