A 1.2-second cinematic pass-by whoosh, 57,600 samples, 30 fps, closest approach exactly on frame 18 (0.6 s). Pink noise through two decorrelated band-passes whose centre rises from 300 Hz to 3.5 kHz into the pass and falls to 900 Hz after it; a faint airy tonal partial (~700 Hz) carries a true Doppler bend (+3 semitones approaching, -3 receding); the pan moves left to right with a 0.4 ms interaural delay at the pass; a light comb flange (notches sweeping up) adds motion; distance is modelled as a low-pass that opens to 9 kHz at the pass and closes after. Smooth fade-in from silence, ~0.4 s tail to true silence. No low end below 80 Hz. Take angle 1 (faithful): implement the brief exactly as written.

- Frame 18: pass (closest approach)
Two decorrelated pink-noise band-passes sweep ~300 Hz → 3.5 kHz into frame 18 and fall to ~900 Hz after; a faint 700 Hz partial carries a physical Doppler bend (+3.3 / −2.7 st), with a distance low-pass opening to 9 kHz at the pass. Hard left-to-right pan with an interaural delay of 0.4 ms × sin(azimuth), a light upward comb flange, loudest 20 ms at 605 ms; silent by ~0.97 s, nothing below 80 Hz. Take 1 of 3 (faithful), picked as the clearest, most complete pass-by.
