I'm looking to create a portable stereo audio device.  This system is
exactly what I am looking for:

http://www.amis.com/products/dsp/belasigna_200.html

However the evaluation and development tools are thousands of dollars
which puts it out of reach.  Can someone put me on the right path to a
similar solution where there are gcc tools available?  Thank you.

You should look how to get the thousands of dollars first. If you are 
not worth thousand of dollars, you obviously not capable of developing a 
portable audio device.

Don't be discouraged by some folks' negative remarks.

If you first need to learn how to work with DSPs, then where you lack 
financial resources you will have to compensate with intelligence, 
careful research, and prudence.  You will still need at least several 
hundred dollars to buy a typical evaluation kit, possibly nearing and 
exceeding $1000 to get some additional support items if needed like some 
cheap electronic test equipment (check into the use of PC sound cards 
though for spectrum analysis, etc.)

Start researching the DSP product offerings, evaluation kits, tools, 3rd 
party tools, and developer communities surrounding TI and Analog Devices 
DSPs.  Get onto comp.arch.dsp .  Also, look at Danville Signal and other 
vendors, who might have something to get you started in the sub-$1000 
range.  Carefully research what is available, and which product both 
will suit your intended application AND has available free or low cost 
tools that will allow you to bypass the need to purchase the 
manufacturer's full-blown development tools.  This might force you to 
have to write assembly language at worst (although for ADI DSPs, might 
be rather easy-going), or to use gcc/gdb which isn't so bad (but still 
more painful than I can tolerate, but I can afford at least a few 
$1000s, even for hobby purposes.)

My DSP interest is in servo control, laser shows, and other fast 
real-time control stuff, so the TI TMS320F2812 and similar DSPs/tools 
have afforded me the ability to play with >100MIPS for well less than $1000.

This is different from actually producing a "portable audio product" in 
which case you need to create something manufacturable and cost 
effective.  Then you will indeed need many $1000s.

Also consider if you can do what you want with something simpler than a 
DSP, like a cheaper ARM SBC, for ex.

Have fun.

TI's DSP kits start at $99 but Joel wants to built something portable. 
Many regular DSP eat batteries as if they were popcorn.

What I'm doing doesn't have to be all that complex.  It'll be on the order
of complexity of a voice changer.  Is there a better digital option than
DSP?

I'm a student so the freer the better.

If you just want mono speech a dsPIC and Si3000 codec should do what
you want. dsPIC development software is free.

You can probably do what you want with an AVR32 (uC3B)
