I've been working on a system in Max to make procedurally-generated sounds for creatures in a game. I came across a video on YouTube that uses pfft~ to analyze speech samples and apply the frequency analysis to a basic waveform in order to create "speech-like" sounds. I have set up the following (see attached patcher). While this produces OK results, I am looking for ways to create distinct and varied sounds. I have been experimenting quite a bit with it already, but haven't been successful finding techniques that produce good results. For example, I've tried pitch-modulating my carrier signal in all sorts of ways, putting different bands through overdrive~, putting the pfftout~ signal through a modulating lores~, without much luck.

I am looking for ways to further enhance this system. I'm not looking for an easy way out here, but just for tips to point me in the right direction. I couldn't attach the sounds that I'm using since they're from BOOM and the license belongs to my school. Recording your own voice into it should be sufficient I think.

Any help and/or insights are much appreciated!!

Hi all,

(gotta share your "vocoder_main" patch too, to load pfft~ properly)

vocoder_main.maxpat

here's some simple options attached, i won't spend any time explaining these(sorry, it's a very deep subject and i'm not even an expert, plus if i were i'd probably charge quite a bit for that knowledge), but one thing i can say real quick is that i prefer to play with the value coming out of cartopol~'s right-inlet, because those are 'phase' values, while the ones coming out of the left-inlet are 'magnitude'(similar to amplitude).....(and additionally, you could research 'instantaneous frequency' and use framedelta~, phasewrap~, and frameaccum~ objects to play with that in different ways).

if you're still confused, this stuff takes alot to learn so i can only advise to read carefully through all these tutorials:

https://cycling74.com/tutorials/the-phase-vocoder-%E2%80%93-part-i

https://cycling74.com/tutorials/the-phase-vocoder-part-ii

plus the regular reference/tutorial stuff about FFT.

alternately, you're welcome to just take the pfft~ easter egg i dropped in the patch here(it's a type of morph worked with complex math rather than using cartopol~/poltocar~), but i made it confusing in appearance so nobody would learn my secrets 😜, so if you use that, just rearrange the outer pfft~ container patch, don't worry about what's inside the actual pfft~ and that way you'll know where the inputs go:

Thanks so much for the elaborate help, fantastic stuff. I'll post my results on here when I get somewhere.
