Source: an electronic sub-bass drop. A sine oscillator whose pitch dives exponentially from a high start (about 110 Hz) down to a sub floor (about 32 Hz), the way a kick or a "bass drop" synth is built.
Body: three layers. (1) The fundamental sine carries the weight below 60 Hz. (2) A second sine one octave up with the same dive, kept quiet, gives the low end an audible shape on small speakers. (3) A short, low-passed noise thump marks the start of the drop. Light tanh saturation adds a few low harmonics without harshness.
Envelope: a 4 ms fade-in avoids a click, the level holds briefly, then decays smoothly and almost exponentially. The pitch dive is fastest in the first third and settles on the floor.
Variation: length, floor pitch, dive depth, weight (saturation) and thump amount; `rng` nudges the start pitch by a few percent.

Parameters
Parameter	Range	Default	Unit	Controls
length	0.8 – 4	2	s	Length
floor	24 – 55	32	Hz	Floor pitch
dive	0 – 1	0.6	—	How far above the floor the pitch starts
weight	0 – 1	0.35	—	Weight
thump	0 – 1	0.4	—	Thump
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.
