Loudness Units relative to Full Scale measure integrated perceived audio loudness over time under standardized weighting.

Will increasing volume remove noise?

No. Gain also raises background noise; use a dedicated noise-removal workflow when appropriate.

How do I avoid clipping?

Use a controlled limiter or loudness normalization with a true-peak ceiling rather than blindly boosting by a large amount.

THE WORKFLOW, EXPLAINED

How to normalize audio volume online

Upload an audio file and preview the source.
Choose Gain or Loudness Normalization, a target level and peak ceiling.
Render, compare the output at matched listening conditions and inspect peaks.

Peak level is not perceived loudness

Decibels of gain change signal amplitude; LUFS measurements better approximate average perceived loudness. Loudness normalization can require dynamic processing and peak limiting to prevent clipping. No automated setting fixes a severely distorted recording. This workspace uses browser-local media codecs for output creation. First-time processing may require downloading a sizable WebAssembly engine; conversion speed, available encoders and supported formats depend on the device, source file and browser. Review the exported video or audio before relying on it professionally.
