How it's made
- Source
- an energy "charge-up" hum, modelled as a pair of slightly detuned band-limited saw voices plus a triangle one octave below, all driven by one rising pitch curve (about 150–600 Hz over 0.7 s), so the ensemble beats gently like a winding-up motor or capacitor.
- Body
- a low-pass filter opens along the same curve (about 500 Hz to 5 kHz) so the hum grows brighter as it rises; a band-passed air layer (1–4.5 kHz) fades in with the crescendo to add shimmer and tension.
- Envelope
- the hum starts at about −30 dB and swells on a convex curve to full level at 0.7 s (the crescendo of a held press); a 6 ms release leaves a clean gap before the click.
- Release click
- at 0.72 s a 2 ms high-passed noise tick excites two damped modes (about 2.6 kHz and 6 kHz, 12–25 ms) and a soft 220 Hz thock, marking the moment the action triggers.
- Variation
- `rng` mistunes the voices by ±1.5 % and `detune` sets the beating; presets differ in start pitch, rise range, brightness and click weight.
