Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get S9HMJ0Q80Y@1 --preset massive-drag -o heavy-stone-slide.wav
How it's made
Source
a loaded slab drags across stone; pink friction and 12-48 ms grit bursts model asperity contact.
Body
broad, damped contact bands at 85-190 and 240-500 Hz carry mass, below a 0.7-3.8 kHz scrape. Filtered noise, rather than sustained tones, represents the heavily damped slab and supporting floor.
Envelope
load builds in 70 ms, slides for about 1.7 s, then loses speed and settles over 200 ms. Friction bandwidth follows speed; a subdued 110 ms low-frequency stop tremor outlasts the scrape.
Events
18-55 irregular contacts per second overlap; aperiodic 5-12 Hz pressure fluctuations model stick-slip without imposing a motor pitch. Individual grains have 2-5 ms rounded attacks.
Variation
seeded contact timing, grain colour, duration and strength vary independently of the bed. Travel controls time, mass lowers body bands, grit adds coarse contacts, and binding deepens stick-slip.
Presets
rough granite, polished slab, massive slow drag, and a strongly binding uneven stone joint.
Space
dry, centred contact recording; no room response is baked into the asset.
