I read this tutorial - it's quite interesting and extremely well written. The bottom line though is that this technique differs from the standard DAC technique only in that the bandwidth of the PLL is smaller. In the thread he says it's around 3 Hz, which is pretty small for audio frequency stuff, but I wonder what the comparable number is for a standard S/PDIF PLL. Knowing that would allow one to compare the jitter rejecting capabilities of ASRC to a standard DAC. So this technique does not completely eliminate jitter. Contrast that to the Lavry technique, or any true buffering-and-reclocking technique, which totally eliminates it. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=29450 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
