Normalize audio by peak level
Normalize audio to a target peak from −20 to 0 dB and download an adjusted WAV file. Free to use, with no sign-up required.
Files processed on your deviceAudio is decoded and processed in this tab at its original sample rate. Results are saved as WAV.
01 How it works
- Choose one audio file.
- Set a peak target from −60 to 0 dB.
- Download the normalized WAV.
02 Good to know
Peak normalization changes the overall level to meet the target; it does not make perceived loudness consistent across recordings. Browser codec support applies; each input is limited to 300 MB and three hours, with browser memory limits applying.
03What peak normalization changes
Peak normalization measures the highest sample peak and applies gain so it reaches the selected target, unless doing so would clip. It changes the whole file's level by the same gain; it does not even out quiet and loud passages.
Peak level is not perceived loudness. Two recordings with the same peak can still sound different in average loudness, so use this control for a peak target rather than loudness matching.
04Choose a peak target for audio normalization
Set the loudest peak between −20 and 0 dB, then download the normalized WAV. A silent file has no peak to raise. Inputs require a browser-supported codec and are limited to 300 MB and three hours, subject to browser memory.
05 Questions
Does peak normalization make two songs equally loud?
No. It matches their sample peak to a target, not their perceived loudness.
Can normalization clip the WAV?
The processor limits gain to avoid clipping. When the requested target would require unsafe gain, it uses less gain than requested.
