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 target does this tool use?

The tool targets -14 LUFS integrated loudness with a -1 dBTP true-peak ceiling and a 11 LU loudness range — the de-facto standard for YouTube, Spotify, and most streaming platforms. Podcasts and TV broadcast targets (-16 / -23 LUFS) are not currently selectable; if you need those targets, post-process with Audacity or a DAW.

Will normalization cause clipping or distortion?

The loudnorm filter runs a true-peak limiter that keeps output under -1 dBTP. Note that the tool uses single-pass loudnorm — it estimates loudness on the fly rather than doing a two-pass analysis, so results are slightly less accurate than broadcast-grade tools but stay within the target ceiling without distortion.

Why this normalizer is different

The workflow is tuned for spoken audio, where consistency matters more than loudness hype.
Pairs naturally with silence removal and video audio replacement.
Runs locally, so interviews, classes, client calls, and legal recordings do not need to upload.

Task-focused FAQ

Does normalization remove background noise?

No. Normalization changes loudness. Noise, echo, and room tone need separate cleanup tools.

Can normalization fix clipped audio?

No. If the source is clipped or distorted, normalization cannot restore the lost waveform.

Should I normalize before or after cutting silence?

Remove long silent gaps first, then normalize the final audio for a more predictable level.

Frequently Asked Questions

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.

What target does the tool use?

Fixed at -14 LUFS with a -1 dBTP ceiling — matches YouTube, Spotify, Apple Music, and most streaming platforms. Podcast (-16) and broadcast (-23) targets are not currently selectable.

Will it cause clipping?

The loudnorm true-peak limiter keeps output under -1 dBTP. The tool runs single-pass so results are slightly less precise than a two-pass broadcast-grade measurement, but stay safely within the ceiling without distortion.
