This is a code example that demonstrates basic principles of audio digital signal processing and sound synthesis in MaxMSP. Specifically it shows how waveshaping works.
The last synthesis method uses a waveshaping technique to generate the new sound spectrum. With a Chebyshev polynomial a non-linear function is used to modulate the carrier oscillator. The transfer function that is created distorts the original signal in unlimited different ways. You may have a look at this tutorial in Waveshaping, and check the following code written in MaxMSP.
