[SqueakAudio] Generating "Soothing Sounds"

[Mark Guzdial]

I was wondering something this weekend, and thought that maybe this 
list might have the folk who can point me toward my answer -- though 
the question is not exactly the main focus of this list.

During a particularly child-noisy point this weekend, I got to 
thinking about those "pleasant sound" generating gadgets that I see 
in the stores these days: The ones that generate the sound of falling 
rain, or whatever.

- How do these work?  Are they just playing samples over and over 
(perhaps in different orders)?  Or are they actually synthesizing the 
sounds?

- If the latter, does anyone have any sample code that can do this 
kind of synthesis?  My preference is for Squeak code, please, but 
understandable pseudo-code, MATLAB/MATHEMATICA, or even C code would 
be interesting.

Thanks!
  Mark
