We’re a team of sound engineers, music makers, academics and developers, united by a passion for music, and a shared vision to transform how it’s produced.
RoEx's Products
Automix: the first-to-market automated mixing platform. Automix is designed to produce professional-grade mixes and masters in just minutes - saving time and unleashing creativity.
Mix Check Studio: delivers instant, actionable feedback on work-in-progress mixes and masters. Mastering+ then uses this feedback to improve vocal clarity, enhance drums, balance tone, and resolve loudness issues.
Tonn API Suite: empowers enterprise partners by integrating RoEx's advanced audio capabilities (including mastering, multitrack adaptive mixing, mix analysis and clean up) into their own platforms. An example partner integration is UnitedMasters Mastering, powered by RoEx.
RoEx is driving innovation in how audio is produced and consumed worldwide, with cutting-edge AI trained by professional audio engineers. Our game-changing innovations include: Mastering+, enabling music makers to improve their audio without needing original stems, and Automix’s integrations with Ableton Live and DAWproject, which let producers achieve an AI-assisted, balanced mix and then refine the settings in their DAW.
The future of music is here. Let’s create it together.
Meet The Team
David Ronan - CEO and Founder
Meet David Ronan, the visionary behind RoEx. With a clear and ambitious goal in mind, he set out to simplify and enrich the music creation process for artists at all levels. David founded RoEx, drawing inspiration and early support from his academic mentor, Prof. Josh Reiss.
David holds a PhD in Electronic Engineering and Computer Science from the Centre for Digital Music at Queen Mary University of London. Under the mentorship of Prof. Josh Reiss, one of the original founders of LANDR and a leading figure in the field, David focused his research on intelligent audio production tools. This academic journey allowed him to delve into the intersection of technology and music, laying the groundwork for what would later become RoEx.
During his academic years, David took a brief hiatus to work in the research department at Native Instruments in Berlin. Intrigued by his PhD work, the team there provided him with practical experience that enriched his academic insights.
Prior to launching RoEx, David led the research team at AI Music for approximately 4.5 years. The team was dedicated to advancing the field of adaptive music, and their innovative work caught the attention of Apple, leading to an acquisition. This milestone served not just as a career highlight, but also as a validation of years of hard work and innovation.
