Michael Giacomelli 1620d1fd03 Correct poor assumption on my part that WMA frames are 2048 samples long. Fixed problems with sample rates < 44.1khz. Fixes FS#9242 and FS#9439. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18805 a1c6a512-1295-4272-9138-f99709370657		2008-10-14 01:41:26 +00:00

SOURCES	Combine the Vorbis, WMA and AAC IMDCT functions and put them into the 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.	2008-09-04 18:02:10 +00:00

wmafixed.h	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.	2008-07-17 17:43:49 +00:00
