[sdiy] software wavefolding

The best links I know are:

http://www.rs-met.com/documents/tutorials/Waveshaping.pdf

I've experimented a little bit with this in the digital domain. Most of the examples that you see are with sine wave inputs and with chebyshev polynomials for the waveshaping function. This makes the analysis easy, but produces boring results with one sinewave going in and several sinewaves coming out - since the sinewaves are all fixed harmonics (e.g. no beating) it mostly sounds like a cheap electric organ, which gets tedious pretty fast.
My recommendation is to put rich, dynamic signals in, and use weird-looking complex shapes to bend them. The analysis will be a total bitch (if you care) but you might find something exciting, and at least you'll have no idea what you'll get 'til you try it! ;)

HTH,
Tom
