It’s no news that we’re Arduino nuts here at Gearfuse, but lately, we haven’t seen anything that has really pushed the boundaries of the popular microcontroller. Now some smarty pants named Martin has come along with a schematic that allows real-time audio processing with the Arduino. This means you can create guitar FX pedals, equalizers and a whole lot of digital instruments thanks to this setup. Says Martin:
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.
Think you can handle it, Mr. Programmer? Then get to it.
