Hi, This patch adds dithered outputs for both ogg and mp3lib (pentium mode) plugins. The patch works for me, but a lot of work can be done: -better declaration of dithertable -add code for other codecs/CPU/modes. (even for replaygain on lossless files) -make dither optional using configure or commandline -..... For more background, details, (audible!) test results... see: http://213.84.144.87/dither123 The patch is split into 3 parts: 1) libvorbis patch. 2) mp3lib patch (pentium assembler routines changed + ugly hack to force pentium mode for x86 CPUs) Note: The web page mentioned shows the mmx-routine is broken as sound quality is concerned! 3) a large table.(for space saving reasons this patch isn't attached but it can be DLed from the site mentioned.) It looks like this: diff -Naur ./MPlayer-20050516/dither.h ./MPlayer-20050516dither/dither.h --- ./MPlayer-20050516/dither.h 1970-01-01 01:00:00.000000000 +0100 +++ ./MPlayer-20050516dither/dither.h 2005-04-21 04:21:13.000000000 +0200 @@ -0,0 +1,65541 @@ +/* table holding dither values. noise shaping used */ + + + +float dithertable[65536]={ +-0.126371, +0.497872, +-0.779434, +0.843073, +-0.646505, Regards from Adrian Bacon
