Reference

The number, and who says so.

What each territory and platform actually requires, read out of the standard itself rather than summarised from another summary. Every page says where its figures came from and links the document, so you can check us. If you want the explanation rather than the lookup, the loudness guide covers why these numbers differ.

The measurement

BS.1770-5ITU-R BS.1770 — The Measurement Underneath EverythingWhy LKFS and LUFS are the same unit, what the gate actually does, and which revision is in force.Read the spec

By territory

−23.0 LUFSEBU R 128 — European Broadcast LoudnessThe European broadcast target, with the tolerances and the Loudness Range caveat that the summary tables leave out.Read the spec

By platform

−14 LUFSSpotify — Loudness NormalisationNormalised to −14 LUFS, but the listener can move it to −11 or −19 — and what happens then is not symmetrical.Read the spec

Delivering somewhere that is not listed?

Send the spec sheet. We’ll measure every deliverable against it individually and send the report back with the files — and if the territory belongs on this page, it gets added.
