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.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| density | 10 – 60 | 36 | — | Density |
| pitch | 2400 – 5200 | 3600 | Hz | Pitch |
| ring | 0 – 1 | 0.5 | — | Ring |
| spread | 0 – 1 | 0.7 | — | Stereo spread |
| shimmer | 0 – 1 | 0.4 | — | Air shimmer |
| length | 0.5 – 1.4 | 0.7 | s | Cloud length |
| seed | int | 1 | — | Variation, reproducible |
The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
