About
RoEx is an intelligent audio production platform trusted by over one million artists and backed by research from Queen Mary University of London. Its flagship product, Automix, lets musicians upload multitrack stems and receive a professionally balanced, release-ready mix within minutes — no plugins, no studio time, and no engineering background required. The AI handles level balancing, panning, EQ, and mastering while ensuring output meets major streaming platform standards. Mix Check Studio is a complementary tool that provides instant, objective feedback on existing mixes and masters. It identifies issues like clarity problems, tonal imbalance, and dynamic inconsistencies using creator-friendly language. An optional Mix Enhance upgrade lets users apply AI-driven fixes automatically, making it ideal for producers who want actionable guidance before releasing a track. For developers and platforms, the Tonn API and offline SDK allow integration of RoEx's professional-grade audio analysis, mixing, and mastering capabilities directly into third-party apps and services. RoEx is built around responsible AI principles: user music is never used for AI training, and all ownership rights remain with the creator. With over 5 million tracks enhanced, the platform serves bedroom producers, independent artists, hip-hop beatmakers, and even seasoned studio engineers looking for speed and efficiency. Pricing follows a freemium model — analysis and previews are free, with payment required only at download.
