Loudness Normalization Planner

Calculate gain, peak headroom, and likely limiter need from measurements. This tool does not decode, measure, limit, or modify audio.

Plan settings

Normalization mode

Illustrative preset

Target integrated (LUFS)

Maximum true peak (dBTP)

Preset caveat: Platform targets are illustrative planning examples, not promises of playback behavior. Services change policies, may use different measurement versions or device modes, and can turn normalization off. Verify current official delivery guidance before mastering.

A limiter flag means the requested loudness gain exceeds peak headroom. Applied gain is peak-limited for planning; reaching both targets would require dynamics processing and remeasurement.
