Wave Folding

Pioneered by Don Buchla (west coast synthesis) , Wave Folding is a form of wave shaping that literally folds the edges of a wave inwards on itself until the wave starts compressing creating distortion.

Wave Folding is a unique way to create complex sounds with strange harmonics from simple waveforms.


Additional variables, sometimes called offset, add a positive or negative voltage bias and shift the center point of the input signal up or down to create a form of non-linear distortion.
