Software for Cubic Nonlinear Distortion

The function cubicnl in the Faust software distribution (file effect.lib) implements cubic nonlinearity distortion [454]. The Faust programming example cubic_distortion.dsp provides a real-time demo with adjustable parameters, including an offset for bringing in even harmonics. The free, open-source guitarix application (for Linux platforms) uses this type of distortion effect along with many other guitar effects.

In the Synthesis Tool Kit (STK) [91], the class Cubicnl.cpp implements a general cubic distortion law.
