Nice script :) I did a similar thing by hand with graphicsmagick and sox a couple years ago - the most fun result was from wahwah, pretty much a wide bandpass filter with centre frequency varying cyclically over time: http://lewisinthelandofmachines.tumblr.com/post/59405537096/...

I haven't even tried the wahwah effect, you've definitely piqued my interest.
I had a look through the SoX effects list[1] for the wahwah, but can't seem to find it. The closest thing I found was the 'flanger' effect[2].
