How it's made
- Source
- two soft, tuned electronic tones played in quick succession, like a pair of felt-struck glass tines or a gently gated sine synth. There is no noise strike: the onset is a smooth 8–15 ms swell, so no click.
- Body
- each note is a pure fundamental (700–1400 Hz) plus a very quiet 2nd partial (2.0×) and 3rd partial (3.0×) that decay faster than the fundamental, giving an "open and clear" colour that dulls into a pure tail.
- Envelope
- note 1 swells in ~10 ms and falls 60 dB in ~0.14 s; note 2 starts 85–100 ms later, a perfect fourth to fifth higher and slightly longer, so the pair reads as "rising / now listening". The whole cue is ~0.3 s.
- Variation
- `rng` detunes each partial by ±0.1 % so the cue is not mechanically identical; macros set pitch, interval, note spacing, ring and brightness. Presets change register, interval and softness.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| pitch | 500 – 1500 | 880 | Hz | Pitch |
| interval | major-third · fourth · fifth · octave | fifth | — | Interval |
| spacing | 0.05 – 0.16 | 0.09 | s | Spacing |
| ring | 0.06 – 0.3 | 0.11 | s | Ring |
| softness | 0 – 1 | 0.5 | — | Softness |
| brightness | 0 – 1 | 0.4 | — | Brightness |
| seed | int | 1 | — | Variation, reproducible |
