Mastering is the final quality check and preparation of your audio before distribution. It ensures your music:
Sounds great across all devices and platforms.
Feels cohesive and polished, with clarity and impact.
Meets loudness standards for Spotify, Apple Music and more.
Even if you’ve mixed your own track, mastering acts as a second pair of expert ears - balancing the tone, refining loudness, and preparing your music for release.

How It Works
AI Mastering can provide quick and consistent results.
Genre-Aware Settings
Our audio engine adjusts mastering style based on the musical genre - because techno and folk don’t sound the same.
Loudness Flexibility
In Automix you can choose between optimised ‘medium’ loudness for streaming platforms, or a maximised, punchier output.
Tailored Processing
Behind every mastered track is a series of measured adjustments: EQ, dynamic shaping, stereo width, loudness normalisation, and peak limiting. This processing is made with intention, not guesswork.
Reference Matching
With Automix Pro, you can match your master to the sonic profile of a track you admire. Our Reference Match feature intelligently aligns your audio’s tone, dynamic range, stereo image, and loudness to your chosen reference track.
Our Mastering Engine was built by audio engineers, backed by pioneering research from Queen Mary University of London. Unlike tools that rely on presets or black-box models, RoEx takes a fundamentally different approach:
Manual training by audio engineers to emulate real-world mastering workflows.
Measurements over assumptions: We analyse your track’s frequency balance, dynamics, and stereo field before it’s mastered.
Purpose-built DSP systems developed from our academic backgrounds in audio engineering and music technology.
Trusted by music makers who care about their sound: Our technology has been used on over 3 million audio tracks to date.

Your music is yours, and we treat it that way. The ownership of your music remains unchanged when you use Automix or Mix Check Studio.
We never use your tracks for model training or future AI refinement.
