Analyze and normalize audio volume with peak, RMS, and LUFS control, no upload.
The Audio Volume Normalizer measures peak amplitude, true peak (dBTP), RMS, and integrated loudness in LUFS following ITU-R BS.1770-4, then applies the gain needed to reach your target, with a limiter that holds transients under the true-peak ceiling. You can hear the before and after at matched loudness before downloading. Everything happens in the browser via the Web Audio API, without sending data to servers.
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

Peak normalization increases or reduces the overall gain of an audio file so that the maximum peak amplitude reaches a defined target level, usually -1 dBFS to avoid clipping on playback systems. It is the simplest and most direct normalization method.
