Why one button.
Making an album is a thousand choices. Composition, takes, mix, arrangements. You reach mastering exhausted. And there, you're offered even more choices: presets, intensity levels, sliders. As if it were a new mixing phase.
That's not what mastering is. It's the closure. Someone tells you: your mix is ready, here's the final version. Now it's yours to release.
That's the role mastering engineers have held for fifty years. That's the role we take here. Not one more piece of software, not one more subscription. An end to the loop.
An engine built without artist data.
No track, no mix, no artist's work was used to build our engine.
It's not a model imitating what humans have done. It's an engine doing what mastering is meant to do.
Your music stays your music. So does everyone else's.
