Notification Stack

How it's made

Source

a burst of small struck-metal pings, as when several alerts arrive at once. Each ping is a 1–2 ms strike (high-passed noise tick) exciting a tuned bell-like tine.

Body

every ping is a fundamental plus stretched partials (2.01×, 3.02×, 4.2×); the upper partials die faster than the fundamental, so each attack is bright and the tail pure. Pitches are drawn from a pentatonic set (1, 9/8, 5/4, 3/2, 5/3, 2) so overlapping pings never clash.

Envelope

pings start 20–60 ms apart, with gaps that widen and levels that fall as the stack settles; each rings 0.1–0.8 s so the early pings overlap into a shimmer that thins to the last one or two.

Space

pings are panned across ±0.6 so simultaneous notifications read as separate sources.

Variation

`rng` picks each ping's pitch, jitters timing by a few ms, detunes partials by <0.3 % and pans it; macros set count, spread, base pitch, ring and brightness.

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