How it's made
- Source
- a focal-plane or leaf shutter in a small camera. Two mechanical events: the blades/curtain opening and, a few tens of ms later, closing. Each is a 1–2 ms broadband contact (metal hitting a stop).
- Body
- the shutter assembly rings in damped steel modes (≈ 2.4–6.5 kHz, ratio ≈ 1 : 1.9 : 3.1, 8–25 ms); the camera body adds a short hollow knock (500–1100 Hz, 10–25 ms). The closing click is slightly lower and softer than the opening one, as the curtain is slowed by its damper.
- Envelope
- attack under 0.5 ms; each click is gone in about 40 ms. Between the clicks a faint band-limited noise (curtain travel, 3–7 kHz) fades in and out over the exposure gap.
- Layers
- contact noise, metal modes, body knock, curtain travel noise; all dry and centred.
- Variation
- `rng` mistunes the modes by ±3 % and varies click strength; `gap` sets the exposure time, `size` scales mode frequencies (compact vs. reflex), `brightness` the contact noise and mode balance.
