Frequently asked questions

What LUFS should I master to for Spotify?

Around -14 LUFS integrated is the target Spotify normalizes to, and Apple Music, YouTube, TIDAL, Amazon, and Deezer each sit at their own level. The meter measures your track with the BS.1770 standard and shows how much every one of those platforms will turn it down. Mastering louder than the target doesn't make you louder on streaming, it just earns a bigger penalty.

What is a loudness penalty?

It's how many dB a streaming platform turns your track down to match everything else in a listener's queue. A track measured at -8 LUFS gets roughly 6 dB taken off it on Spotify, so all the loudness you fought for in mastering disappears. What survives the turn-down is your dynamics, not your level.

Is LUFS the same as the dB reading in my DAW?

No. Your DAW's peak meter shows the single loudest instant in dBFS, while LUFS measures perceived loudness averaged over the whole track and weighted for how ears actually hear. A track can peak at 0 dBFS and still measure quietly in LUFS, which is why streaming services normalize by LUFS.

Can it fix the loudness for me?

Yes, it can normalize the track to a target loudness and export it. Understand what that does, though: it changes the level, not the mix. It won't tighten a master, and if your track is already squashed, turning it down leaves it squashed and quieter.
