Not presets
Two hip hop records should never get the same treatment. The engine measures what actually arrived, compares it against the sound it learned from thousands of finished masters, and decides from there. Genre sets the target. The song sets the moves.
Sub sat 1.9 dB above the target for this genre, so it came down 1.9 dB at 34.6 Hz.
Low band held 0.95 dB, mids 0.53 dB, top 0.51 dB. Glue, not flattening.
Correlation 0.87. Width left at 1.0 and everything below 120 Hz kept mono.
Console character at 1.0 dB of drive. Harmonics added at -47.5 dB.
-14.0 LUFS integrated, -1.0 dBTP ceiling. Clean through Spotify normalisation.
Most AI mastering hands you a file and a shrug. This one hands you the reasoning, in the same plain language a mastering engineer would use on the phone. If you disagree with a call, you can see exactly which one to change.
You stay in charge
The engine sets every technical value underneath, then gives you the words you actually think in. Push the vocal up. Make the low end massive. Take the reverb off. Preview in seconds, apply to the full song when it is right.
The part nobody else does
Every change you make teaches it something. Not one slider nudge, that is just a decision about one song. But the same move across three songs becomes a preference, and your next upload starts there instead of at the default.
Louder vocals. Drier reverb. Heavier low end. Stronger tuning. Each preference carries a confidence score you can see, edit or delete at any time.
A Caribbean engineer for soca and dancehall. An urban one for trap and R&B. Different rooms, different habits, each learning separately.
"I started this mix with your usual louder lead vocal, reduced reverb and warm low end, based on your last projects."

FAQ
One stereo WAV is enough. If you have the session, upload stems and you will get a better result, but it is not required.
Minutes. Separation is the slowest part and usually finishes in under two.
There is no single fixed number. The engine measures what actually arrived and sets the target from the song itself, its genre and any reference you give it, so a sparse ballad and a dense club record are not pushed to the same place. Most streaming releases land around -14 to -9 LUFS with a true peak ceiling held safely under 0 dBTP. You can still name a target yourself, and there are presets for Spotify, Apple Music, club and broadcast.
Yes, unlimited. Autotune, compression, reverb, delay, vocal level and a five band EQ. Nothing is mastered until you push it to mastering yourself.
The full instrumental with backing vocals kept in and the lead vocal removed, for live shows and television.
Your projects stay in your account so you can come back to them. We never train on your audio unless you opt in, and we never sell or license it.
