anyone here ever built a vocoder?

is there a kit or schematic you recommend?

>anyone here ever built a vocoder?

no, no anywhere has ever done that.

Tried a few years ago, never got it to work right, probably because I cheaped out on components and was following a pretty janky schematic. Would not recommend unless you have plenty of experience with analog systems, have a good understanding on the theory and high quality components.

No but I'd like to. They seem kind of overpriced for the low complexity of the circuit, but I guess they're sort of a niche sound so maybe it's a supply and demand thing

They are simple in theory, getting one to sound good or even work is some form of black magic.

>They are simple in theory

anything you don't understand must be easy.

yes, but just a cheap digital one

>>2602898 (OP)

how do these things even work? is it all digital, or is there a way of doing it analog?

traditionally vocoders are completely analog but modern systems tend to do it in software

the challenge with doing it analog is you need to make the circuit at least 10 times (they tend to have at least 10 frequency channels)

to minimise cost I'd suggest using simple Sallen-Key (resistor/capacitor) filters and to bulk purchase the opamps, you should be able to use TL072 everywhere.

Also make it one band block at the time. May sound obvious but for it's important to have something useable (one way or another) at every step of the way.
