Tool

Online Mix Checker

Upload a bounce from any machine - no plugin install. Get LUFS, stereo, phase, and frequency feedback in about a minute, plus a ranked fix list.

MixMaster Pro is the living Mix Intelligence platform for producers. Analyses stay in your Mix Library, revisions compare on the same mix, references save to your account, and Maya on Studio coaches from your bound report - connected workflows instead of one-time uploads.

Useful when you are on a laptop without your main DAW, sending a quick check to a collaborator, or validating a bounce before a mastering session.

How to check your mix

Export stereo WAV 24-bit (MP3 works for quick checks).
Formats: WAV, AIFF, FLAC, MP3 up to 100 MB.
Free tier: tracks up to 5 minutes.
Typical wait: 30-60 seconds.

What you get back

LUFS, true peak, RMS, loudness range.
Frequency balance and problem bands.
Stereo width and phase warnings.
Section-level energy (verse vs chorus lift).
Mix score and prioritized action items.

Key takeaways

Browser-based - no install.
More than LUFS-only meters.
Re-upload to track progress across revisions.
