Solving the problem with a buffer is not straightforward. The read and write clocks will never be at exactly the same frequency (and won't be constant either), but they are at the same nominal frequency. The problem is akin to having a bucket half-full of water, with a tap filling it from the top, and then trying to adjust a tap at the bottom such that the bucket neither overflows or runs dry. In a practical sense you will never be able to achieve it without regular intervention. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=50147 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
