Tangentially related, I recently had some hand-me-down high-end full tower speakers lose their integrated subwoofer 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 loudspeaker corrected fancy DSP and the speakers sound better than ever. Pretty fun, and very cheap. The Pi3 runs it using about 20% of its CPU. Not bad! 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 real-time rather than CamillaDSP).
Ah that’s super cool. Wish I knew about this a week earlier. Just last week I got the iLoud sub to correct speakers for my living room because I wanted a standalone piece of equipment that’s not my PC that can hold the corrected EQ/phase.
Why not use a crossover driver?
The loudspeaker would have used one; a driver is both cheaper and of higher quality.
Did you ever use Dirac Live and can compare the results? Hardware that supports Dirac is unfortunately very expensive.
