Wavefolding

Wavefolding is a special case of waveshaping, working with periodic transfer functions. Depending on the pre-gain, the source signal gets folded back, one a maximum of the transfer function is reached. Compared to the previously introduced soft clipping or other methods of waveshaping, this adds many strong harmonics.
