How it's made
Source
a hand grabs a steel ammo box. First the lid latch / handle knocks the box wall (a 1–2 ms broadband click), then the loose rounds inside shift and tap each other and the walls.
Body
the thin steel box rings in inharmonic metal-bar modes (≈ 0.8–5 kHz, 40–90 ms) with a short hollow cavity resonance (350–600 Hz) that gives the clack its weight; each round is a small brass cylinder ringing around 3–7 kHz for 10–25 ms.
Envelope
the clack is loudest at t = 0 and dies in ≈ 0.12 s; 2–10 rattle ticks follow within 0.05–0.25 s, spaced irregularly and getting softer and sparser as the rounds settle.
Variation
`rng` jitters tuning (±3 %), tick times and strengths. Size scales the box modes and cavity; Rounds sets the tick count; Looseness sets how long the rattle lasts; Brightness sets the click and tick high-frequency content.
