RoEx Mastering is an AI-powered mastering service for musicians, producers, and independent artists working from stereo mixes. It analyzes a mix and applies equalization, multiband compression, limiting, stereo refinement, loudness normalization, and true-peak-safe processing. Users can choose genre profiles, preview results, compare versions, adjust the result, and download mastered files. The service accepts WAV, FLAC, and MP3 files and supports mastering through the web, with local offline processing available through Automix Desktop on macOS.

Its strongest area is control around the final master. Genre profiles cover Electronic, Hip-Hop, Rock, Acoustic, Pop, and Orchestral music, while loudness targets are available at approximately -9, -11, and -14 LUFS. Reference-track matching in the Pro workflow can align tone, dynamics, stereo image, and loudness with a chosen reference. A/B comparison and result tweaking provide a way to review alternatives before download, rather than relying on a single fixed output. These tools make RoEx a suitable choice for creators who want more direction than an entirely automatic preset.

RoEx uses a paid model with no free plan, although free previews are part of the workflow before paid mastering downloads. Export options include WAV, FLAC, and MP3, and Automix adds mobile track and batch mastering alongside the macOS desktop beta. The product is a good fit for artists who prioritize genre-aware mastering, reference matching, loudness control, and offline processing. It is less suitable for workflows built around stem mastering, since the published feature set centers on stereo mixes. Buyers who need a straightforward stereo mastering service with selectable targets should consider it; those requiring stem-based processing should choose an alternative.
