Re: Voice Project help
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.
