Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.

How it's made
Source
stressed trunk fibres slip in irregular 8-90 ms bursts, accelerating into a final fracture. Filtered noise excites short wood modes; a pulsed, moving 180-1100 Hz friction band adds creak.
Body
trunk modes at 72, 119, 207 and 341 Hz scale inversely with size, with 0.12-0.48 s damping. Ground contact combines a 25 ms soft excitation, 45-220 Hz soil compression and broken wood.
Envelope
strain begins immediately; crown rush rises from 0.6 s to impact at 2.5-3.7 s. Branch contacts precede the main thud; secondary contacts follow it by 90-380 ms.
Layers
decorrelated 450-7600 Hz leaf turbulence brightens during acceleration, then collapses. Small twig and leaf events scatter for 1.9 s after impact; all layers fade by 6.1 s.
Variation
seeded timing, force, wood tuning and pan; size sets mass, foliage sets crown density, brittleness sets fracture brightness, soil sets contact hardness, fall time sets acceleration.
Presets
broadleaf crown, brittle deadwood, light sapling and a massive trunk landing on soft soil.
