How it's made
Source
lever spindle and latch cam rubbing during downstroke and spring-driven return. Two rounded 0.7 ms attacks excite 5-9 ms contact bursts at 0.065 s and 0.31-0.40 s.
Body
gripped metal lever modes at 740, 1265, 2190 and 3540 Hz decay in 45-115 ms; the mounting plate contributes damped 235 and 410 Hz modes, without a door-slam boom.
Envelope
downstroke friction swells over 0.18 s, pauses, then a quicker 0.09 s return brightens into the second stop. The spring unloads with a falling 1.8-0.9 kHz noise band.
Layers
low cam clack, brighter latch clicks, moving 0.6-5 kHz friction and quiet spring rasp; all are dry and centred for close-miked foley. The final ring fades before 0.56 s.
Variation
seeded mode tuning varies by 1.5 percent, return timing by 3 ms and grain by seed. Mass lowers modes, friction raises roughness, damping softens contacts, return time sets pace.
Presets
firm steel office lever, quiet lubricated lever, heavy brass lever and worn dry spindle.
