Here's an interesting waveshaping distortion that is not linear and gives an interesting effect. I once ported it to pd but I did not quite finish it (I didn't get the coefficient calculations right and it would blow up in some unpredictible ways). http://csounds.com/ezine/winter1999/processing/ A gentler (than abs(),[abs~] or similar) way of rectifying a signal is multiplying it by itself. ./MiS _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
