Why AI Mastering Tools Don't Tell You What's Wrong with Your Mix

AI mastering tools process your audio and give you a finished master. But none of them tell you what's wrong with your mix.

The Problem

When you upload to LANDR, you get a mastered track back. You don't get: "Your low-mids are 4 dB too loud at 350 Hz" or "Your crest factor is 5 dB — you're over-compressed." You just get a louder version of your mix.

The Pre-Mastering Gap

Every professional workflow has a pre-mastering check. The mixer sends the track to the mastering engineer, who sends back notes. This feedback loop doesn't exist in the AI mastering world — until now.

What MixDiagnose Does

MixDiagnose doesn't master your track. It diagnoses it. Upload a track and in 30 seconds get:

• Frequency balance across 5 bands
• Loudness — LUFS, true peak, streaming platform comparisons
• Dynamics — crest factor, over-compression detection
• Stereo width — mono compatibility, phase issues

Plus a Mix Score (0-100) and specific fix recommendations.

The Workflow

1. Mix your track (any DAW)
2. Upload to MixDiagnose — get your score and fixes (30 seconds, free)
3. Fix the issues in your mix
4. Re-upload to verify improvement
5. Send to mastering — LANDR, eMastered, or a human engineer

The result: better mix in, better master out.
