Prompt
A 0.5-second synthesised DSLR shutter, crisp and mechanical with no musical tone. On frame 0 the mirror flips up with a hard clack: a sharp grit transient over damped, inharmonic metal-and-polymer body modes, a small mono thud and a tiny mirror bounce 6 ms later. The focal-plane curtains then run as a short whirr: two quick, grainy swipes of band-passed noise, chopped by an irregular gear ratchet whose filter sweeps upward as each curtain crosses the frame. At 125 ms the mirror drops back with a second clack, a little lower and heavier than the first. A tiny return spring then rattles: six to seven quick metallic ticks that bounce closer together and quieter, each ringing for only a few milliseconds so no pitch forms. A small, close room keeps it tight. Everything has settled by about 0.33 s, and the last 60 ms fade to silence.

- Frame 0: shutter
Mirror-up clack on frame 0 (band-passed grit over damped inharmonic body modes 1.2/2.7/4.3/6.9 kHz, 4x-oversampled tanh to round the coincident peak, mirror bounce at +6 ms, mono 175 Hz thud), two grainy curtain swipes (SVF band-pass sweeping up, chopped by a jittered ~1.1-1.6 kHz gear ratchet so no pitch forms) at 24 and 68 ms, a lower mirror-down clack at 125 ms, then a 7-tick return-spring rattle bouncing closer and quieter. Close 0.14 s room, 90 Hz high-pass, 11 kHz low-pass, side HP 300 Hz; ~2.4 dB peak limiting on the first clack only. 5 ms RMS arc: -9 clack, -15 curtain 1, -14 curtain 2, -10 mirror-down, -21..-34 spring ticks, settled below -57 by 0.25 s.
