Some dejitter circuits would "fix" (mask) the slight pitch error as well.
They have memories and buffer up the music and clock it out at hopefully a more accurate clock (the DAC clock). The problem with this is, that if the buffer overflows it has to toss data. Or if it underflows it has to wait. This can be a slight crack or pop. If the buffer isn't too big it won't get too far ahead or behind to notice. So it's trade off. On my Meridian system I can turn this FIFO on or off. The option is called "Poor Digital Sources" (i.e. ones with bad drift). If it's off it just locks on to the clock of the SPDIF. If on it uses the internal clock and the FIFO. It actually has 3 levels of FIFO's I think to help smooth buffer underrun and overrun issues. I don't know all the details. With the SqueezeBox 3 I can leave the FIFO on (i.e. SqueezeBox 3 is considered a "good" digital source). Poor Jitter will also give the FIFO fits. -- mswlogo ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=35866 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
