As I understand it, that rounding is the cause of jitter. A (basic) DAC uses rising or falling edges as a clock, but since as you say those edges aren't very well defined that introduces errors. If the DAC used its own clock, since that will not be exactly in sync with the transport's clock it will either fall behind or get ahead, causing errors eventually as it starts to read the wrong bit. Same problem with a buffer, unless it's really really big I guess... -- 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 audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
