Drop your rough and your finished mix. MIXProof lines them up to the sample, finds your best moments, and turns them into a before and after you can post: a vertical reel, a square post, a portfolio card or the audio.
Drop your before and your after. MIXProof level-matches them so loudness can't fake the win, finds your strongest section, and builds a synced before/after you can share anywhere. Free.
MIXProof runs entirely inside your web browser. Your files open on your machine, every number and every export is made on your machine, and nothing is sent anywhere. Unreleased songs and client work are safe here.
Your audio is never sent to us or to any server. It plays and renders right here, on your computer.
No AI listens to your music and nothing is trained on it. The alignment and the numbers are plain audio math, the same kind your meters do.
We never store your files, because we never get them. Your own browser holds your session so a refresh doesn’t lose your work. Start over clears it.
Don’t take our word for it. Once this page loads, turn off your Wi‑Fi and drop your mixes. It still works, start to finish.
The only things that ever reach us: the name and email you choose to give for your downloads, and anonymous counts of which buttons get clicked. Never your files, your song titles or your audio.
The rough before the mix, and the mix exactly as printed, locked together to the sample. The rough plays, then the mix lands on the downbeat: exactly how MIXProof builds yours. Try a shorter or longer moment, take the switch yourself, or tap anywhere on the song to hear it there.
Every number here comes from the full-length 24-bit bounces, rough against mix. The tone chart is normalized for level, so it shows what changed in the balance, not just the volume. No presets, no adjectives, no guessing.
The Mac app that gets a session ready to mix.
Not for you if your problem is the mix itself. This fixes prep, not decisions.

Step into the Control Room
The mix you just heard came off this desk. Not for you if the recording is not there yet. I will tell you straight.
Yes. No account, no trial, no card. You give a name and email when you download your proof, and your videos and cards carry a small “Made with MIXProof” credit.
Yes. Your files never leave your computer. MIXProof opens, measures and exports them inside your browser, and nothing is uploaded. How it works
No. Nothing listens to your music but you. Lining the mixes up, picking the moments and the numbers are all plain audio math running on your computer, and nothing is trained on your songs.
WAV, AIFF, MP3 or FLAC, straight out of your session. If one bounce starts a little earlier than the other, MIXProof finds the offset and lines them up to the sample.
No. Your mix plays and exports exactly as you printed it: no limiter, no EQ, no loudness tricks. Match loudness only turns the mix down while you listen, so you can judge it fairly.
Yes. The example plays anywhere, and the whole tool works on iPhone and iPad when your mixes are on it. If they live on your studio computer, tap Send to my computer and pick it up there.
