Quick Answer

LUFS (Loudness Units relative to Full Scale) measures perceived loudness over time—streaming platforms target roughly -14 LUFS integrated for Spotify and similar services, turning down louder masters and sometimes turning up quieter ones within limits. True peak caps prevent inter-sample clipping after encode. Mix for tone and dynamics; do not chase -14 on the mix bus with a limiter only. Plugg Supply lists free loudness meters via Telegram.

What LUFS Measures

Integrated LUFS averages loudness across the track; short-term and momentary help spot pumping. Different from peak dBFS.

What Normalization Does

Platforms attenuate hot masters to match target—extra limiter loudness does not equal more punch after normalize. Quiet masters may be gained up slightly.

True Peak and Codec Safety

Keep true peak below -1 dBTP before lossy encode to reduce decoder overs; LUFS and TP work together.

Mix Without LUFS Chasing

Balance instruments first; mastering sets final LUFS. Metering on mix bus for education OK, not for slamming.

Dynamics and Genre

Trap and EDM masters often louder than -14 before normalize; accept platform turn-down or master two versions for streaming vs DJ.

Free Loudness Meters

One Takeaway

LUFS tells you how loud playback will feel after normalize—use it to avoid pointless limiter wars, not to replace good mix balance.
