Hmm.. OK, in that sense. However, there is no jitter introduced when doing a mathematical upsampling. The jitter portion happens on an SPDIF transmitter/cable/receiver line. Asynchrounous clocks sounds like a stupid idea. IMHO any reasonable upsampling should be done in exact multiples of the original sample rate. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=26685 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
