What RoEx does
RoEx is a London-based AI audio technology company founded in 2022 as a spin-out from Queen Mary University of London's Centre for Digital Music, founded by David Ronan following his PhD research under Prof. Josh Reiss. The company builds AI-powered tools for automated multitrack mixing, mastering, and audio analysis, targeting independent musicians, bedroom producers, music technology platforms, and post-production houses. Its core product Automix analyses up to 32 multitrack stems and applies EQ, compression, panning, reverb, and level balancing to deliver release-ready mixes in minutes, while Mix Check Studio offers a free AI mix analyser with an optional Mastering+ upgrade. The Tonn API and SDK Suite allows B2B platforms to embed RoEx's capabilities, with documented integrations powering UnitedMasters Mastering and Music.AI across 15,000 organisations, alongside Yamaha Creator Pass distribution across 37 countries.
Underlying technology is purpose-built rather than wrapper-based: proprietary AI models trained in-house by professional audio engineers using music information retrieval techniques, deployed via a containerized API on Google Cloud Platform. RoEx maintains a clear responsible-AI stance, explicitly stating it does not use customer audio for training and that artists retain full ownership. The platform extends into the digital audio workstation ecosystem through Ableton Live Set Export and DAWproject support for Bitwig Studio, Fender Studio, and PreSonus Studio One, with Automix Desktop (Beta) providing offline local processing on Mac and Windows.
RoEx monetises through a hybrid model: tiered Automix Pro subscriptions at approximately $14.99/month, pay-as-you-go Mix Enhance credits at $4.99 per download, credit-pack top-ups, and enterprise licensing of the Tonn API and SDK. Distribution combines self-serve product-led growth through roexaudio.com with white-label and embedded OEM partnerships (UnitedMasters, Music.AI, Yamaha Creator Pass) and a 30% affiliate program targeting music bloggers and YouTubers. Customers include individual creators (1M+ self-serve users), distributors (UnitedMasters), music education (BIMM University), and emerging platforms (un:hurd, MNGRS.AI).

RoEx competitors and assessment
Company assessmentBroad incumbents
- Dolby: Dolby is a broad audio technology incumbent offering professional mastering, loudness normalization, and immersive audio (Atmos) tools that overlap with RoEx's mastering and spatial audio capabilities. It is referenced in RoEx's own data as supporting Dolby Atmos output formats.
- Waves Audio: Waves is a major professional audio plugin and processing company whose products are used in studios worldwide for mixing, mastering, and effects. It competes as a broad incumbent offering a wide portfolio of audio processing tools, including some AI-assisted features.
- iZotope: iZotope is an established professional audio tools company offering Neutron (AI-assisted mixing), Ozone (mastering), and RX (audio repair) — products that overlap directly with RoEx's feature set. As a broad incumbent with much larger scale and a professional user base, it competes both at the prosumer and professional mixing levels.
Emerging players
- Splice: Splice is a leading music production platform offering samples, plugins, and creator tools, with growing AI features for producers. It targets the same independent producer segment as RoEx and represents an emerging distribution channel and potential competitor in creator tooling.
- Moises.ai: Moises is an AI audio platform offering stem separation, mastering, and practice tools for musicians. It overlaps with RoEx on AI-powered audio processing for creators, and represents an emerging alternative in the broader AI-music-tools category.
Others
- Ableton: Ableton is a leading DAW manufacturer and a key RoEx partner (Ableton Live Set export integration). While not a direct competitor in mixing, Ableton's decisions about native AI features or partnership exclusivity could materially affect RoEx's distribution into the professional producer base.
- Music.AI: Music.AI is a platform partner of RoEx (distributing Tonn API to 15,000 organisations) but is also an emerging player in the broader AI audio infrastructure space, offering stem separation, transcription, and other AI audio APIs that overlap with adjacent categories.
Direct peers
- LANDR: LANDR is the leading AI-powered automated mastering service for musicians and producers, offering multitrack mixing and mastering similar to RoEx's Automix. It is a direct competitor founded by RoEx advisor Josh Reiss's co-founder, validating the category while posing the most direct competitive threat.
- eMastered: eMastered is an AI mastering service targeting independent musicians, songwriters, and producers — closely matching RoEx's Mix Check Studio and Mastering+ positioning. It competes on similar price points and customer segments, particularly for the bedroom-producer use case.
- Sonible: Sonible offers AI-powered audio plugins including smart:engine for automatic EQ, compression, and reverb — directly competing with RoEx's Automix in the AI-assisted mixing category. It serves a similar prosumer/producer audience and represents one of the most capable direct AI-mixing competitors.
