Really impressive! Does this board allow F.I.R. filtering?

I don't think it's a matter of the board, it's probably more of a question about ADAU170 at Engineer Zone:

FIR and general filtering on ADAU1701. Hints ab... | EngineerZone

Thanks for the link. The journey begins I think.

I'm looking for something that I can use that has both quality and versatility.

The idea of working with passive loudspeaker filters is pretty much a non starter over here. All my design work in the past six years has been active only.

There is a similar board described in Article #6 at Audiodevelopers.com. The picture shows an early prototype--got new boards on their way. The article isn't complete, but I'll document the build for the new boards and post the results. Article 12 describes the software.

Is the board called AWDSP?
Can it be considered as a "next generation" freeDSP?
Can we buy a board - either fully populated, or just the SMDs done, or ..?

"Next generation" is a bit exaggerated. It's a freedsp with audio widget on board and additional dac. I can sell some with smd ICs or fully populated, PM me.
