How it's made
- Source
- nucleate boiling excites 55-900 Hz water turbulence and 8-18 mm bubble chirps; steam escaping through a lid aperture supplies a 900-6500 Hz breathy jet that brightens with rising pressure.
- Body
- the water-loaded vessel colours the rumble around 190 and 470 Hz; an edge-tone locks to the whistle cavity at 1450-2800 Hz, with a weak second harmonic and a noisy resonant skirt (Q 9).
- Envelope
- boiling grows over 0-2.5 s; breath precedes tonal lock by 0.5 s. The whistle rises by 18 percent as flow builds, sustains to 4.5 s, then pressure and all layers release smoothly by 4.95 s.
- Modulation
- irregular pressure drift and 4.7 Hz flutter move pitch by 0.1-1.3 percent; low-rate pressure pulses also modulate the jet and whistle together, strongest in the sputtering preset.
- Variation
- seeded bubble radii, strength and timing, pressure drift and tuning differ between renders. Presets change cavity pitch, lock-on time, boiling weight and flow stability; the sound stays dry and mono.
