Mix notes
A more deliberate final mix check
How it works
Load a WAV, MP3, FLAC or AIFF export to inspect the same audio you can play in the workspace. Mixchecker measures integrated loudness, sample peak, estimated true peak, stereo relationships and broad frequency energy. Analysis covers the file locally in your browser. The waveform helps you revisit sections, while the technical checklist brings measurable risks together without pretending to judge the song itself.
Turn findings into decisions
Start with the prioritized release steps rather than trying to make every number look ideal. A peak warning may call for reviewing export level or limiter behavior. A mono warning may send you back to doubled parts, wideners or channel routing. Compare the delivered file with the mix session so that an accidental export change does not become a mastering decision. Keep notes on what you changed and check the new export before replacing the final master.
Read the percentage in context
Release readiness is a transparent technical heuristic, not artistic quality, certification or guaranteed platform acceptance. It combines peak conversion risk, mono compatibility and delivery evidence. Missing or unsuitable evidence stays unscored instead of producing a reassuring partial percentage. A clean master at −0.1 dBTP can score 100%; optional Spotify and Apple headroom recommendations do not deduct general readiness points. Loudness and tonal proportions are not universal pass or fail targets.
Finish with real listening
Listen through the complete track at sensible levels and on equipment you actually use. Check vocal intelligibility, bass definition, transitions and unwanted noises that averages cannot diagnose. Audition Smartphone, Car, Club PA and Cheap Earbuds profiles, or use Studio Flat for neutral playback. Toggle Mono to hear how important parts survive channel combination. These generic approximations complement checks on your own equipment. Mixchecker supports a better final review, not a substitute for your ears.
Frequently asked questions
Is my unreleased track uploaded?
No. Audio, filenames, waveforms and diagnostic results remain on your device. There is no audio upload or remote analysis service.
Does 100% mean the track is ready for every platform?
No. It means the measured technical checklist has no scored issues. Full listening and your distributor’s delivery requirements still matter.
Are speaker simulations available?
Yes. Studio Flat, Smartphone Speaker, Car Audio, Club PA System and Cheap Earbuds are available, alongside an independent Mono control. These are generic approximations, not calibrated device models.
Can I switch tools without loading again?
Yes. Internal tool links retain the loaded track, transport position and completed results for this session. Refreshing the page clears the local session.
