How it's made
- Source
- pressurized steam through a weighted vent; white-noise turbulence spans 700-8500 Hz, with a softer 180-1400 Hz pink-noise throat. Valve lift modulates both at 9-29 cycles per second.
- Body
- an unstable jet edge-tone at 1550-3200 Hz has a weak second partial and a Q 12 noise skirt. The loose weight strikes its seat, exciting damped 920, 2370 and 4180 Hz modes for 25-65 ms.
- Envelope
- steam rises in 160 ms, whistle locks by 320 ms, and the release holds until 1.9 s. Falling pressure lowers pitch and brightness; the tone dies before the last hiss at 2.95 s.
- Modulation
- the same valve cycle gates flow and pitch; seeded pressure wander adds 0.7 percent pitch instability. Contact strengths and tuning vary, with no room reverberation or stereo spread.
- Variation
- presets change vent pitch, weight cycling, contact level and steam pressure: regular release, a slow heavy rocker, a fine quiet valve, and a strong hiss-dominant pressure discharge.
