EMP Blast

How it's made

Source

a discharge of stored energy. A sub-bass electric thump (sine falling 85 → 34 Hz in ~0.4 s, lightly saturated) carries the pulse; a 4 ms broadband snap marks the arc; the electronics then lose power.

Body

the crackle burst is sparse unipolar sparks band-passed at 2–6 kHz, dense for the first 0.3 s and thinning out as the circuits die. The power whine is a detuned saw pair plus a 2nd partial, low-passed, falling from 2.6 kHz to ~110 Hz while a mains-like buzz at 100 Hz fades with it.

Envelope

thump peak at 0, crackle tail ≈ 0.9 s, whine decays exponentially over ~1.5 s with a small flutter that grows as the supply sags; everything is gone by `length`.

Variation

`rng` jitters spark timing, whine detune and flutter phase; `power` sets the thump depth and level, `crackle` the spark density and `whine` the pitch start and length of the fall.

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