How it's made

Source

two short pitched blips from a small electronic sounder, like a muted marimba tine: a sine fundamental with a 3 ms soft attack and a faint band-passed noise tick for the onset.

Body

fundamental plus 2x and 3x partials that die 2-3x faster than the fundamental, so each blip starts bright and settles to a rounded tone; a short low sine drop (180 -> 90 Hz) under the second blip adds the weight of a "firm end".

Envelope

blip 1 rings about 0.12 s, blip 2 about 0.11-0.16 s and ends in a fast damped cut, so the cue closes decisively instead of trailing off; total length is about 0.4 s.

Variation

`pitch` sets the upper note, `interval` the descent (a third to a fifth), `spacing` the gap between blips, `firmness` the thump and the speed of the final damping, `brightness` the upper partials; `rng` detunes the partials by under 0.3 % and varies the tick.

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