SUS4 Mix Check
Read full descriptionHide full description
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.

Verdict
The clearest difference is in-app purchases: DJ Pyro at none against SUS4 Mix Check's 3. DJ Pyro also leads on iOS requirement (11.0 vs 16.0). SUS4 Mix Check's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
