Sync Complete

How it's made

Source

two layers. A soft air whirl (band-passed noise plus a gliding sine) that sweeps upward in about 0.35 s, then a small struck glass or metal tine played as a suspended note that resolves to a consonant dyad.

Body

the whirl is a band-pass (Q 2.5) climbing from 350 Hz to 2-4 kHz; the left and right channels use independent noise and a 25 ms offset so the sweep seems to circle the listener. Each chime note has a fundamental plus stretched partials (2.01x, 3.02x); upper partials decay faster, so the tail is pure.

Envelope

the whirl swells in 0.12 s and fades as the first chime lands (0.30 s). Notes strike in 4 ms and decay exponentially (0.3-1.4 s); the resolving note and the root enter 0.13 s after the suspended note.

Variation

`rng` detunes each partial by a fraction of a percent and varies the whirl noise. `pitch` sets the root, `whirl` the level and span of the sweep, `ring` the decay, `brightness` the upper partials.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
