Open-Hand Slap

How it's made

Source

a flat open palm striking skin. Contact is a ~1 ms broadband crack as the air film between hand and cheek or arm is squeezed out, followed by a softer 5–15 ms slap of flesh deformation.

Body

three layers. (1) A crack: noise band-passed at 2.5–6 kHz with a hard high-pass. (2) A flesh slap: noise band-passed around 700–2000 Hz, decaying in ~30 ms. (3) A thump: the underlying limb or torso rings as a damped sine that drops from ~180 Hz to ~90 Hz within 50 ms, plus a weak 250–400 Hz tissue resonance.

Envelope

the crack is gone within 15 ms, the slap within 60 ms, the thump within 120 ms; a faint, short skin-sting ring at 3–5 kHz (decay ~70 ms) trails the strike so it does not end abruptly. Total ≈ 0.25 s.

Variation

`rng` shifts the band centres, thump pitch and layer balance by a few percent per seed, and adds a tiny flam (a second contact 3–7 ms later, as fingers land just after the palm).

Presets differ by hardness and body: a bright comedy crack, a heavy dramatic thump, a light cheek tap and a wet, fleshy hit with a lot of mid slap and little crack.
