Loudness Tool
Adjust gain and normalize the recording’s peak level, then preview and export MP3 or WAV locally in your browser.
Peak normalization applies a common gain to the whole recording. It does not automatically make each quiet and loud passage equally loud. A file with the same maximum peak as another file can still sound quieter overall.
Boost amount is applied after normalization. Turning it up can push samples into clipping when the limiter is off. The soft limiter shapes sample levels and can change the sound; it is not a transparent repair for distortion already in the source. Gain also raises existing noise.
This tool does not target an integrated LUFS value, automatically level speech within a recording or certify a true-peak delivery limit. Use the Loudness Analyzer to inspect a version, then follow your destination's requirements with an appropriate final check.
Read how sample peaks and LUFS differ and how to boost quiet audio without harsh clipping. Keep the original file and compare your exported copy before sharing it.
About This Tool
Peak normalization scales the whole recording, then Boost amount applies further gain. The optional soft limiter shapes sample levels and can change the sound. This is not automatic speech leveling or target-LUFS normalization.
No. It can raise level and control new clipping, but distortion already present in the source remains.
It scales the source so its highest sample peak is 96% before Boost amount and the optional limiter are applied. Those settings change the final peak. It does not level individual passages or target LUFS.
