I made a (non-scientific, but sounds ok to my (bad) ears...) resonant 
low-pass filter, see attached.  two zeros at 1/2 sampling rate, plus two 
poles (conjugate pair) that can be moved about controlled by audio 
input.  The gain formula comes from Miller's book, iirc, and I probably 
misused it, but it seems to work ok.
