Body Slam on Mat

How it's made

Source

a body dropping flat onto a padded ring mat. Contact is a broadband slap (2–4 ms of skin and canvas, centred 2–4 kHz) followed by a softer 20–30 ms "thwack" of the canvas skin around 400–900 Hz.

Body

the foam-and-plywood platform acts as a damped membrane/cavity: a falling sine thump (≈ 95 → 48 Hz, 0.3–0.5 s) plus a few damped low modes (≈ 95, 150, 230, 340 Hz, T60 0.1–0.3 s) give the boom.

Envelope

the slap is gone in 15 ms, the boom blooms in 4 ms and dies by 0.5 s; the platform then springs back: two weaker, softer, lower re-contacts at ≈ 0.22 s and ≈ 0.37 s (each ~0.5× the previous), with a slow spring-wobble on the platform modes that is excited by every contact.

Variation

`rng` jitters rebound timing, mode tuning and strength; `weight` scales body size and depth, `padding` low-passes the slap, `spring` sets rebound level and wobble. Presets: heavy slam, light bounce, hard mat, soft crash pad.
