How it's made
- Source
- distant lightning-channel pressure waves, modelled as three independent filtered noise lobes.
- Body
- brown-noise pressure at 35–160 Hz plus a broad pink-noise body; no pitched cavity or crack.
- Distance
- two low-pass stages at 105–240 Hz remove the sharp wavefront; cutoff falls 45% in the tail.
- Envelope
- 0.8–1.5 s rounded attacks, 4.5–8 s decays, with secondary arrivals 0.7–2.1 s later.
- Events
- irregular 14–28 s onset spacing leaves long silent gaps; the first soft arrival begins at 0.4 s.
- Modulation
- independent 0.65 Hz smooth wander gives each lobe gentle, nonperiodic internal grumbling.
- Variation
- seeded length, strength, arrival offsets and narrow pan; presets change distance and spacing.

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