SUS4 Mix Check

Does your mix translate? Find out. You have been in the session for four hours and you have lost perspective. SUS4 Mix Check gives you an objective read: A/B your mix against a professional reference track, check integrated LUFS against streaming platform targets, and see the frequency spectrum of both tracks overlaid so gaps and buildups are visible immediately. The plain-English report translates the technical data into actionable language — not a raw frequency chart that requires interpretation, but a clear note that says what needs attention and where. Useful for the final check before you send a mix to a client, and useful mid-session when you need a reset. • A/B comparison: your mix against any reference track • Integrated LUFS measurement against streaming platform targets • Spectrum overlay: your mix and the reference on the same display • Plain-English report — specific, actionable, no jargon required • Genre reference presets for common target levels • Unlock once: unlimited analyses, genre references, spectrum history, and full reports All analysis runs on-device.
