Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get TD17HP1418@1 --preset soft -o mention-double-ping.wav
How it's made
Source
a small struck metal tine or glass rim, hit twice at the same pitch by a light hard striker; the strike is a 1–2 ms high-passed noise tick that excites the body.
Body
a fundamental near 1.8 kHz plus stretched partials (2.76×, 5.4×) from a free bar; the upper partials decay 2–4× faster than the fundamental, so each ping starts bright and ends as a pure tone.
Envelope
a 1.5 ms onset ramp, then an exponential decay of 0.1–0.35 s per ping; the second ping lands 70–220 ms after the first, slightly softer, so the pair reads as one urgent gesture.
Variation
`rng` detunes each partial by a fraction of a percent; the macros set pitch, spacing, ring and brightness; presets trade sharpness, spacing and softness for different surfaces.
