Moreover, as you certainly know, any abrupt start and stop of sound produces distortion (which is the "sic" way of stating that the sampling theory can't reproduce the sound). Because the theory says "Any sudden beginning or ending amounts to high frequency content. A sine burst itself contains a sine wave and a gating wave (turning the sine on and off). The gate requires infinite bandwidth. A different way to state this is that the sinc functions at the beginning and end are truncated.". So, is there something that I forgot ? -- Themis SB3 - North Star dac 192 - Denon 3808 - Sonus Faber Grand Piano Domus ------------------------------------------------------------------------ Themis's Profile: http://forums.slimdevices.com/member.php?userid=14700 View this thread: http://forums.slimdevices.com/showthread.php?t=53355 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
