Online Mastering
Professional mastering services from a Billboard-charting engineer. Get that
polished, radio-ready sound for your finished mix.
What is Online Mastering?
Online mastering is the final step that transforms your mix into a release-ready track. It goes beyond EQ, compression, and loudness — it’s about creating balance, depth, and polish so your music connects with listeners on every platform.
At the helm is mastering engineer Matty Harris, whose experience with major artists and independent musicians ensures your music is treated with the same care as top-charting records. Matty works with you directly to refine your unique sound and make sure your tracks stand out worldwide.
Our mastering suite blends the best of both worlds: the warmth of analog hardware from Bettermaker and Avalon, combined with the precision of cutting-edge digital tools. The result is a master that’s loud, clear, and ready for Spotify, Apple Music, and beyond.

Frequently Asked Questions
What’s the difference between stereo and stem mastering?
Stereo mastering works with your final mix as one stereo file. Stem mastering uses 2-5 separate groups (vocals, drums, bass, instruments, etc.) for more precise control during the mastering process.
How should I prepare my mix for mastering?
Export your final mix as a WAV or AIFF file at the same bit depth and sample rate as the mix. Leave about -3 to -6dB of headroom (don’t let it clip or hit 0dB). Remove any limiters or mastering plugins from your master channel. If you were using a limiter, please send a screenshot for reference.
How long does mastering take?
Typical turnaround is 2-4 business days. Revisions are usually completed within 24-48 hours. Need it faster? Contact us about rush service availability.
