LUFS Loudness Meter
Measure integrated, short-term, and momentary loudness using BS.1770-based weighting and gating, plus sample peak and loudness range.
What this tool tells you
What it does
Use this when you need a browser-local loudness readout for a mix, master, episode, or other audio file.
How to use it
Open one file and let the meter analyze the decoded audio. Review integrated loudness for the whole file, then use short-term and momentary values to examine changes over time.
How to interpret it
Results come from the TrueRes BS.1770-based implementation and are useful for comparison and production checks. Confirm any delivery requirement against the current specification from the destination service or distributor.
