Frequently Asked Questions

What is a loudness penalty?
When your track is louder than a platform's target, it gets turned down. A track at -8 LUFS on Spotify (target -14) loses 6 dB — sacrificing dynamic range for no benefit.
What LUFS should I target?
For streaming, -14 LUFS is a safe target that works across most platforms. Master louder only for specific reasons like club play, where -8 to -10 LUFS is common.
How accurate are these penalties?
Penalties match official platform normalization algorithms. Results may vary by ±0.1 dB from streaming services due to codec differences in final delivery.
