How it's made

Source
a charged plasma shot in three stages. A capacitor whine (two detuned saws, 120 Hz rising to ≈ 1.1 kHz) swells for the charge time; the discharge is a 3 ms noise crack plus a sub-bass thump; a hot ionised column then bubbles and relaxes into a descending tail.
Body
the thump is a sine falling 125 → 36 Hz with a saturated saw (140 → 72 Hz) adding weight at 70–250 Hz; the crack is white noise through a band-pass sweeping 7 kHz → 700 Hz. The bubbling cavity is noise through a Q ≈ 9 band-pass at 650 → 170 Hz whose centre is wobbled by a 14 Hz LFO, plus 2–9 mm bubbles (≈ 0.35–1.4 kHz).
Envelope
charge swells for 0.1–0.6 s and is cut by the discharge; the blast peaks in 3 ms, falls to a third in 30 % of the tail and is silent at the end; the bubble rate and pitch both fall as the plasma cools.
Variation
`rng` jitters charge tuning, bubble sizes and timing; `power` sets sub weight and saturation, `bubbling` the resonance and bubble level, `brightness` the whine and crack, `tail` the relaxation time.
