CamillaFIR vs Conventional EQ-Based Room Correction (v3.5.5)

Conventional approach (typical IIR / minimum-phase EQ)

Many room-correction workflows:

  • treat response errors mainly as magnitude EQ problems
  • focus on PEQ/IIR fitting with limited phase-domain control
  • do not directly control decay behavior
  • can overfit reflection-driven dips and combing

Common consequences

  • bass can get flatter but still ring
  • narrow treble corrections can sound harsh
  • results may change noticeably with small mic-position differences

CamillaFIR approach (current)

Aspect Conventional EQ CamillaFIR
Input sources usually frequency-response only REW TXT + WAV/IR inputs
Propagation delay (TOF) often implicit explicitly removed before phase analysis
Phase strategy mostly minimum-phase behavior Linear / Minimum / Mixed / Asymmetric + optional 2058-safe mode
Excess-phase safety limited Mixed-phase fade + excess-delay and pre-ringing guards
Room modes / ringing mainly amplitude shaping Temporal Decay Control (TDC) with strength + max reduction + slope limit
Reflection handling may invert combing dips confidence-weighted correction + smoothing + A-FDW
Correction bounds tool-dependent explicit limits for boost/cut/slope/phase band and low-bass safety
Headroom handling manual gain staging auto-headroom gain model with configurable margin
Stereo consistency often per-channel behavior stereo-link options and shared gain behavior
Reproducible A/B harder across fs/taps optional comparison mode with fixed analysis grid
Multi-rate output uncommon native multi-rate FIR export
Runtime diagnostics often limited Summary version stamp, timing breakdown, and System Health checks

Audible result (typical)

  • tighter bass decay (less overhang)
  • fewer “false-detail” treble corrections
  • cleaner transients with safer phase behavior
  • more repeatable tuning between runs

CamillaFIR intentionally avoids aggressive inversion and prioritizes corrections that remain stable and physically plausible.
