My original thoughts were to take something like Brute-Fir and adapt
it with a pulseaudio IO module. Since you can already prod BruteFir
with a CLI it seemed like a good way to get something going that could
have a GUI grafted onto it afterwards.
Did you look at this approach and reject it for some reason?
