Scenarios

A common scenario: you've dialed in a deep, sub-heavy kick drum that rattles the room on your monitors. The fundamental sits around 42Hz, with a long decay that fills the low end beautifully. You export the track, play it on your phone — and the kick is gone. Not quieter. Gone. What happened? The phone speaker physically cannot reproduce 42Hz. Most phone speakers roll off sharply below 200-300Hz. If your kick's only defining characteristic is its sub-frequency fundamental, there's nothing left for small speakers to reproduce. The kick exists only as inaudible air movement.

The solution isn't to boost 100-250Hz with EQ — that would muddy the entire mix. Instead, add harmonic saturation to the kick drum to generate upper harmonics (100-400Hz) that give small speakers something to latch onto. Alternatively, layer a short, clicky transient sample that provides attack in the 1-3kHz range without affecting the sub weight. A third option: pitch the kick fundamental up to 55-60Hz, which is still deep enough for club systems but has enough harmonic structure to survive phone playback. After these changes, re-running the analysis should bring the LOW band deviation within ±1.5dB of the reference.

You've pushed the master bus limiter hard. The waveform looks like a solid brick. The peak meter barely moves. You upload to Spotify, and — somehow — the track sounds quieter than professionally mastered songs in the same playlist. Worse, it feels flat. The chorus doesn't hit any harder than the verse. There's no emotional contrast. The loudness war promised that louder masters win, but streaming normalization turned that logic on its head. Crushing your dynamics doesn't make you louder on Spotify — it makes you quieter with less impact.

Back off the limiter threshold by 2-3dB. Set the limiter ceiling to -1.0dBFS (not -0.3) to catch inter-sample peaks. Target -10 LUFS Integrated instead of -7 — this gives the limiter room to preserve transients while still hitting competitive loudness for streaming. After these adjustments, re-run the Dynamic Range analysis. The DR value should climb to 6-7, PLR should reach 8-9, and ISP detections should drop to zero. The track will measure quieter on a peak meter but will sound louder and more impactful after platform normalization — because the transients survived.

You've used a stereo widening plugin on your master bus, panned synth layers hard left and right, and applied a mid-side EQ that boosts the side channel across the entire spectrum. In headphones, the mix sounds enormous — like it's happening outside your head. Then you hear it on a club system (mono), a Bluetooth speaker (mono), or a phone (mono), and the mix collapses. The synth pads that sounded cinematic are now thin and phasey. The kick has lost half its weight. The lead vocal is quieter than it was. All that width came at the cost of mono compatibility — and mono is how most people actually hear music outside of headphones.

Insert a mid-side EQ on the master bus and apply a high-pass filter on the side channel at 150Hz with a 12dB/octave slope. This immediately mono-izes the sub-bass where phase issues are most destructive. On the stereo widening plugin, reduce the width below 80Hz to 0% and taper the widening effect above 8kHz to prevent anti-phase buildup in the high frequencies. Replace the mid-side EQ boost on the side channel with targeted boosts above 500Hz only — below 500Hz, keep the side channel subtle. After these changes, re-run Stereo Field. Phase correlation below 150Hz should read +0.7 or above, SUB width should drop below 30%, and mono compatibility should pass.
