Important note on the Master Subscription.
This subscription is built for artists and labels who want ongoing mastering support and long-term collaboration.
The pricing reflects a considerable saving compared to standard per-track mastering and is intended for continued use over multiple months, not short-term, one-off, high-volume projects.
If you’re looking to sign up for a single month, upload a large batch of tracks, and then cancel, this subscription isn’t the right fit. In those cases, standard mastering services are more appropriate.
By signing up, you’re committing to a working relationship built on fairness, consistency, and mutual respect.
