How it's made
- Source
- heel loading followed by forefoot pressure after 55-115 ms; grains slip and collide underfoot.
- Body
- damped 80-500 Hz soil/sole compression under a dominant 0.8-7 kHz granular crunch, not a ring.
- Layers
- filtered crackle models dense contacts; 12-27 separate 5-25 ms stone taps resolve loose grains. Pink noise supplies friction and a low, non-tonal weight pulse. No reverberation is added.
- Envelope
- 3-7 ms contact attacks, 85-170 ms crunch releases; brightness falls as pressure dissipates. Sparse settling taps decay through 330 ms; the final gate closes by 400 ms, leaving a clean tail.
- Variation
- independent seeded streams vary contact gap, tap timing, strength and stone colour. Grain size shifts bands and density; load controls body; looseness adds settling; scuff adds friction.
- Presets
- fine compact grit, loose coarse gravel, a loaded boot and a short quick step.
