What is EBU R128 and why does it matter?

EBU R128 is the European Broadcasting Union standard for loudness measurement and normalization. It defines a target loudness of -23 LUFS (Loudness Units relative to Full Scale) and limits true peak to -1 dBTP. Most streaming platforms use variations of this standard (YouTube targets -14 LUFS, Spotify -14 LUFS, Apple Music -16 LUFS). Normalizing to these standards ensures your content sounds right on every platform.

What are the right levels for podcasts vs YouTube?

Podcasts: -16 LUFS (Apple Podcasts standard) to -14 LUFS (Spotify). YouTube: -14 LUFS (YouTube normalizes to this). Broadcast TV: -23 LUFS (EBU R128). Music streaming: -14 LUFS (Spotify, Apple Music). The tool uses -14 LUFS as a default since it works well for most online content.

Will normalization cause clipping or distortion?

The EBU R128 loudnorm filter includes a true peak limiter that prevents clipping. It analyzes the audio in two passes — first measuring loudness, then applying gain while ensuring peaks never exceed the safe threshold (-1 dBTP). This means your audio gets louder or quieter as needed without ever distorting.

Questions Fréquentes

What is loudness normalization?

It adjusts perceived volume to a consistent level using psychoacoustic models — not just peak levels. Prevents quiet dialogue followed by blasting music.

What is EBU R128?

The European Broadcasting Union standard for loudness. Targets -23 LUFS with -1 dBTP peak limit. YouTube uses -14 LUFS, Spotify -14 LUFS, Apple Podcasts -16 LUFS.

Podcast vs YouTube levels?

Podcasts: -16 LUFS (Apple standard). YouTube: -14 LUFS. Broadcast TV: -23 LUFS. Music streaming: -14 LUFS. The default -14 LUFS works for most online content.

Will it cause clipping?

No. The loudnorm filter includes a true peak limiter. It measures first, then applies gain while keeping peaks under -1 dBTP. Your audio adjusts without distortion.
