How does a voice pedal change the sound of your voice going through a microphone?
My friend, Sue, has a voice pedal that has hundreds of voices you can use to spice the songs you sing. Her brother used it once to do 'Alvin and chipmunks' just to have a little fun. While I was sitting there listening to her I was trying to figure out how that works. Her brother doesn't have a high pitch voice, it's actually pretty deep. It's not like he put a cloth over the microphone to muffle the sound or use a different voice.

I'm not sure how it works either. Instead of a normal voice changer though, I use certain guitar pedals. I do this by having a non-powered lapel mic connected to an in-line power source [in other words a battery configuration to make it compatible with the pedal], and the pedal's output is connected to two daisy chained X-Mini II speakers. [This only works with some pedals.]

If the frequency changes the pitch is altered. If the amplitude is changed, volume is altered (sound pressure). Since frequency is inversely proportional to wavelength, a higher pitched sound will have a shorter wavelength. Raising the frequency or shortening the wavelength then, will give the Chimpmunk sound.

If you could record and playback a very short loop at different speeds at the same time, with speed differences of 6% per change of note, you would have a live analog pitch changer that is musically correct. It is easier to build but harder to program the same digital effect, which is not much different than autotune, I think.
