The sofa beams Audio DPS boards...there are several models...are stand alone boards, no coach needed. Simply insert in your audio chain and add power. It works great. Far better than I had hoped. They are worth the investment.

That looks like a cool implementation. Is your audio bandpass filter stand alone or is it an add-on to the Sotabeams filter board?

It sounds like it is a stand alone DSP filter and display.

Is the code on GitHub or somewhere?
