Yes, Audacity is pretty good. There is no way you will ever get anything beyond +-1 shown on the waveform display, because it represents 0 dBFS (or full scale). A digital signal can never go beyond that. The analog output from the DAC van go beyond 0dB FS as a result of the interpolating filter filling in the "missing" clipped peak. What the Audacity clipping detector does is detect places where the full scale was not enough to represent the wave, and the signal got clipped as a result. ------------------------------------------------------------------------ Julf's Profile: http://forums.slimdevices.com/member.php?userid=42050 View this thread: http://forums.slimdevices.com/showthread.php?t=98180 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
