Rubble Settle

How it's made

Source

loose rubble loses support after a collapse; pink friction bursts model short slides, while filtered granular impulses model small pebbles cascading through gaps, not a continuous hiss.

Body

stone contacts excite inharmonic modes at roughly 180-1800 Hz with 25-130 ms damping. Larger blocks add broad 70-320 Hz contact energy; small gravel occupies 0.8-6 kHz.

Envelope

slides rise in 15-45 ms and stop in 0.25-0.9 s; their cutoff falls as motion slows. Gravel packets last 0.15-0.65 s. Rounded 3-8 ms thud attacks prevent impulse discontinuities.

Events

independent irregular slide, trickle and thud schedules leave real gaps. Rates and strength decline over the first 15 s, approaching a sparse residual activity for extended texture renders.

Variation

seeded timing, grain size, damping, strength and pan vary per event. Activity changes spacing, mass shifts contact bands downward, gravel changes packet detail, settling controls thinning.

Presets

fine gravel trickles, weighty block shifts, a loose scree pile, and the last isolated stones.

Space

dry stereo contact field with modest random positions; no room or collapse blast is included.
