LUFS Meter FAQ

What is LUFS?

Loudness Units relative to Full Scale: loudness measured the way ITU-R BS.1770 defines it, weighted for how we hear and gated so silence doesn't count. Streaming services and broadcasters use it to set playback levels.

How many LUFS should my song be?

Most streaming services play music at about −14 LUFS, some at −16. Louder masters are turned down, so there is little to gain above that. Keep true peaks at −1 dBTP or lower.

Is this LUFS meter free and private?

Yes. It is free with no sign-up, and the file is measured in your browser: nothing is uploaded.

Is LKFS the same as LUFS?

Yes. LKFS (used in US broadcast standards) and LUFS are the same measurement, and 1 LU is 1 dB.

Can I change the loudness here too?

Yes. Normalize the file to your target with a true-peak limiter and download WAV, MP3 or AAC.
