How it's made
- Source
- a small solid pebble hits bare rock; a 1.4-3.6 ms band-limited noise contact makes the click.
- Body
- twelve irregular solid modes span about 0.8-8 kHz, with 18-65 ms T60; upper modes die first. A broad 350-950 Hz surface response adds weight without a hollow cavity or a pitched metallic ring.
- Envelope
- 2-6 contacts lose amplitude geometrically. Flight intervals shrink by 0.62 after each rebound; weaker impacts have less high-frequency energy and shorter body decays.
- Layers
- a quiet 9-18 ms filtered grit burst follows each contact as the rough surfaces slip. The response is dry and centred, with sub-bass removed and a silent release before the render ends.
- Variation
- seeded contact noise, mode tuning (+/- 3 percent), timing (+/- 4 percent), and impact level. Size changes mode frequencies and weight; hardness changes contact bandwidth and damping.
- Presets
- small sharp chips, round muted pebbles, heavier stones, and low-height skittering rebounds.
