PAF synthesis ask me some question.
lets take the example F12.paf.pd
since the modulator (the waveshaper at the right which generate the formant) range from 0 to 1 (unipolar), dont we have to speak about Amplitude Modulation, and not Ring Modulation ?
in Curtis Roads "Computer Music Tuto" we see that the Amplitude Mod (AM) is made with a unipolar modulator, whereas Ring Modulation (RM) need a bipolar one. And also that with the AM the partials from the carrier are present, whereas in RM thoses partials are removed so that we get only sidebands.
With the PAF, we see that the partials from the carrier are also present in the resulting signal... then why its name ring mod ?
