How it's made
Source
a dry clock escapement ticking against a sub-bass pulse. Each tick is a 1–2 ms noise click that excites a small wooden body; the pulse is a damped low sine thump, like a muffled kick or heartbeat.
Body
ticks ring in a few damped modes (10–30 ms) plus a short hollow knock at 600–800 Hz; "tock" beats are softer and lower. The pulse falls from ~90 Hz to ~55 Hz over 60 ms and decays in ~0.4 s.
Envelope
ticks are strictly periodic (1–4 per second) and the pulse lands on every 1st–4th beat; a slow swell of exactly one loop cycle raises the pulse level, so tension builds and releases without a seam.
Variation
`rng` varies each tick's level and tuning by a few percent; presets change tempo, pulse weight and tick colour (thriller, countdown, wall clock, heartbeat).
