Hi, i'm trying to build a simple analog voice distortion circuit, without any ICs if it's possible. It can get pretty hard to hunt down a specific IC around here. Anyhow, my idea was to get a mic, a speaker, a few oscillators, analog multipliers and RLC filters to build a real time distortion (it will be a portable device, so it will be DC powered). I know it's probably too much to ask, but the original idea was that the distortion came out as kinda robotic, but it's not a must, any cool distortion will do it. Can anyone point me in the right direction? I'm sort of the electrical engineering student with a lot of theoretical knowledge and little experience, so spare no explanations. Maybe just tell me a good waveform to multiply the input with and i'll search how to do it.. any help is appreciated. Pretty much everything I found involved an IC, so if I there's any chance I could avoid that, that'd be great. Thanks!
