How it's made
- Source
- a riffle shuffle. Two half-decks are bent and released so single cards flick off the thumbs and interleave. Each card edge is a tiny paper "tick": a 1–3 ms noise transient with most energy at 2–8 kHz.
- Body
- every card also slaps the stack below, a soft papery thwap (bandpassed noise around 700–1800 Hz, 5–14 ms decay) plus a faint low card-stock thump (150–260 Hz). A continuous airy rustle (bandpassed noise at 1.5–6 kHz) glues the individual flaps into a dense flutter.
- Envelope
- the flap rate accelerates (intervals shrink about 5x over the run) while levels swell, as the thumbs release faster; the rustle follows the same swell and the whole flutter drops away after the last card.
- Finale
- the bent halves are pressed into a bridge and snap flat: a louder, longer slap (2–25 ms), a low body thump near 120 Hz and a short papery decay.
- Variation
- every card draws its own timing jitter, level, brightness, pan and thwap pitch from its rng.
