Roex

What is Roex?

RoEx is an AI-powered audio production platform that automates mixing and mastering for music creators, made by a team combining research from Queen Mary University of London with professional studio expertise.

The platform offers two core products. Automix accepts multitrack stems and delivers a mixed and mastered track in minutes, handling level balancing, panning, and audio processing without requiring users to own a studio or learn complex mixing software. Mix Check Studio provides objective feedback on finished mixes or masters by analyzing technical issues like clarity, frequency balance, and tonal problems, with an optional Mix Enhance feature that applies intelligent corrections automatically. Both products retain full user ownership of uploaded music—RoEx does not train models on creator content. The Tonn API and SDK enable developers to integrate RoEx's audio processing capabilities into third-party platforms and services.

RoEx serves bedroom producers, independent artists, and established engineers. The platform claims over 1 million users and has processed 6.5 million audio tracks. It partners with Yamaha through the Yamaha Creator Pass subscription program. Testimonials highlight adoption by electronic producers, hip-hop beatmakers, and ambient composers who appreciate the speed and objective analysis without human bias. The service works with stems from common DAWs including Ableton, and users report releasing mixed tracks directly to Spotify and streaming platforms.

Pricing operates on a subscription model with tiered plans for individual creators and enterprise licensing for API access. Free trials of Mix Check Studio allow users to test analysis features before commitment. The affiliate program offers revenue sharing for referrals.

Similar competing tools include LANDR (mixing and mastering AI), BeatConnect (audio analysis), and Cloudbounce (automated mastering), though RoEx emphasizes its research backing and privacy guarantees around
