Mix Check Studio

Mix Check Studio is an AI mashup maker tool. A free browser based AI mix analyzer from RoEx that reviews uploaded tracks for EQ, dynamics, loudness, stereo width and clipping, with paid Mastering+ options for automated enhancement and release ready audio.

Mix Check Studio is a browser based audio analysis tool built by RoEx that reviews mixes and masters and returns structured feedback on the technical side of a song. A creator uploads a WAV, FLAC or MP3 file (up to 173MB) and the system reports on EQ balance, dynamics, integrated loudness, stereo width and clipping. The premise is simple: an automated second opinion that does not get tired, has no genre bias and no off day. The site reports more than 1.1 million tracks checked to date, and states that uploaded music is not used to train models. The product covers four modes. Check is the free analysis pass and the core of the tool: it produces the feedback report a producer would otherwise need a fresh pair of ears for. Revive targets older recordings that need restoring. Enhance works at stem level to correct problems in a mix or master you already have. Master is the release oriented pass, sold as Mastering+ and billed per download at $6.49 or included without limits in Studio Pro at $12.99 per month. That split matters: analysis is the free entry point, while automated correction and release ready audio sit behind payment. Practically, the tool suits self recording artists, beatmakers, mixing engineers and anyone releasing music without a mastering budget. The workflow is iterative. Upload, read the report, adjust the mix in your DAW, then re-upload to compare. Reviewers on the site describe exactly this loop, including one artist who remixed a track three times and rechecked it before distribution. Because the analysis is objective and preference free, it works well as a pre-release sanity check rather than a creative director. Against alternatives, Mix Check Studio is narrower than a full mastering suite like Ozone and lighter than a DAW ecosystem like BandLab. It also markets itself toward AI generated music, offering to analyze and improve Suno tracks that sound flat next to commercial releases. Where LANDR and similar services push straight to automated mastering, this tool leads with diagnosis and treats correction as a paid add on, which makes it a reasonable fit for producers who want to learn from the feedback rather than hand over the final decision.
