You can't encode a clean squarewave in 44.1 KHz format - it's impossible. You either have Gibbs ringing or a more rounded waveform. In that trace it looks like you have both. Basically, the problem is the corners. To make a sharp corner one needs infinite frequency (since the derivative of the signal changes infinitely fast). -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=53345 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
