How it's made
- Source
- heavy steel links slide over stone; pink friction at 85-1800 Hz under 12-45 ms grit bursts.
- Body
- link collisions excite inharmonic modes at roughly 420, 727, 1184, 1877 and 2982 Hz, scaled by link mass and detuned per contact; T60 is 65-330 ms because adjacent links damp the steel.
- Layers
- a low 90-420 Hz contact grind, moving midrange abrasion, and clustered metal clinks. Stone contacts add a broad, heavily damped 220-900 Hz knock rather than a sub-bass boom.
- Envelope
- continuous dragging with slow random pull pressure (0.7 targets/s) and stick-slip flutter (9 targets/s); pressure jointly moves scrape cutoff and 5-17 collisions/s. A 6 s loop uses the engine seam crossfade; individual rings fade before their voice allocation ends.
- Variation
- seeded contact strength, tuning +/-12%, pan and a 17-43 ms secondary link bounce. Mass lowers modes, roughness raises abrasion, speed changes event density, and slack opens the ring.
- Presets
- massive dragging, gritty flagstones, smooth slabs, and loose rattling links; dry close foley.
