Use BeagleBone Black to make cool guitar effects #beagleboneblack @TXInstruments @beagleboardorg

YouTube user Giulio Moro made this cool video demonstrating his cool guitar effects made using BeagleBone Black.

A quick demo of the wah wah effect I programmed on a Beaglebone Black as an assignment for the Real Time DSP module taught by Andrew McPherson at Queen Mary University Of London.
Two buttons, a potentiometer.
Features:

  • filter cutoff can be controlled by external pedal or by signal envelope
  • two switchable filter cutoff range, “hi” for guitar and “lo” for bass
  • built in overdrive which gain is controlled by the potentiometer
  • the overdrive can be moved before or after the filter
  • controls can be assigned to the acceleromter (not shown in this demo)
