$ sb get MEBYPXABHM@1 --preset fast -o fast-swoosh.wav

Source: air torn by a small object passing the listener at speed: pink noise for the turbulent body, a second white-noise layer high-passed for the sharp "sh" edge, and a thin resonant whistle from the edge.
Body: band-pass centres rise steeply on approach and fall faster after the pass (Doppler-like brightness curve, 400 Hz -> peak -> 500 Hz); the whistle follows the same curve with a slight pitch offset.
Envelope: short and asymmetric: swell to a sharp peak at about 45 % of the length, then a quicker fall; the level is zero at both ends, so there is no click. Stereo travel crosses the field through the peak.
Variation: length, brightness, edge, whistle and travel; `rng` shifts the peak time and whistle pitch slightly.
