Streak Milestone

How it's made

Source

a small struck glass-metal bell played as a quick rising arpeggio, finished by a longer bell on the top note and a few high glints. Each note is a 1–2 ms soft strike (high-passed noise) exciting sine partials.

Body

every note is a fundamental plus stretched partials (2.0×, 2.76×, 5.4×) with amplitudes falling off; upper partials decay 2–6× faster than the fundamental, so the strike is bright and the tail pure.

Arpeggio

4–6 notes of a major scale shape (root, 3rd, 5th, octave, 10th, 12th) 55–90 ms apart; notes overlap and rise in level, so the figure leans into the last note, which rings longest (`ring`).

Sparkle

sparse 4–8.5 kHz sine pings of 60–150 ms with random pan, starting after the top note and thinning out over about 0.9 s, like light catching on metal.

Variation

`rng` detunes partials by ±0.2 %, jitters note timing by ±3 ms and varies glint pitch, pan and level; presets change pitch, note count, tempo, bell brightness and sparkle density.
