Bring a recording’s highest sample peak to a chosen level. Set a target in dBFS and apply a single gain change while keeping relative dynamics intact.

Set a peak target

Choose the target before processing. A setting such as −1 dBFS leaves sample-peak headroom below digital full scale.

Keep quiet and loud passages proportional

The tool measures the highest absolute sample value and scales the track uniformly. It does not selectively compress loud sections.

Separate peak level from perceived loudness

Two recordings with the same peak can sound very different in loudness. This is not integrated-LUFS normalization or a streaming-platform loudness preset.

Inspect noisy or silent sources

Raising a quiet track also raises its noise. A completely silent input remains silent because there is no meaningful peak to amplify.

Audio Normalizer FAQs

Not necessarily. Peak matching does not account for the duration or density of loud passages.
No. The target is based on sample peaks, not oversampled true-peak measurement.
Not necessarily. Two songs can share the same highest peak while having very different average levels and dynamics. This tool sets peak level, not integrated LUFS loudness. Use a loudness-metered workflow when a platform or broadcast specification requires a LUFS target.
Audio Normalizer schedules a background render after a setting changes. The completed preview or analysis replaces the previous result automatically. Processing time depends on recording length and device performance; the status message shows when the new result is ready.
