SUS4 Mix Check: Mix Analyser

Does your mix translate? Find out. A mix analyser measuring LUFS, true peak, frequency balance, loudness range and stereo image. Import from Files or capture live, then compare against a reference track you trust. 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 All analysis runs on-device.
