SUS4 Mix Check: Mix Analyzer

See whether your mix is too loud for streaming before you send it. Measure LUFS, true peak and loudness range, compare the numbers with a reference track, and get a plain-English report. Fully on-device: no cloud, no account. Import a file or capture live input. Mix Check grades it against a streaming service's loudness target and a genre profile, then lists what is off: 2.2 LU too loud, true peak within the ceiling, the low end 1.2 dB darker than the reference. • Integrated, short-term and momentary LUFS (BS.1770-4), true peak and loudness range • Targets for the main streaming services and EBU R128 • Your mix next to a reference: loudness, dynamics, stereo correlation and frequency balance • A plain-English report of what to change • Session history: pin two versions of your mix and overlay their spectrum For home-studio producers, mixing engineers and bands who master their releases at home. Mix Check measures; it does not play audio back. Pro, or SUS4 All-Access across the whole range, removes the daily limit on analyses. Made in the UK by working musicians.
