How it's made
Source
a hinged hardwood stick snapped onto a wooden slate. Each strike is a 0.3–1.5 ms broadband noise burst (hard-on-hard contact) plus a brief band-passed "crack" around 3–5 kHz.
Body
the slate rings in damped inharmonic wood modes (≈ 1 : 2.57 : 4.2 : 6.5, 20–120 ms, fundamental 450–900 Hz for a thin board); a small air cavity under the slate adds a short 180–320 Hz knock.
Envelope
two strikes, the second slightly softer and tuned a few percent off (stick bounce); the whole cut is over in about 0.3 s with a short ring that is damped by the hand holding the board.
Variation
`rng` jitters mode tuning, strike gap and strength; `gap` sets the stick-to-stick spacing, `hardness` the burst length and brightness, `size` the board pitch, `ring` the decay of the modes.
