Then what is your question ? All you need to do is compute

Or even better: evaluate the Chebyshev polynomials directly on
the signal (this avoids loss of precision due to cancellation of
large nea

This can be done with waveshaping.
If your source is a sinewave you can run it's

..or, saying about my aim, is there softwa
How does Steve Harris' Harmonic generator LADSPA plugin work? I mean relation
between controls (concrete harmonics levels) and transfer function
Vout = Vin(1 + a*Vin + b*Vin^2 + ...)
