Go for the ssb example (H09) it uses the hilbert transform to do a complex modulation. It's a frequency shifter (not a pitch shifter) but it works for this kind of modulation.
You may also use some other pitch shifter as well for that. Cheers _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
