I would handle this as a chain of FIR filters with decimation to get much lower tap count FIR filters that don't need to be nearly as steep in the early stages. Maybe using Blackman-Harris windowed filters for the first two stages (for superior alias fold-in rejection). Then a Kaiser windowed filter for the 3 stage to get a flatter top and a sharper roll-off....

Without re-hashing all of the maths from RBJs response, I made a crummy little plug in that did more/less what you are proposing. It had a stupid simple GUI with one slide for nominal amplitude and several more to control harmonic levels. It was OK, but not as useful as one would hope for audio work. The idea was that given a sinusoid with a nominal input ...

The answer is "sorta". Lot's of assumptions, though. This is related to that other question where you've been. This is about waveshaping of a single sinusoid (without harmonics) by performing a polynomial operation on a sinusoid having an amplitude of 1 and any frequency. It is memoryless, which will mean that the waveshaping operation is (at ...
