AI mix + master
AI mixing and mastering, online and in your browser
MixTrackLab is a full mix and master chain that runs locally in the browser. It listens to your stems, measures what is actually wrong, and corrects it the way a mix engineer would — instead of applying one fixed preset to every song.
Desktop recommended · phones work for listening and quick edits, but the full console, meters and fastest renders are on a laptop or computer.
The workflow
- STEP 1
Upload
Drop a folder, a zip of stems, or a vocal plus beat. Files stay on your device.
- STEP 2
Analyze
Every stem is measured for level, spectrum, crest factor, noise floor, key, and pitch.
- STEP 3
AI mix
Balance, carving EQ, ducking, and vocal chains are applied from the measurements.
- STEP 4
Master & export
Pick a mastering signature, run the quality check, then export 24-bit WAV.
It measures before it processes
Each stem is analyzed for integrated loudness, true peak, crest factor, spectral balance, noise floor, and masking against the other stems. Moves are only made where a measurement says a move is needed, and every move is logged so you can see it.
The beat is treated as the anchor of the mix. Instrumental energy is protected, so vocals are lifted into place rather than the beat being pushed down until the song loses weight.
Stems, or just vocal and beat
Full drum, bass, melody, FX and vocal stems get grouped and bussed automatically. If you only have a vocal and an instrumental, the engine detects an already-mastered beat and leaves it alone, adjusting level instead of re-processing it.
You keep control
Nothing renders until you press Mix or Master. Manual fader, EQ, and chain changes are remembered and re-applied after every AI pass, and A/B auditioning is loudness-matched so louder never sounds better by accident.
