Apparently there is another mechanism besides the one you mention here by which jitter can be correlated to the music, and that is what I've been trying (and evidently totally failing!) to describe. It's that the isynchronous digital voltage signal itself contains some frequency components which are related to the spectrum of the original analogue signal that was digitized. Given that some jitter is "correlated", meaning the timing errors you mentioned are not random but instead are influenced by the digital signal itself, this means some of the jitter spectrum will be correlated to the original music (and some won't). -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=24670 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
