How it's made
- Source
- a pressurised actuator vents air (turbulent pink noise, 0.9–5 kHz) while a small electric motor drives the door leaf (a saw-rich tone with a 2nd and 3rd partial, 140–380 Hz fundamental).
- Body
- the vent hiss is shaped by a band-pass (Q ≈ 0.9) whose centre falls as the pressure drops; the motor passes through a low-pass at 6x its pitch and a gentle track resonance near 900 Hz.
- Envelope
- a 6 ms latch tick, then a 0.04 s hiss burst that decays over the travel; the whir rises in pitch and level for the first 45 % of the travel and winds down; a second soft puff and a 55–95 Hz damped thud mark the leaf hitting its rubber stop at about 78 % of the length.
- Variation
- `rng` shifts the stop time by a few percent and detunes the motor; `length` stretches the travel, `whir` and `thud` balance the layers, `air` sets hiss brightness.
