Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get 70NKRGN5F2@1 --preset papery-scuff -o footstep-on-dry-leaves.wav
How it's made
Source
a shoe compresses dry autumn leaves, first heel then forefoot 65-115 ms later. Filtered micro-fractures and discrete 2-12 ms vein snaps model brittle leaf failure.
Body
a quiet 90-430 Hz ground contact supports broad, damped 0.8-7 kHz leaf noise; no pitched cavity or reverb. The high-frequency edge darkens as fragments stop moving.
Envelope
4-8 ms contact rise, two overlapping pressure bursts, rapid fracture decay; papery sliding spreads outward after the toe and settles by 0.49 s, leaving a clean tail.
Layers
1100-3300 micro-cracks/s during pressure, 24-52 irregular vein fractures, and independent left/right friction beds; rounded noise thumps remain beneath the leaves.
Variation
seeded timing, strength, bandwidth and pan vary per fracture and step. Weight changes contact body, depth changes fracture count, and drag changes the spreading tail.
Presets
light shallow tread, heavy deep litter, fast brittle step and broad papery scuff.
