About the LUFS Loudness Meter for Spotify & YouTube
Completely free: free account, no credits, no limit. It runs in your browser, so your audio stays on your device.
The LUFS Loudness Meter measures integrated loudness the standard way (ITU-R BS.1770 / EBU R128: K-weighting, 400 ms blocks, absolute and relative gates), plus the loudest 3-second stretch and the sample peak.
It then shows what streaming services will do: Spotify, YouTube and Tidal play music at about −14 LUFS by default and Apple Music at about −16, turning louder songs down. One click makes a −14 LUFS version with a limiter at −1.5 dB.
The peak shown is the sample peak, not the oversampled true peak, so leave about 1 dB of headroom.
What you can use it for
- ✓Check a master before uploading to Spotify or a distributor
- ✓Compare your mix with a reference track
- ✓Bring a quiet podcast or video soundtrack up to a standard level

Frequently asked questions
How loud should my song be for Spotify?
+
Spotify normalises to about −14 LUFS integrated, so a master around −14 to −9 LUFS with peaks below −1 dBFS plays well. Louder masters are simply turned down.
What is LUFS?
+
Loudness Units relative to Full Scale: a measure of how loud audio sounds to people, not just its peak level. Streaming services use it to play every song at a similar volume.
Is the result the same as in my DAW?
+
Integrated LUFS follows the same standard, so it should agree within a few tenths. The peak here is the sample peak, which can read slightly lower than a true-peak meter.
Is it really free?
+
Yes. It is completely free, with a free account: no limit and no watermark. It runs in your browser, so your audio stays on your device.
