common.h Further libfaad cleanup. Make libfaad compilable for floating point. Floating point cannot be used as reference though, as errorous noise is the result. 2010-09-14 06:03:39 +00:00

filtbank.h Fix FS#10174 by correcting an oversimplification of the AAC window switching code I introduced with the unified IMDCT library. Should significantly improve accuracy for all AAC files. 2009-04-29 17:44:02 +00:00

huffman.c Submit FS#11445. Speed up of faad (aac) decoder via several optimizations like refactoring some requantization routines, moving several arrays and code tables to IRAM, using an optimized swap32() function and inlining several huffman decoder functions. Decoding is sped up by ~10% (PP5002, PP5022, MCF5249) and ~22% (MCF5250). 2010-07-01 21:18:42 +00:00

sbr_dct.c Minor correction to macros, beautification of loop. 2010-07-11 18:41:41 +00:00
sbr_dct.h Submit FS#11461. Major speedup for aac he profile (PP5002 +20%, PP5020 +15%, PP5022 +19%, MCF5249 +35%, MCF5250 +80%), still not realtime on most targets though. This change does a lot of refactoring in the sbr filters and the dct, switching to our optimized codeclib fft and tweaking IRAM usage. 2010-07-09 18:32:37 +00:00

sbr_fbt.h
sbr_hfadj.c Fix scaling error that was introduced with r28069. With this fix the level of the hf-spectrum will be correct when decoding aac-he files. 2010-09-14 19:31:00 +00:00

specrec.c Fix libfaad error that was introduced with r27225. Noise bursts during playback of several files were reported in the forums. 2010-08-23 23:14:32 +00:00
specrec.h
structs.h 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
syntax.c Disable AAC-SBR, AAC-SSR, and AAC-PS on Sansa clip. Clean up warnings introduced by this. Enable compiling the AAC codec on the Clip. Due to lack of memory for seek tables, files over 10 minutes long or so will probably fail. 2009-04-25 03:51:58 +00:00
