i am interested in vocoders but haven't had much luck penetrating the math involved with any patch or documentation about them. and it seems that the term 'vocoder' is applicable in a broader range of contexts than i thought. when i think of a 'vocoder,' i think of some device that allows you to filter one sound source according to the frequency analysis of another, thus you could, for example, produce an effect not unlike a guitar talk box by filtering audio of your voice according to the spectral analysis of a guitar playing. are there any patches set up for this type of task? where one could load two sound files and 'map' them on to each other?

i want a vocoder for pd toooo!
the voice effect is a vocoder

try this one. it's the rjdj e_vocoder. it's nice!

i made a vocoder the other day. hopefully have included all the bits and pieces in this .zip file

alistair_blunt: I tried your file and I like it. Thanks to that, I discovered RjDj libraries, they are great! I didn't know that they were free to use.

I realized that you change a little the patch, using 3 phasor~ instead of 4. Why?
Did you try another values to get different effects? Could you share with us?

Mod: I downloaded vocoder-test.zip. It looks great, but there's no diytanh.pd, that is inside vocovoice.pd. So... it doesn't work. I'm very insterested in your patch.

Can a vocoder have the same pitch of the voice? Maybe using fiddle~ to feed the oscilator...
