Audacity's "Sliding Time Scale/Pitch Shift" can do something like it, but 
it doesn't seem to go to low enough pitch to sound right.  Also, on my 
laptop this effect crashes on short selections, so I had to slow down the 
piece of audio I was playing with to make it long enough, then do the 
effect and speed it up again.

It looks like it could be done using the "Nyquist prompt" in Audacity - 
this would require learning something about Nyquist scripting, which is a 
sort of lisp for sound processing.  I looked at the docs for a minute and 
it looks like Nyquist's "sound-warp" function is a good starting point.
