Was playing some background music using the livingroom setup, and felt that it was quite bright, and had that "boxy" sound. Decided to turn my attention to tweaking the livingroom setup.

Moode PEQ settings.

Post EQ sweep.

Brightness fixed. Boxy overtones still there (EQ cannot fix). Sounds more balanced...

After further listening ... confirm it is tonally more balanced ...

Only 2 things left, that EQ cannot fix ...
  • boxy overtones - my guess is from the speaker cabinet resonances
  • slightly echo-ey presentation - my guess is from the minimally furnished living + dining area.

I think I can use this setup to learn more about CamillaDSP ... and play with advanced FIR filters to replace the PEQ filters.

My first attempt was totally messed up and generated this very loud noise, thankfully it didn't blow my speakers. I made the mistake of configuring the FIR filter file as FLOAT32LE, instead of WAVE. Finally got it working!!

Documenting my journey here.

1. Use REW to generate the correction EQ (per normal).

2. Export the FIR filter as impulse response WAV file. I choose mono, 32bit float, 44k1.

3. Enable MPD resampling of all material to a base rate that matches the impulse filter (I choose 44k1).

4. Configure CamillaDSP and load up the impulse filter (make sure to choose WAV filetype). I put in -2dB gain for safety.

5. May the room corrected music begin!!
