How it's made
- Source
- a handful of tiny struck glass or metal tines, played as a fast rising arpeggio of major-pentatonic notes. Each strike is a 0.5 ms high-passed noise tick that only colours the very first moment.
- Body
- every glint is a sine fundamental (1.6–8 kHz) plus a stretched upper partial (≈ 2.76×) that dies about three times faster, and a second fundamental detuned by 0.3–0.7 %, which beats slowly and gives the tail its shimmer. Upper partials are dropped above 12 kHz to stay clean.
- Envelope
- 1.5 ms onset ramp (no click), then an exponential decay of 60–250 ms per glint; the last note of the run rings about twice as long, so the cluster ends in a fading, shimmering sparkle.
- Variation
- `rng` jitters note timing (±8 %), tuning (±0.2 %) and scatters each glint across the stereo field; presets change pitch range, run length, speed and shimmer.
