How it's made
- Source
- a padded leather glove hits a heavy canvas bag. The contact is a very short broadband slap (2–6 ms) from leather and air squeezed out of the padding; a softer glove low-passes it and lengthens it.
- Body
- the filled bag answers with a low thump, a damped sine that falls from about 130 Hz to 55 Hz over ~0.1 s as the fill compresses, plus a dull cavity resonance of the canvas shell around 200–300 Hz.
- Chain
- the hanging chain and snap hooks shake 6–50 ms after the hit. A few small, high, strongly damped metallic modes (2.5–7 kHz) at staggered start times make a short jingle, much quieter than the hit.
- Envelope
- slap and chain are over in under 0.15 s; the thump carries the tail to about 0.3 s, then a closing envelope reaches silence by 0.35 s.
- Variation
- `rng` jitters the thump pitch, slap colour, and chain tuning per seed.
