How it's made
Source
dozens of tiny struck glass or metal slivers, each excited by a ~0.5 ms noise tick that is followed by a nearly pure ring. There is no sustained source; the sparkle is a cloud of short events.
Body
every ping is a sine on a pentatonic-like pitch between 2.4 and 10 kHz plus a weak 2.76x inharmonic partial (glass-bar stretch) that dies in a third of the time; partials above 14 kHz are never created.
Envelope
a 1 ms onset avoids clicks, then each ping decays exponentially over 40-250 ms. The event density falls off like a power law over the length, so the cloud thins out and the last pings are sparse.
Events
onsets are drawn from `rng` with a skew (u^1.8); strength, pitch, pan and decay vary per ping.
Air
a very quiet band-passed noise shimmer (5-9 kHz) follows the cloud density and fills the gaps.
Variation
`density` sets the ping count, `pitch` the register, `ring` the decay, `spread` the stereo width; presets move between a dense dust burst, a sparse twinkle and a long, soft shimmer.
