How it's made
- Source
- a fingertip driving a key stem down in a mechanical switch. Two impacts: a sharp plastic click (switch leaf or stem tick, under 2 ms, broadband above 1.5 kHz) and, 8–16 ms later, the keycap bottoming out on the plate, a duller 3–8 ms low-passed thump.
- Body
- the keycap and switch housing ring in two damped plastic modes (about 2–4.5 kHz, ratio ≈ 1.9, 12–40 ms); the case and plate act as a hollow cavity around 140–300 Hz whose short sine "thock" drops about 25 % in pitch as it decays.
- Envelope
- click attack under 0.3 ms, modes fall 60 dB in about 25 ms; thock attack 1 ms, decay 40–70 ms; everything is silent by roughly 0.1 s, nothing sustains.
- Variation
- `rng` mistunes the modes by ±3 %, the bottom-out delay by ±8 % and the noise bursts, so repeated keystrokes are not identical.
- Layers
- click (contact + modes) and thock (cavity sine + low noise thump) are mixed in a ratio set by `thock`; presets move the balance between tactile click, deep thock and light laptop-style taps.
