Finally, someone who tells you the truth about your mix.
Drop your track for a free AI mix analysis. MixJudge's AI tells you the truth about your song with a verdict out of 100 and a concrete action plan to improve your mix and production — plus an AI-mastered version to get you there faster.
A real score, real numbers, and a real action plan — not a black box.
Practical guides on mixing, mastering, and what your technical measurements actually mean for your track.
How does MixJudge work?
Drop your track and MixJudge analyzes it in two steps. First, your browser computes objective technical measurements — loudness (LUFS), true peak, stereo correlation, frequency balance, and more — directly on your device, using the same standards professional mastering tools rely on. Second, those measurements (never the audio file itself) are sent to an AI, which turns them into a plain-English critique: a score out of 100, what's working, what isn't, and a concrete action plan to fix it. Pro users can also generate an AI-mastered version based on that same analysis.
Is MixJudge really free?
Yes — the free tier gives you a full technical and AI analysis once a day, no credit card required. Pro unlocks more analyses per month, AI mastering, and the dashboard.
Do I need to upload my audio file to a server?
No. Every measurement is computed directly in your browser — your audio file itself never leaves your device or gets sent to us.
What audio formats does MixJudge support?
MP3, WAV, FLAC, and M4A.
How accurate is the AI's analysis?
The technical measurements (LUFS, true peak, stereo correlation, etc.) follow the same standards professional tools use (BS.1770). The AI's interpretive judgment (like per-element volume balance without isolated stems) is a heuristic estimate — an informed opinion, not an absolute truth.
What's the difference between Free and Pro?
1 analysis/day vs 100/month, AI mastering (25/month, Pro-exclusive), a dashboard, progress tracking, and report history/comparison. The full breakdown is in the comparison table above.
Can I cancel my Pro subscription anytime?
Yes, directly from "Manage subscription" — no long-term commitment.
Does MixJudge replace a mixing/mastering engineer?
No. It's a fast, honest second opinion — not a certified mastering report, and not a substitute for a human engineer's ears and experience.
What genres does MixJudge support?
Any genre — you tell us the style when you drop your track, and the AI's judgment (like per-element volume balance targets) adjusts to genre conventions.
Is my data private?
Your audio file is never uploaded. We store your account email, your saved reports if you're on Pro, and a usage log to enforce plan limits — see our Privacy Policy for details.
Can I download the AI-mastered version?
Yes, Pro users can generate and download a WAV and MP3 mastered version, up to 25 times a month.
