How it's made
- Source
- a leather whip thrown forward. First the thong cuts the air: a band-limited noise swish whose centre frequency and level climb as the tip accelerates. At the end of the throw the tip passes the speed of sound and produces a tiny sonic boom, the crack.
- Crack
- a sub-millisecond broadband click (the shock front) followed by a short, very bright band of noise (4–9 kHz, about 10–25 ms) and a faint ringing of the stiff leather thong (about 2–4 kHz).
- Body
- the handle and the taut thong give a brief low "pop" (350–500 Hz, damped within 30 ms); outdoors there is only a dry air tail, no reverb.
- Envelope
- the swish builds for 0.12–0.25 s, the crack arrives at the swish peak and decays within 0.15 s, then a thin high-frequency tail fades out. The oneshot ends before 0.5 s.
- Variation
- `rng` jitters the ringing tuning and the noise; presets change thong length, stiffness and the amount of lead-in.
