CamillaFIR - FIR Filter Maker & Room Correction Filter Generator

CamillaFIR is an automatic FIR filter maker / generator that turns REW measurements into convolution FIR filters you can load into:

• CamillaDSP
• Roon (Convolution)
• Equalizer APO (and similar convolution engines)

CamillaFIR is listed in the official CamillaDSP README under Measurement and filter generation tools, as a recommended tool for measurement-based filter generation.

What CamillaFIR does

• Converts measurement data (for example REW exports) into FIR correction filters
• Produces convolution-ready output files (WAV FIR + companion config files)
• Helps you avoid common pitfalls like excessive boost and unstable corrections
• Includes tools/plots to inspect results (magnitude, phase, IR)

Typical workflow

1. Measure your speakers / room with REW (load your microphone calibration file first)
2. Export measurements (for TXT include magnitude + phase; for WAV use Mono, float32, Normalise, Place t=0 (256))
3. Generate correction filters with CamillaFIR
4. Load the resulting FIR WAV into CamillaDSP / Roon / Equalizer APO
5. Verify the result (measurement + listening)
