About this tool

Loudness Meter measures integrated loudness in LUFS to the EBU R128 standard, plus sample peak in dBFS, for producers preparing masters or checking how a platform will normalise them.

The measurement runs in your browser on the decoded file and is shared with every other SKELETUNE tool, so it never runs twice for the same file. This screen reports numbers only and never changes your audio.
