[sdiy] Digital synthesis using statistical functions?

[Ben Lincoln]

I didn't seem to get a huge amount of interest about this, but in case 
any of you were waiting for lengthier discussion of this topic, a more 
flexible utility to experiment with (including the ability to specify 
the pitches of the component sine waves in hertz), more example 
parameter sets to use as a starting point, or a wider variety of sample 
mp3s, all of those things are now present :).

I think I've taken the command-line version about as far as I have an 
interest in doing, so this will probably be my last update to it for the 
foreseeable future. At some point, I'd like to write a StudioFactory or 
maybe VST plugin that will allow the same thing to be done in realtime 
(assuming no one else does so before me), but that's a long way off at best.
