As it sounds like you would be building the hardware, I would suggest you l=
ook at one of Microchips DSP starter kits, probably a single simple PCB usi=
ng a PIC33 series chip, rather than the explorer 16 with appropriate PIM. M=
icrochip do have a library of DSP functions for doing auto-level control, e=
cho cancel, etc. and I would suggest having a dig around in there for suita=
ble code modules.

I haven't used any of their DSP stuff, so don't know how good it is, but fo=
r minimal $ it should give you a starting point.
