RoEx Automix
AI mixing and mastering for independent musicians
About
RoEx Automix takes uploaded stems and returns a mixed and mastered track, or masters a finished stereo mix on its own; mixing, mastering and previewing are free and you pay only to download. The tech comes out of mixing research at Queen Mary University of London, and a separate Mix Check Studio gives free diagnostic feedback on your own mixes. It is built for indie artists rather than professional engineers, the free download credit is limited, and per-track versus subscription pricing has varied, so confirm the current plans before subscribing.
