Ya, but before you hear it, it enters the analogue world and frequency response is limited. All of the hard sharp corners get modified. This happens even digitally before the DAC as far as I know. Even analogue there are many kinds of clipping, and to add to the mess there is limiting as well... another kind of distortion that sounds less distortion like :) One of the first distortion units I made was just two diodes shorting off the peaks. It sounded very different from even a transistor amp pushed too hard. Tube amps are different again. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
