The previous defaults caused audible volume fluctuations ("pumping")
especially at low-to-moderate listening levels:
- 30ms analysis window reacted to individual transients instead of
sustained loudness, causing rapid gain swings on drum hits
- 15 dB max boost created dramatic level changes between quiet and
loud passages
- 5000ms gain release made recovery audibly slow, creating a
"breathing" effect as gain slowly crept back up
- -48 dB noise floor allowed aggressive boosting of near-silence
Tuned defaults:
- analysisWindowMs: 30 → 100 (smooths transients, measures phrases)
- maxBoostDb: 15 → 6 (meaningful lift without dramatic pumping)
- gainAttackMs: 180 → 250 (smoother gain reduction)
- gainReleaseMs: 5000 → 3000 (faster recovery, less "swell")
- detectorReleaseMs: 400 → 600 (holds peaks longer, reduces jitter)
- noiseFloorThresholdDb: -48 → -40 (protects quiet material)
- lowLevelMaxBoostDb: 1.5 → 0.5 (conservative at very low levels)

Heads-up: This PR and fix was generated by Claude, but I did manually review it and test it! No sloppy unsupervised AI code here :)
