We ran a real indie-pop track through MixDiagnose. It found 7 specific issues — each with a severity grade, an exact recommendation, and a one-click fix. Then we re-analyzed the fixed mix.
Same song. Same ear. Just MixDiagnose doing the diagnosis. Here's exactly what changed.
Each card shows the problem MixDiagnose detected, its recommendation, and the fix the producer applied.
MixDiagnose flagged a 6 dB buildup centered at 300 Hz across the full mix — the classic "mud" zone. Vocals lost presence and the kick/bass relationship got smeared.
A sharp 4 dB peak at 4 kHz made cymbals and the vocal's "ess" bite through fatiguingly. MixDiagnose measured energy 2.3× the ideal reference in the 3–5 kHz band.
The mix measured -8 LUFS integrated — 6 dB hotter than the -14 LUFS streaming target. Every platform would apply aggressive normalization and the dynamics would get crushed on playback.
Crest factor measured 4 dB — meaning the peak was only 4 dB above the RMS. A healthy mix sits around 8–12 dB. The track sounded flat and lifeless, with the snare and transients squashed.
Stereo width meter showed 180° correlation in the low end and an over-wide mid band. Summing to mono caused a 4.2 dB drop — elements vanished, especially the wide synth pad and centered vocal.
True peak meter read +0.3 dBTP — above 0 dBFS, meaning inter-sample peaks were clipping. This causes distortion on conversion to lossy formats (Spotify, Apple Music) and playback degradation.
The 20–80 Hz band measured +6 dB over the reference curve. The bass and sub were overpowering everything, especially on small speakers where it translated as a muddy rumble and a one-note low end.
Same analysis engine, same reference curves. The only difference is the fixes MixDiagnose recommended were applied.
