• I’ve been wanting to follow this tutorial for some time. I think this might make the whole thing way simpler and smaller if all I want is line in.

  • I recently bought a Behringer U-phono UFO202 as a cheap DAC for my mini pc. Can this Pi thing replace it?
  • 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).

    • Did you ever use Dirac Live and can compare the results? Hardware that supports Dirac is unfortunately very expensive.
  • Looks like output only and only one stereo pair from USB is processed to outputs, but a really cool project.

  • Nice.

    I wonder if 264/520 kB RAM is also enough for a high quality parametric stereo reverb/echo effect? Should fit about 3/6 seconds of uncompressed 16-bit 44.1/48 kHz audio.

    Also: Raspberry Pi Ltd - please keep increasing the RAM size in future iterations to unlock even more use cases!
