 Manipulating Vocals Using Arduino
Amanda Ghassaei made a vocal effects box that digitizes the human voice using the granular synthesis function on Arduino. Audio comes in at 40khz, is digitized, then outputted in 8 bit sound.

Melodies sung are distinct in both tone and timbre, as evidenced by the Somewhere Over the Grainbow sample track. But the granular synthesis introduces it’s own distinct tonal characteristics to change the sound as it’s being digitized. The result could easily be blended into your favorite electronic tracks.

Amanda posted an Instructable on the project, including steps on how to create the handsome triangular enclosure she made.
