LUFS Loudness Penalty Inspector.

Identifies if your audio master is too loud, calculating the exact decibel (LUFS) penalty Spotify, Apple, and YouTube will secretly apply to crush your track dynamics.

## The End of the Loudness War

For 20 years, mastering engineers used heavy limiters to crush music so it sounded "louder" than the next song on the radio. Today, streaming algorithms like Spotify actively punish loud masters by systematically turning down their volume via "Loudness Normalization."

### FAQ

**Q: Why do my heavy tracks sound quiet on Spotify?**
A: Because you pushed them to -8 LUFS. Spotify enforces a universal limit of -14 LUFS. If you hand them a track at -8 LUFS, Spotify's engine secretly applies a -6dB attenuation to your file. Not only is your song no longer "louder" than anyone else's, but because you artificially squashed the dynamic transients using a limiter to reach -8 LUFS, your song now sounds flat and lifeless compared to a proper -14 LUFS master that retained its natural punch.
