[sdiy] Wave Shaping?

[Grant Richter]

The Blacet/Wiard Mini-Wave is the most advanced waveshaper ever offered
commercially.

Non-linear synthesis begins with a sine wave of unit amplitude (1).
Tchebychev polynomials are used to convert the sine wave into any arbitrary
harmonic content. Mike Firman has some C code that takes a set of harmonic
amplitudes and converts them into the function needed to distort a sine wave
into having those harmonic amplitudes.

Hey, Mike why don't you tell us about it?
