How it's made
- Source
- a toxic gas cloud billowing out of a cauldron-like vent. Three layers: a murky low body (brown noise plus two slightly detuned low sines that beat slowly), a wet hiss (pink noise high in the spectrum, the gas escaping) and bubbling (small air bubbles popping at the surface, Minnaert pitch f0 = 3.26 / r).
- Body
- the murk is low-passed at 150-450 Hz and opens as the cloud expands; the sines sit at about 62 Hz and a close detune, so the beating reads as a slow, uneasy pulse. The hiss is band-passed around 3-6 kHz with a centre that drifts upward as the cloud thins out; bubbles are 2-9 mm, bigger ones lower and rarer.
- Envelope
- slow spread, not an attack: the level swells over roughly 40 % of the length, holds, and dissolves in a long fade. Bubble density follows the same hump: sparse, busy at the peak, sparse again.
- Space
- width grows from nearly mono at the vent to wide as the cloud spreads; the hiss uses decorrelated noise per channel, bubbles are panned at random.
- Variation
- `rng` varies the bubble radii, times and pans, and the detune of the low pair.
