How it's made
Source
a padded car door compresses its rubber seal; 3 ms rise, 28 ms low-passed contact noise. A preceding 35 ms air displacement narrows from 1.8 kHz to 450 Hz as the opening closes.
Body
damped sheet and trim modes at 83, 137, 219, 346, 571 and 913 Hz have 90-360 ms T60. A broad 100-155 Hz cabin pressure resonance adds a dull pop without a synthetic pitch drop.
Latch
the rotary catch seats 14-26 ms after contact, then a quieter pawl follows 12 ms later; 1.2-3.3 kHz filtered noise and short inharmonic modes form a click, never a ringing clang.
Envelope
air moves immediately; contact peaks near 40 ms. High modes disappear before the low panel settles. A 620-700 ms finishing fade leaves 100 ms of silence within the 0.8 s maximum.
Variation
seeded tuning varies by 1.5 percent and latch timing by 2 ms. Mass lowers the modes; seal softens contact, pressure controls the pop and damping shortens the panel vibration.
Presets
padded sedan, light compact, heavy utility door and close cabin perspective vary mass, seal absorption, latch prominence and pressure balance. Dry mono foley, without room reverb.
