Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get FXZPWFAE22@1 --preset heavy -o dash-burst.wav
How it's made
Source
a body launching through air. Three layers: a 6 ms broadband push-off transient, a short pitched thump (sine falling 170 -> 70 Hz in ~60 ms) from the foot or body, and turbulent air as pink noise.
Body
the air burst runs through a band-pass (Q ~ 2.6) that sweeps up fast from ~450 Hz to 2-6 kHz in the first 40 % of the length and then relaxes downward as the mover leaves; a faint resonance on the same curve adds a thin whistle edge.
Envelope
attack of 4 ms for the punch, falling to silence over the length (0.25 s); the thump and click die within 60-80 ms so the air carries the tail.
Variation
`rng` shifts the sweep peak time by a few percent and the thump pitch by +-3 %; `brightness` sets the sweep ceiling, `punch` the transient and thump level, `length` the duration, `travel` the pan.
