Source: a body rising through water and breaking the surface. Below the surface: turbulent rumble (brown noise) and trapped air bubbles of 2–8 mm ringing at 0.4–1.6 kHz (Minnaert), their rate rising on the way up.
Body: water is a low-pass medium, so everything below the surface is muffled (cutoff ≈ 250–700 Hz). At the break the medium changes to air and the low-pass opens within ≈ 0.4 s from the muffled cutoff to ≈ 9 kHz.
Splash: a 3–6 ms broadband noise crack, a bright band-passed spray (3–6 kHz, ≈ 0.25 s) and a slower sheeting wash of water running off (pink noise through the opening filter, ≈ 0.6 s).
Envelope: ≈ 0.6 s of submerged build-up, an instant bright break, then dripping and a faint open-air bed that decay to silence; small bright droplet bubbles (0.8–2.5 mm, 1.3–4 kHz) fall in sparse, slowing events.
Variation: `rng` jitters bubble sizes, timing, strengths and the break time by a few percent; presets change depth (muffling), splash size, droplet count and length.

Parameters
Parameter	Range	Default	Unit	Controls
length	1 – 2.4	1.5	s	Length
depth	0 – 1	0.5	—	Higher values muffle the submerged part more
splash	0 – 1	0.6	—	Splash
bubbles	2 – 14	7	—	Bubbles
droplets	2 – 14	7	—	Droplets
breakAt	0 – 1	0.4	—	Where in the length the surface is broken
seed	int	1	—	Variation, reproducible

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
