Steve, Cost? I know you can get commercial audio DSPs like the Shure unit for approx. $1000.

You don't need a full featured DSP. What you need is DAP.
Every major vendor such as AD, TI, NXP, Cirrus, AKM, ST, etc. offers DAPs and evaluation boards for them. The cost is going to be few hundred dollars. Check this, for example:
Vladimir Vassilevsky DSP and Mixed Signal Design Consultant
I'm dating myself. Yes, I need a DAP!
Thank you Dr. Vassilevsky.....

Do you really need fancy software or just a board that will do some filtering which can be tuned a bit? I recently designed a very simple signal processing board for a customer to do some dedicated filtering and tone detection which can be produced for quite competitive prices; the digital version is cheaper than the analogue version and needs no post-production adjustments.
