OK - if you buy an EZ-KIT from ADI then they'll throw in a code-size 
limited version of VisualDSP+ with it. Looks like the EZ-Kit on the page 
you linked will run you about $400. That's not too far out of the price 
range of the Tiny Board system you called out earlier, assuming you buy 
all the goodies required for audio.

If you buy a system from Tiny Board though I suppose you'd either have 
to shell out for the full version, or try to do all your development in 
3 months. :)

Microchip does have a fairly complete library of DSP functions that are 
accessible from the C programming environment.

Those requirements put you squarely into the high-end DSP market. Forget 
everything I said about the dsPIC - it's too underpowered for your 
application.

Not at all. But it'll cost ya. :)
