How it's made
- Source
- an electrically driven piezo diaphragm, centred at 3.15 kHz, with weak second and third drive harmonics. Additive sine partials keep the piercing tone free of square-wave aliasing.
- Body
- a weak 1.47x diaphragm/housing mode decays in 55 ms; band-limited drive noise sits far below the carrier. Upper harmonics briefly brighten on startup as the diaphragm settles.
- Envelope
- 7 ms attack, 0.38-0.52 s powered plateau, 24 ms shutdown with a 35 ms resonant release. A 0.7 percent pitch overshoot settles in 25 ms; slow 37 Hz amplitude ripple models drive instability.
- Pattern
- onsets at 0.02, 1.02 and 2.02 seconds in each four-second group, followed by silence. Events repeat indefinitely; all releases finish before the loop seam.
- Variation
- seed sets device tuning within 0.15 percent. Presets model a standard diaphragm, a small bright buzzer, a lower-pitched diaphragm and a rougher drive circuit; timing stays recognisable.
- Space
- dry centred source, without room reflections, suitable for placement in a scene.
