Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get ZZ4SNP9D8C@1 --preset shatter -o car-crash-crunch.wav
How it's made
Source
two vehicles collide. The impact is a heavy, short transfer of momentum, followed by the body panels buckling and tearing in a burst of irregular metal events, and finally loose glass falling.
Body
(1) a low thump: a sine dropping from ~95 Hz to ~42 Hz plus low-passed brown noise, the chassis absorbing the shock; (2) a mid "slam" of the sheet-metal panels: damped inharmonic modes; (3) crumple: 10-30 small metallic events (band-passed noise snaps into short metal-bar modes), densest in the first 0.4 s and thinning out as the metal settles; (4) glass: sparse small bright glass-mode ticks from 0.12 s to the end, each tiny and quickly damped, getting softer and rarer.
Envelope
the thump peaks within 3 ms and decays over ~0.5 s; the crunch runs ~1 s with falling strengths; the glass tinkle tails off by ~2.2 s. Everything is dry, no room.
Variation
`rng` places and tunes every crumple and glass event, so each seed is a different crash.
