How it's made

Source

a cinematic hit stacks three events fired together: a heavy low-frequency drop (sub), a struck metal object and a saturated broadband crack. The crack is a 2–6 ms noise burst driven into a tanh stage.

Body

the sub is a sine that falls from ≈ 100 Hz to ≈ 38 Hz in 0.35 s (pitch drop of a big drum or detonation). The metal layer is a modal bank (metal-bar, large size, 2–3 s T60) whose upper modes decay faster; it is darkened with a low-pass so it reads as a heavy plate, not a bell. The tail is brown noise through a low-pass that closes from ≈ 900 Hz to ≈ 120 Hz, plus a 55 Hz room-like rumble.

Envelope

crack ≈ 0.12 s, sub ≈ 1.6 s, metal ≈ 2.6 s, rumble ≈ 1.5 s; the whole hit fades to silence at the end of the render. A 1 ms attack on every layer keeps the transient free of clicks.

Layers

a shared saturator glues the layers so the crack and sub share one soft-clipped peak; the dry (unsaturated) tail is added after it to keep the tail clean and dark.

Variation

`rng` detunes the metal modes by a few percent and seeds the two decorrelated tail noises; macros set sub weight, metal amount, darkness, tail length and saturation drive.
