One thing to note when doing this kind of math: for lossless formats (whether FLAC or WMA doesn't matter), as you go from 16 bits to 24 bits, you can expect your compression ratio to go down substantially. That is to say, you will get almost no compression to speak of on the next 8 bits, because they are mostly noise. This is not intended as a commentary on the practicality of 24-bit sampling, only to say that this is what a lossless encoder will "see". I have not really investigated this myself, but it's what I would expect. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=40315 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
