How it's made
Source
three layers of a sparkling reveal. (1) a cloud of tiny struck-glass glints, each a pair of sine partials (ratio ≈ 1 : 2.76) with a 1 ms soft onset; (2) a pad of six detuned sine partials on a C6 stack (1046 Hz × 1, 2, 3, 4, 5, 6) shimmering through slow independent tremolos; (3) a band of airy noise whose band-pass centre climbs from 3 kHz toward 9-11 kHz.
Body
glints are drawn from a pentatonic set between 2.1 and 8.4 kHz, so they sparkle without a harsh resonance; the partial stack carries the harmonic colour; the noise band has Q ≈ 1.5; everything is band-limited between 250 Hz and 12.5 kHz.
Envelope
the glint rate swells from 6 to 70 per second toward the reveal point at ≈ 62 % of the length while their pitch drifts upward; the pad and noise crescendo (higher partials enter later, so the spectrum brightens), then a bloom of stacked partials strikes at the reveal and rings out with a 0.5 s decay.
Variation
`rng` jitters glint pitch, timing, strength and pan, partial detune and tremolo phase; presets change the length, glint density, pad weight and bloom size.
