$ sb get 5TX1EPAA2Q@1 --preset swipe -o soft-whoosh.wav

Source: air displaced by a soft, slow-moving mass: pink noise is the turbulence; a second, high-passed layer at 3 kHz and above supplies the airy breath.
Body: two band-passes (Q ≈ 0.7, broad and smooth, no ringing): a body band sweeping 350 → 1800 → 500 Hz and an air band sweeping 1.5 → 5 → 2 kHz; a gentle low-pass at 9 kHz keeps it free of hiss.
Envelope: slow swell to a peak at about 50 % of the length (raised-cosine-like curve, ≈ 0.4 s attack) and a longer fade to silence; both ends start and end at exactly zero, so there are no clicks.
Variation: length, brightness, softness (air versus body balance) and travel across the stereo field; `rng` shifts the peak time by a few percent.
