Hey everyone...

I'm trying to do a soft saturation distortion module using the fexpr~ object.. but for some reason i'm getting a syntax error when I enter the following:

fexpr~ (($x1/(pow((abs(pow$x1, 2))+1))), 0.5)

Any ideas? Thanks!

Hello everyone!

So... I've decided to embark on my second major project in Pd... a Harmonizer. basically, I want to create a phase vocoder for live usage, that is, I want to be able to sing into Pd and have my voice come out an octave/3rd/5th/etc higher/lower.

From what I understand, I'll need to use a FFT, but I have no real idea where to start with this. I'm in the process of watching the stanford web series "The Fourier Transform and its Applications"... but I don't really have time to sit through ~30 hours of videos to get one application done.

I've looked through the forum (nothing) and the help file in Pd goes clear over my head. Is there anyone out there willing to help? I know that I'd need to find the frequency, shift the frequency by x + 2^(1/12).. then resynthesize without changing the period. Right?

GAH! help please!

Thanks,
AJ

Gah! That's it!

And I could've sworn that I had done that exact same thing a billion times.... sometimes you just need a fresh pair of eyes

thanks!

Hmm.. nope... still giving me an error!

Ralf-

I will certainly check it out! I would, however, like to learn the fft theory behind the harmonizer so I can do it my self, if only out of principal (and because it looks far more impressive). Are there any readings you could recommend?
