Frequently Asked Questions

What is a Mix Score?

A Mix Score is a 0-100 rating based on 12 objective metrics: 6 frequency bands, LUFS integrated, true peak, crest factor, and stereo width. Each metric is scored as good (100), warn (60), or bad (25). The final score is the average minus 8 points per Critical issue.

What's a good Mix Score?

85+ = Grade A (release-ready). 70-84 = Grade B (almost there). 55-69 = Grade C (needs work). Below 55 = major issues. See how hit songs score for reference.

Is it really free?

Yes — 3 free analyses per IP, no signup. Share your report card for 3 more. Unlimited analysis starts at $19/mo.

Does it work with any genre?

Yes. The scoring is universal — no genre selection needed. Some genres (trap, metal) intentionally have lower crest factors, which will score lower but may be creatively appropriate.

Can I use it from the terminal?

Yes — the REST API takes a file and returns JSON: curl -s -X POST https://mixdiagnose.com/api/analyze -F "file=@my-mix.wav". See API docs.
