RoEx Automix vs MixTrackLab (2026): Two Tools That Mix From Stems
Quick answer: RoEx Automix and MixTrackLab are among the smaller group of AI tools that actually mix, not just master. RoEx works from stems exported from a DAW. MixTrackLab accepts stems too but is built around a vocal and a beat, with vocal cleaning and pitch tools in the same studio. Both let you preview before you pay.
Desktop recommended · phones work for listening and quick edits, but the full console, meters and fastest renders are on a laptop or computer.
What they have in common
Both accept separate files instead of only a finished stereo mix, balance them, then master the result. That is the main difference from a mastering-only service. AI mixing vs AI mastering explains why it matters.
What each one says about itself
RoEx Automix states that it mixes and masters from up to 32 stems, offers free previews and one free mix download, and sells a Pro plan at $24.99 a month. It asks for stems exported from your DAW.
MixTrackLab. MixTrackLab works in the browser. You upload a vocal and a beat, or a set of stems, and it cleans the vocal, balances it against the instrumental and masters the result. You can mix, master and preview for free and pay only to export: $9.99 for a single song, or Studio Pro at $29.99 a month for six songs, or $249.99 a year for unlimited exports. Prices are in US dollars.
Who each suits
- You work in a DAW and export clean stems: either tool can work. Compare the previews on the same song.
- You have a vocal and a beat, recorded on a phone or USB microphone: MixTrackLab's vocal cleaning, tuning and genre profiles are aimed at that case.
- You release rarely: a single-song price can beat a monthly plan; check each side's current pricing.
How to hand over the right files: prepare stems for online mixing.
How to compare them fairly
Run the same song through both free previews. Listen on headphones, a phone speaker and in a car. Check that the vocal is clear, the low end is not muddy, and nothing sounds harsh. Then compare what it costs to export. How to use reference tracks shows how to judge the result.
