Dice Roll

How it's made

Source

hard plastic dice tumbling on a table. Every contact is a 0.3–1 ms noise tick from a corner or face hitting the surface; harder bounces are louder and brighter.

Body

a die is a small, lightly damped plastic cube: a few inharmonic modes at 2.5–6 kHz that ring 8–30 ms (the "tok"). The table adds a low, damped thump (120–300 Hz for wood, shorter and duller for felt), and the rolling faces add a faint band-passed rumble that fades as the die stops.

Envelope

the bounces follow a bouncing-ball law. Each gap is a fixed fraction of the last one and each hit is softer, so the clicks speed up and fade. Once the gaps drop below ~25 ms the die rocks and settles in a handful of tiny, quiet ticks (the rattle).

Variation

`rng` jitters the timing, level, pan and mode tuning of every contact and gives each die its own pitch, so several dice never click in unison.
