How it's made
- Source
- a stretched elastic band under growing strain. A soft triangle/sine pair carries the pitch of the tension; a faint band of pink noise stands for the fibres creaking as they are pulled.
- Body
- the tone glides upward on a decelerating curve (the band gets stiffer the further it is pulled); a low-pass opens with the pitch so the tone gains a little edge but stays soft; a detuned second voice adds a slow beating shimmer; the noise band-pass follows the pitch at about 5x.
- Envelope
- a 40 ms onset ramp, a steady swell to the end, then a short smooth fade at the top of the glide, so the sound stops while still rising and the tension is never released.
- Variation
- `rng` detunes the start pitch by a few cents and offsets the shimmer phase; parameters set the pitch span, the softness, the creak amount and the length.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| length | 0.3 – 0.9 | 0.6 | s | Length |
| pitch | 140 – 520 | 260 | Hz | Start pitch |
| span | 0.2 – 1.2 | 0.7 | — | Rise (octaves) |
| softness | 0 – 1 | 0.6 | — | Softness |
| creak | 0 – 1 | 0.35 | — | Elastic creak |
| seed | int | 1 | — | Variation, reproducible |
