Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get T76M5Y6D13@1 --preset heavy-char -o burning-log-collapse.wav
How it's made
Source
a charred log fractures under its own weight; 3-12 ms filtered noise excites damped wood.
Body
hollow 110-230 Hz cavity and inharmonic wood modes, 45-180 ms decays; no metallic ring.
Events
a leading fracture, then irregular contacts at 0.08-0.85 s; fine fibre snaps thin by 1.7 s.
Layers
displaced embers emit 2-8 ms crackles and a 1-7 kHz spark fizz, strongest after impact.
Envelope
air-fed combustion swells at 0.2-0.6 s, then darkens and settles to silence by 2.4 s.
Variation
seeded contact timing, mode tuning, burst duration and narrow pan prevent repeated hits.
Controls
log size lowers the body; fragmentation adds contacts; sparks and draft set fire balance. Presets cover brittle kindling, a hollow hearth log, heavy char and a spark-rich collapse.
