What audio normalization does

Normalization measures the peak amplitude of your audio and applies a single gain adjustment so the peak hits a target level. Unlike a limiter, it doesn't change dynamics — it just scales everything proportionally. Useful for matching loudness across files before mixing.

Peak vs LUFS normalization

This tool does peak normalization, which targets the loudest single sample. Streaming platforms use LUFS normalization, which targets perceived loudness across the whole track. For LUFS-targeted mastering, see our LUFS Standards reference.
