Mix Check Studio

The core Check tool runs your track through a model trained on real releases and returns feedback within seconds. It scores EQ balance, compression and loudness all at once, so you see the whole picture instead of chasing one meter at a time. That speed is the point: you can iterate on a mix and re-run the check between bounces.

Mastering+ is the optional enhancement pass, and it's the AI mastering layer that turns a report into a finished track. It applies adaptive EQ, compression, stereo imaging and limiting to an existing stereo file to lift clarity, loudness and width. You don't need the original multitracks. That's the difference between a five-minute job and reopening a whole session.

The analyzer shifts its reference targets based on what kind of music you're making. A jazz track and a trap track shouldn't be measured the same way. Mix Check Studio doesn't pretend otherwise. Selecting your genre is what makes the loudness and tonal feedback meaningful rather than generic.

A loudness check runs against streaming targets, so you learn whether a master will play back quieter than everything around it in a playlist. For artists releasing straight to Spotify or Apple Music, that matters more than any EQ tip. A hot master gets turned down anyway. Why push for extra headroom that platforms will throw away?

The tool reports on stereo width and imaging, catching mixes that collapse toward mono or push the sides too hard, which is genuinely hard to judge in a treated room, let alone on earbuds. An automated read helps. If your mix sounds thin on a big system, this is usually the first place to look.

The Check feature costs nothing and doesn't require signup, which keeps the barrier to a first test at roughly zero. Run a track. Read the report. Walk away without handing over an email. Paid features sit behind the same interface, so upgrading later doesn't mean learning a new tool.
