How it works
- 01
Load both tracks
Your mix in slot A, a reference in slot B. WAV or MP3, up to 250 MB and 10 minutes each. Neither leaves your device.
- 02
We level-match them
Both get measured in LUFS and the louder one is turned down to match. Louder always sounds better at first, so this is the step that keeps the comparison honest.
- 03
Flip, look, adjust
Press A or B to switch at the same spot. The spectrum overlay and the list beside it point to where your mix is heavier, thinner, brighter or darker.
Worth knowing
The reference is a guide, not a target.
Pick a reference in your genre with a similar arrangement, or the comparison will point you the wrong way. A song with no 808 will always look light in the sub next to one with an 808. The spectrum is an average of the whole track, so a big drop or a quiet intro shifts it. Matching is by integrated loudness across each full song; if one has a long quiet section, line up the loud parts and trust your ears.
Built in-house, no third-party code. Loudness matching follows ITU-R BS.1770-4.
Need it mixed?
Still can't close the gap? Get it mixed.
If the reference keeps winning, a proper mix gets your vocal, low end and top end where they need to be.
