How it's made
- Source
- escaping pressurized air excites two rubber lips; filtered noise supports a fluttering, harmonic-rich membrane tone at 150-650 Hz, rather than a pure whistle.
- Body
- the neck adds broad resonances near 1 and 2.2 kHz; second and third partials follow lip tension.
- Envelope
- a 15 ms opening leads to a strong jet, then pressure and brightness decline over about 2 s.
- Modulation
- irregular 25-60 Hz lip flutter drives both airflow and pitch; slower rising and falling tension bends and lateral motion suggest the uncontrolled flight of the shrinking balloon.
- Events
- in the final quarter, continuous flow breaks into four tapered, diminishing 35-85 ms sputters.
- Variation
- seeded tension drift, flutter phase and sputter timing; presets vary neck pitch, flutter, flight length and terminal instability. Dry, with distance represented by falling level and brightness.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| length | 1.4 – 2.6 | 2 | s | Flight length |
| pitch | 160 – 460 | 280 | Hz | Neck tension |
| flutter | 25 – 60 | 42 | — | Lip flutter rate |
| air | 0 – 1 | 0.5 | — | Air leakage |
| wobble | 0 – 1 | 0.65 | — | Flight instability |
| 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.
