Audio normalizer

Scale an audio file so its loudest peak hits a target level, saved as WAV.

Decoded, scaled, and re-encoded as WAV in this browser. The audio never leaves your device.

Peak normalization — not loudness (LUFS) normalization, which needs a perceptual model this tool does not implement. Up to 10 minutes; output is 16-bit stereo/mono WAV (≈10 MB/min).

How to use

  1. Choose an audio file.
  2. Set the target peak in dBFS.
  3. Normalize and download the WAV.
