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.
