What types of projects do you accept for mixing and mastering?

Projects are accepted selectively based on artistic quality, technical readiness, and alignment with my workflow. I work with artists, producers, and labels seeking translation-accurate, professional results rather than high-volume or template-based processing.

Do you offer revisions?

Yes. Revisions are part of the process and are handled thoughtfully to ensure the final mix or master meets the agreed artistic and technical goals without compromising translation or integrity.

What formats do you deliver for mastering?

Masters are delivered in all required formats, including high-resolution digital, streaming-optimized files, vinyl pre-masters, and broadcast-ready versions when needed.

Can you work with remote clients?

Yes. I work with clients worldwide. Files are exchanged securely via trusted transfer services, and all communication is handled directly to ensure clarity and efficiency.

Do you provide mix consulting or second opinions?

Yes. Mix consulting and second-opinion reviews are available for projects that need targeted feedback or corrective direction before final delivery.
