Frequently Asked Questions

Common questions about the free online audio volume normalizer.

Choose a file, pick peak or even mode, set a target level in dBFS, then click Normalize and download WAV.
Peak mode scales the whole file by one factor. Even mode adjusts short frames so quiet passages are lifted and loud ones are tamed.
Minus one dBFS is a safe peak target for music. For spoken word, around minus eighteen dBFS works well as an average level.
Only if there is headroom. If the loudest sample already sits at the target, the gain stays at one and nothing changes.
Peak mode never clips because the gain is measured from the loudest sample. Even mode limits its gain and trims the result if needed.
No. Normalizing only changes levels, so quiet background noise is lifted along with the rest of the recording.
Browsers cannot encode MP3 or OGG, so the processed samples are written out as uncompressed 16-bit WAV audio.
No. The whole analysis and gain change happens locally in your browser using the Web Audio API.
