How it's made
Source
a massive steel leaf swings on loaded hinges for 0.7 s, then seats against its frame. Filtered friction noise rises and darkens; a 4 ms contact excites the door, not an explosive click.
Body
thick plate modes at 53, 79, 116, 173, 247, 361, 529 and 811 Hz are inharmonic. Low modes decay over 2.5-3.4 s T60; upper modes over 0.3-1.2 s. Split modes give slow beating.
Mass
a broad 65-140 Hz compression thump lasts 180 ms beneath the resonant steel body.
Bolts
3-5 heavy bolts slide for 85 ms then strike their sockets at 0.18-0.31 s intervals. Each has a short 140-900 Hz body, a muted 1.7 kHz contact and a small seating rebound 35 ms later.
Envelope
swing, frame impact, sequential locking, then a low ring; highs decay first. A 220 ms fade ends the dry mechanical action near 4 s; no room reverb is baked in.
Variation
seeded tuning shifts by 0.8 percent, bolt timing by 9 ms and strength by 10 percent. Presets change plate mass, damping, swing speed and bolt count, from serviced to old treasury doors.
