We carefully process your tracks using a combination of high quality analogue and digital tools, along with our own ST Mastering workflow. The goal is a clear, balanced and competitive master that translates on real world systems and meets current platform standards. Every project is treated individually so your final master is ready for release, not just run through a preset.
– 4 FINAL DELIVERY
When mastering is complete, we print your masters in real time through our full signal chain, not offline shortcuts. You receive a secure download link to your final masters in the delivery formats you need for release. Before sign off, you can review the masters and request any small adjustments, and we will refine and reprint where required. Every project is checked for consistency and translation across real world playback systems so you can release with confidence.
