Sometimes redlining is a good thing.
Warning - Please tweak responsibly at low volume levels.
Mr Krinkle - control squelch via marked In1
For the mods marked "Turn In1" raise it slowly and watch upper osc.
Dunno if that qualifies as wavefolding but it looks cool.
Edit: answer is NO!
"Wavefolding is a type of distortion synthesis where when the input amplitude exceeds the threshold, the peaks get cut off, similar to digital clipping. The difference is that in wavefolding, the curved amplitude peaks get inverted into a series of folds.
These folds produce complex spectra from simple waveforms so when you run a single sine wave through a wavefolder, very strange harmonics will emerge. Interestingly, saw and pulse waves may remain generally unaffected by wavefolding, but a mathematical explanation of this behavior is beyond the scope of this article.
Most wavefolders include an additional variable, sometimes called offset, that adds a positive or negative voltage bias. This offset shifts the center point of the input signal up or down. A positive offset will cause the positive sections of the signal to have higher amplitude while the negative sections will have less amplitude. Because of this, the user is able to apply more distortion to the positive signal than the negative signal, making this a non-linear distortion. In fact, with certain settings, you can even apply wavefolding to just the positive sections of the signal while leaving the negative sections unmodified or vice-versa."
