codebook 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 2005-10-31 18:56:29 +00:00

COPYING 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 2005-10-31 18:56:29 +00:00
decoder.c 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
