Incoming bad question.

I'm trying to make a voice changer that I can use to flip through different pitches/tones. I don't need it to be feature rich or have tons of buttons. Even a single knob would be enough. Just something to hook up to the tiny speaker hidden on my shoulder and the tiny mic that fits in my mask. The concept itself is pretty darn simple, so it boggles my mind that NOBODY on the internet has done it, to my knowledge.

All the results I've found are either [A] people with devices that do one specific voice (e.g. darth vader) but never ones that you can shift around, or [B] ones you can shift around, but they're online voice changers for the computer to use at home on programs like skype or discord. Clearly neither of those options work. Phone apps are also obviously out of the question. It needs to be an analog input so I don't have to babysit a touch screen. I should be able to change the dial/switches/whatever without looking, and not be stuck wondering "why isn't it changing, did I hit the home button, did it just turn off, am I touching the wrong spot on the screen, did i accidentally click on some mandatory update that takes ten hours, aahhhhh".

Anyhow, I'm not begging for a step-by-step walkthrough or anything, I'm just trying to figure out if it's even possible, because I have found jack on the subject and folks like y'all are generally much smarter than I am with this stuff, and I'd rather not resort to strapping a guitar peddle to my face.
Alright. Thanks for reading.
