LUFS (Loudness Units relative to Full Scale) is the standard loudness measurement used by all major streaming platforms. Unlike dBFS (peak), LUFS measures perceived loudness — how loud your track actually sounds to human ears. Spotify normalizes to -14 LUFS, YouTube to -13, and Apple Music to -16. If your track is louder than the target, the platform will turn it down. If it's quieter, they may turn it up (or leave it).
| Platform | Target LUFS | True Peak Limit |
|---|---|---|
| Spotify | -14 LUFS | -1 dBTP |
| YouTube | -14 LUFS | -1 dBTP |
| Apple Music | -16 LUFS | -1 dBTP |
| Tidal | -14 LUFS | -1 dBTP |
| Amazon Music | -14 LUFS | -1 dBTP |
If you master at -8 LUFS (very loud), Spotify will turn your track down by 6 dB to meet -14 LUFS. This means your loud master actually sounds quieter than a properly mastered track at -14 LUFS — and it may lose punch after normalization. The fix: master to the platform target, not louder.
