How it's made
- Source
- a grenade-sized charge deflagrates in under a millisecond. The overpressure front is a 1-3 ms broadband crack; the expanding gas then pushes a short, low-frequency pressure pulse (thump, 130 -> 42 Hz).
- Body
- the fireball is turbulent noise whose spectrum collapses as it cools (low-pass sweep 5 kHz -> 300 Hz over ~0.5 s); a saturated 900-1600 Hz band gives the mid "crunch" of shredded casing and ground.
- Envelope
- crack ~25 ms, thump ~0.3 s, fireball ~0.45 s, brown-noise rumble tail ~1.1 s. The oneshot is closed by a fade at the target length.
- Debris
- 8-40 small fragments land after the blast, 0.12-1.1 s, with an exponentially thinning rate; each is a 1-4 kHz band-passed noise tick of 4-15 ms with random strength.
- Variation
- `rng` jitters the debris times, tuning and strength; `distance` removes highs and the crack, `debris` sets fragment count, `power` sets the thump and tail weight.
