We built NORMLZ — a fully client-side audio normalizer that runs entirely in your browser. No uploads, no accounts, no cloud nonsense. Your files never leave your machine.
What makes it different from the usual “just slap a limiter on it” tools:
- Three normalization modes — True Peak, RMS, and integrated LUFS
- Whole-mix loudness — your stereo image and channel balance stay completely intact
- High-quality resampling — export at 44.1 / 48 / 96 kHz with no artifacts
- Brickwall limiter with configurable ceiling and automatic intersample headroom compensation
- Multiple export formats — 16, 24, 32-bit PCM and 32-bit float WAV
- Batch processing with one-click folder export (no save dialogs on Chrome/Edge)
We’d love feedback from anyone who works with audio seriously.
