Loudness

Streaming (−14 LUFS) Best for Spotify, Apple Music and YouTube. Recommended. Quieter (−16 LUFS) Keeps the most dynamics. Loud (−9 LUFS) Much louder, but the limiter has to work hard, so drums can pump or flatten. Streaming apps turn it back down anyway.

Sound

Style optional

Style strength: Medium (50%)

Strength: Off = no character moves, Subtle 10%, Light 30%, Medium 50%, Strong 70%, Full 100%. Each starts at its tested default (the small tick under the slider).

Mastering

Hear your mix mastered while you work on it. Pick a loudness and a style; Pauly masters the whole song (about 30–60 seconds for a long song) and the player switches to the master. Change anything and it updates; the last master keeps playing until the new one is ready.
