AudioDSP crunchy distortion effect based on the pedalSHIELD.
Crunch.ino is a crunchy distortion effect from the pedalSHIELD examples. The pushbuttons control the volume of the output signal.
- distortion is derived from an asymmetrical clipping system based on Schetzen formula
Not so great. The asymmetrical algorithm results in a fat bottom end but some annoying high-frequency distortion.
See SuperCrunch for the symmetrical version, which is much more pleasing.
This example uses a private AudioDspDriver library that contains my refactoring of the core algorithms for driving the board. I may split this out as a stand-alone library at some point.
