How it's made
- Source
- stress release in thick lake ice; a rounded 4 ms filtered fracture excites plate vibration.
- Dispersion
- flexural group speed increases with frequency. Three delayed wave packets approximate high frequencies arriving first: f = floor + sweep / (1 + t/tau)^2, not a linear laser pitch bend.
- Body
- inharmonic plate modes at 0.72, 1, 1.63 and 2.39 times the low anchor; T60 1.5-4.3 s.
- Envelope
- packets bloom in 6-18 ms, descend from roughly 3 kHz toward 200-600 Hz, then ring for seconds. Higher branches decay faster; a smooth final taper reaches zero at 4.85 s, without a hard cutoff.
- Space
- weak delayed, darkened propagation paths widen the tail; no room reverb or continuous wind bed.
- Variation
- seeded tuning +/-1.2%, onset offsets and lateral position. Anchor sets ice scale, dispersion sets travel time, ring sets damping, distance removes high frequencies; twin adds a second stress release.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| anchor | 160 – 480 | 290 | Hz | Ice scale |
| dispersion | 0.1 – 0.42 | 0.22 | s | Dispersive travel |
| ring | 2.2 – 4.3 | 3.8 | s | Plate ring |
| distance | 0 – 1 | 0.25 | — | Distance |
| release | single · twin | single | — | Stress release |
| seed | int | 1 | — | Variation, reproducible |
