Post by twobuc24waorth »

I saw this person use adafruit products to make a voice changer https://www.youtube.com/watch?v=ivkczjoOXHc

gives a pretty full sound compared to the basic arduino vioce changers on youtube.
but i also found this voice changer project using a different product.

To get effects like echo/reverb, you need memory to store a collection of previous samples.

Our voice changer doesn't do that. It captures one millisecond worth of samples then plays them back at a different rate. That difference in sampling/playback speeds shifts the frequency of the sound up or down. It doesn't store enough information to do reverb though.

Take a look at the Teensy Audio Library:

The Teensy microcontrollers have plenty of RAM and processing power for audio processing, and you can build audio filter signal paths using a visual interface.
