Most notably Miller Smith Puckette, whose doctoral thesis was a
Probability Theory paper titled:

    "Shannon Entropy and the Central Limit Theorem"

http://www-crca.ucsd.edu/~msp/Publications/thesis.ps



And about waveshaping, let me say that, for "big distortion", in addition
to the tanh(x) and atan(x)*2/pi functions that I may have previously
mentioned, x/sqrt(1+x*x) and erf(x) are quite cool. They aren't
particularly modeling the behaviour of analog amps nor speaker membranes,
but still, they're rather simple functions that appear everywhere in
science.
