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.
