Turn Signal Tick

How it's made

Source

alternating pull-in and spring-return of an automotive flasher relay. Reuses the pinned Relay Click model: 0.9–1.6 ms band-limited impacts with diminishing contact rebounds over 2–8 ms.

Body

armature modes near 2.3, 3.9 and 6.5 kHz decay in 11–26 ms; the plastic enclosure adds 0.8 and 1.4 kHz modes lasting 9–17 ms. Size and damping model the relay and dashboard enclosure.

Envelope

rounded 0.12 ms attacks and falling contact brightness; each action settles within 45 ms. The release action is softer and lower than pull-in; the space between actions remains silent.

Rhythm

two complete on/off cycles per 2 s by default, with actions every 0.5 s. A 20 ms phase offset leaves both loop boundaries silent. Fast flashing uses three complete cycles per 2 s.

Variation

event-specific seeded streams give slight modal and contact variation, without timing drift. Contrast controls the return level; presets change size, damping, rebound and cadence together.

Space

dry, centered mono mechanical source; no engine rumble, electrical hum or room reverberation.

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