Hello all.
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 ?

thx.

hmm maybe its because Puckette dont use the difference RM and AM ? I dont find AM example in Puckette theory & techniques of electronic music ...

maybe Puckette see the AM as a special case of RM, where the modulator have a DC offset.

Yes surely and in his book he explains why he uses only the positive part of a sine (the bell-curve must be the equivalent).
Maybe you can also have a look at his paper Formant based audio synthesis using nonlinear
distortion

thx for answering.

yes its done. it does not really help me since it deals more with math (complex number) explanation
