How it's made
- Source
- a small electromechanical buzzer driven by a gated square wave. Two square-ish oscillators a few cents apart (plus a pulse-width-narrowed twin) give the reedy, slightly beating buzz; a sine sub at the fundamental adds weight.
- Body
- the small enclosure rolls everything above about 0.5–1.6 kHz off (low-pass, Q 0.8), so the square's upper harmonics are felt as a dull rasp rather than a bite. The cutoff closes a little over each pulse as the driver loses energy. A faint low-passed noise burst (under 500 Hz) gives the contact thump at each onset.
- Envelope
- two pulses of about 0.13 s separated by a 0.05 s gap; 6 ms raised-cosine style ramps in and out so the gate never clicks. The second pulse is about a minor third lower, which reads as "denied".
- Variation
- `rng` mistunes the oscillator pair by up to 6 cents; presets move pitch, dullness, grit and pulse spacing (soft thud, standard buzz, low growl, quick double-tap).
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| pitch | 90 – 260 | 150 | Hz | Pitch |
| dullness | 0 – 1 | 0.5 | — | Higher values roll off more of the upper harmonics |
| grit | 0 – 1 | 0.35 | — | Reedy beating between the detuned oscillators |
| pulse | 0.08 – 0.18 | 0.13 | s | Pulse length |
| gap | 0.03 – 0.1 | 0.05 | s | Gap |
| drop | 0 – 1 | 0.5 | — | How far the second pulse falls in pitch (up to a fourth) |
| seed | int | 1 | — | Variation, reproducible |
The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
