Normaliser lydstyrke
Jevn volum (LUFS)
Om dette verktøyet
Even out the perceived loudness of an audio file so quiet sections become audible and loud peaks stop clipping or startling the listener. Privvert applies EBU R128 loudness normalization through FFmpeg's loudnorm filter - the same standard used by the BBC, Netflix, Spotify and most podcast networks.
The default target is -16 LUFS integrated loudness with a -1.5 dBTP true peak ceiling, which is the recommended target for podcasts and voice content. Switch the preset to match streaming music (-14 LUFS) or EU broadcast (-23 LUFS) when you need it. Everything happens locally in your browser.

-16 LUFS is the de-facto standard for podcasts and YouTube voice content. -14 LUFS matches Spotify, Apple Music and Tidal. -23 LUFS is the EU broadcast standard (R128). Pick the one that matches where the audio will be played.
Peak normalization just scales the loudest sample to 0 dB - it doesn't account for how the human ear perceives loudness. EBU R128 measures perceived loudness over the entire file, so quiet podcasts and loud music end up sounding equally loud to the listener.
No - the true peak ceiling (default -1.5 dBTP) prevents intersample peaks that would clip in some decoders.
Loudnorm in dynamic mode applies gentle compression to hit the target. Use linear mode if you want to keep the original dynamic range and only adjust gain.
