I am new to PD, just started taking a Sound Synth class on it and I am struggling. For a project, i want to make a basic vocoder patch. What I want is to be able to speak or sing into a mic and control my voice using a simple oscillator, controlled by a midi keyboard. So far this is what I have but it doesn't work. If anyone could tell me what I am missing it would be awesome, help is much appreciated.

Thanks

Hi and welcome to this forum,

I would recommend you to have a look on the material created by Alexandre Porres that is available in our main site: look for the link named Computer Music with Examples in Pd version from jan 2012 at https://puredata.info/docs/tutorials. This is a package containing several amazing pure data patches discussing digital audio in general, and he has a whole section only about vocoders there.

Take care,
Gilberto

@nw6829a here's a complete implementation of Miller's vocoder:

you need to install mtl abstractions:
