The new samples are inserted and given zero-values. The result is then low-pass filtered. Remember, we have a special case of a bandlimited signal. Sampling theory means we can recover this signal - in all its complex, musical glory, no matter how unintuitive and surprising this first seems. ------------------------------------------------------------------------ flimflam's Profile: http://forums.slimdevices.com/member.php?userid=56891 View this thread: http://forums.slimdevices.com/showthread.php?t=99088 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
