Arduino Vocal Effects Box

Andrea RealiSeptember 21st, 2012

Have you ever wished to build a box to distort and pitch your voice? Here we go.

Amanda Ghassaei has published an inspiring Instructable to guide you in building an Arduino Vocal Effects Box.

It samples an incoming microphone signal at a rate of about 40kHz, manipulates the audio digitally, and then outputs 8 bit audio at a rate of about 40kHz. Here you can hear a sample of the sounds that can be obtained.

I highly recommend to follow Amanda’s website because it seems that she is working on other experiments with digital signal processing using Arduino.
