Master your track with AI — and actually see what it's doing.
Mixee turns rough mixes into streaming-ready masters with a realtime spectrum analyzer, a 24-band EQ, quality warnings and optional stem-based control.
Tuned for the platforms that pay you
Why Mixee
Most AI mastering is a black box. Mixee isn't.
You don't just get a louder file — you see exactly what changed and why.

Loud where it counts. Honest everywhere else.
Mixee is built on the same principles a mastering engineer would follow: protect the mix first, push loudness second, and tell you when something is off — instead of silently squashing it.
True-Peak safety, every time
Two-pass loudnorm + dedicated true-peak limiter. Ceiling never crosses −0.8 dBTP.
Dynamics-first, loudness-second
Mode-aware clamps cap compression and limiter activity to mastering-safe ranges.
Smart Quality Warnings
Post-render analysis flags issues with severity and a plain-language fix.
Realtime preview = final render
What you hear in the browser is the same DSP chain (and clamps) the server applies.
Your next release deserves a real master.
