BTW, question for anybody who can help.
The compansion function is basically a bounded,
single-quadrant version of
f(x) = (1 - exp(x)) / (1 - exp(alpha))
mirrored into a second quadrant for x < 0, for compansion
factor alpha.
This kind of waveshaping is usually analyzed in terms of
harmonic content. It would be great to be able to express
the compansion in dB, but I don't have the first clue how to
derive it, beyond integrating and scaling, and that doesn't
yield anything intelligible so far. Any ideas?
For what it's worth, the compander is nothing more than a
tame fuzz box :-)
