Yes, I agree. DC should properly be defined as the zero frequency component of the Fourier transform - which is the same thing as the time average of the waveform - and is clearly zero for this example. About the asymmetry, is there a good way to quantify what we mean by that? It seems that the characteristic of my artificial sound which made the polarity audible was its asymmetry, but I don't immediately see how to make that precise... maybe the higher odd moments, meaning the average of the third or fifth power or whatever of the waveform? If there were such a measure, one could apply it to music or sound waves and see which are likely to be audibly different after a polarity reversal. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=23759 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
