I did compare wav but I probably made a mistake: I can confirm that the output is bitexact with the Windows app and your patch. > For me flac it is not identical but wav is. > (probably due to different flac encoders?) I also used the FFmpeg flac encoder when producing the sample file... Not all of the comments on top of the filter file look very useful to me, what do you think? In any case, I'd say a link to these should be useful: http://www.audiomisc.co.uk/HFN/HDCD/Enigma.html http://www.audiomisc.co.uk/HFN/HDCD/Examined.html (Or only the second one.) Please also add a fate test, since this is using floats, I would suggest to only compare pcm_s16 (instead of 24).
