Fons, I want just polinomial transformation regardless harmonics at all. I have mentioned harmonics as a result of searching a LADSPA plugin related to my needings. I'm afraid direct amplitude caculation in accorance with a0...aN will produce "too fast" signal deviation, resulting in exceeding fs/2 band.
