Volume Normalizer

Measures the peak and RMS loudness of an audio file and rescales it to a target level: simple peak normalization or RMS-based loudness matching, with optional soft limiting to stop clipping.

Runs 100% in your browser — your files never leave your device.

Notes

  • Peak normalization only guarantees the loudest sample; two files with the same peak can still sound very different. RMS matching tracks perceived loudness more closely.
  • Everything runs locally in your browser; your files are never uploaded to any server.
