Arduino realtime audio processing

<br />



This is an experiment to show how some realtime audio processing can be done with the Arduino. The first set of examples alter an incoming audio signal and put it back to an audio output. We achieve effects like Reverb, Phasor, Flanger or Ringmodulator. The second set of examples are outputting computed waveforms like Sinewave, Bell and Xylophone sounds.

This is on my list of things to do. I’ve been working more and more with electronics lately. It’s something that I learned from my father when I was a kid, and I feel closer to him working on circuits. Before he died I remember calling him and asking a question about potentiometers, and talking about the PCB I had just made.
