How it's made
- Source
- a small electric drive spinning up (band-limited saw plus a triangle sub-octave, 55 → 330 Hz) with gear/bearing air noise; then a synth beeper (square + sine) playing short rising chirps; then a servo whine (saw, 1.1 kHz falling to 700 Hz) as the actuators lock into position.
- Body
- the motor body is a low-pass whose cutoff opens from 300 Hz to about 2 kHz as rpm rises, with a narrow band (Q ≈ 3) riding at 5x the fundamental for the whir; the beeper is low-passed at 3.5-6 kHz to stay clean.
- Envelope
- whir swells over 1.15 s, holds, then drops away by 1.75 s; beeps are 75 ms each with a 4 ms attack and a quick decay, spaced about 105 ms apart from 0.92 s; the servo settles over 0.4 s from 1.5 s with a 20 ms attack and a long decay, ending with a faint latch tick; everything is faded out by 2.0 s.
- Variation
- `rng` shifts beep pitch (±2 %) and spacing; `pitch` scales every frequency, `whir` and `beeps` balance the layers, `settle` sets the servo level, `brightness` opens the filters.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| pitch | 0.6 – 1.8 | 1 | — | Scales the size of the robot: low is big, high is small |
| whir | 0 – 1 | 0.7 | — | Motor whir |
| beeps | 2 – 6 | 4 | — | Beep count |
| beepLevel | 0 – 1 | 0.6 | — | Beep level |
| settle | 0 – 1 | 0.6 | — | Servo settle |
| brightness | 0 – 1 | 0.5 | — | Brightness |
| seed | int | 1 | — | Variation, reproducible |
