This is what I hope to emulate with interpolated Hermite spline
coefficients: as the signal levels increase, the transfer curves change.

I finished up my "Interpolated Hermite Waveshaper Coefficient Designer" app
this weekend. I currently have a Windows version compiled; if I get any help
to compile it for Mac and Linux (it hopefully will cross-compile, GUI and
all, with no hitch) I'll offer up those flavours as well. I'll also offer
the sourcecode to the app to anyone interested. Be warned, it was a learning
experience in wxWindows, so it's uglier code than usual...and that's going a
ways ;)

I need to write a short readme.txt user manual (should get that done
tonight)...then where should I put it? Is the archive a good place for
something this large and esoteric (Windows exe alone is 500K statically
linked), or should I post on my own webspace (which I'll hafta whip up...no
