Tangentially related, I recently had some hand-me-down high-end full tower speakers lose their integrated subwooer amps. I bypassed them and wired in an external amp but people said the integrated DSP would be missing. That's when I learned about CamillaDSP [1] and CamillaFIR [2]. I got a calibrated UMIK-1 microphone and did a frequency sweep in the room. Then I applied the camilla-computed FIR filter to my snapcast-sourced music stream on the Raspberry Pi 3 B I have networked into the living room. Now I have room-corrected and loundspeaker corrected fancy DSP and the speakers sound better than ever. Pretty fun, and very cheap. I did the same process up in my office with some desk speakers and they sound great too (that time using EasyEffects to apply the filter in realtime rather than CamillaDSP).
> I can't take all of the credit. My little robot intern (Opus 4.5) has been very helpful with the busy work, leaving me free to handle the trickier planning and implementation. ;)
I wonder if 264kB RAM is also (barely) enough for a high quality stereo reverb/echo effect? Should fit about 3 seconds of uncompressed 16-bit 44.1/48 kHz audio.
Also: Raspberry Pi Ltd - please add a little more RAM in future iterations to unlock more use cases.

Looks like output only and only one stereo pair from USB is processed to outputs, but a really cool project.

Is there a guaranteed latency?

Nice.
