RoEx Automix is an AI mixing service that turns uploaded multitrack stems into a balanced, release-ready mix in minutes. Mixing and mastering happen in one pass, so tracks meet streaming standards without learning complicated plugins or hiring an engineer. RoEx also offers Mix Check Studio for instant, objective feedback on a mix, plus the Tonn API and offline SDK for developers who want mixing, mastering and audio analysis inside their own products. Its research comes from Queen Mary University of London. Automix output is built around release readiness,; before and after audio examples demonstrate the difference.
Independent artists, bedroom producers, beatmakers and songwriters who know the basics but lack studio gear or budget are the core users. Retired and working engineers use it as a fast first pass, and composers use Mix Check Studio as a second pair of ears. Platform builders and enterprises can integrate the Tonn API for automated audio production. Music made with AI generators can also be polished here. Content creators using AI music generators such as Suno can polish those songs into something closer to a professional release. Educators and learners also use the feedback as a quick lesson in common mix problems.
Typical workflows include exporting stems from a DAW such as Ableton, uploading them for an automatic mix, then releasing to streaming services. Producers run finished mixes through Mix Check Studio to catch tonal balance or clarity problems before release, and can apply fixes with the optional Mastering+ upgrade. RoEx states that it does not train AI on customer music and that ownership of mixed tracks stays with the artist. Creators also use it to prepare tracks quickly for Spotify and other streaming services, and RoEx runs a community showcase of music mixed and mastered with its tools. A partnership with Yamaha provides access through Yamaha Creator Pass.
