What mastering actually does

Mastering is the last creative step before release. It is not remixing. It works on the stereo mix as a whole, gently correcting tonal balance with EQ, tightening dynamics with compression and limiting, shaping the stereo image, and raising the overall loudness to a target level. Done well, it makes a track sound finished, consistent, and ready to sit next to commercial releases.

Mastering also targets a loudness standard measured in LUFS. Streaming platforms normalize toward around -14 LUFS, so a good master lands near that level for its genre rather than being pushed as loud as possible.
