How it's made
- Source
- hand-shaken thin steel sheet; distributed pink/white excitation follows irregular 2-6 Hz flexes. Rounded 18-45 ms excitation edges represent buckling, rather than a hard mallet strike.
- Body
- broad bending modes at 48-590 Hz shift by 5-18 percent as sheet curvature changes; overlapping low-Q bands create thunder-like rumble without a single pitched bass oscillator.
- Shimmer
- paired inharmonic modes at 730-4700 Hz ring for 0.25-0.95 s, with 1-5 Hz beating; high modes decay sooner, and their excitation darkens as the hands stop moving.
- Envelope
- 35 ms onset, strongest shaking in the first 1.4 s, then relaxing flexes and a damped tail; total audible duration is 2.5-3.05 s, followed by silence. No room reverb is baked in.
- Variation
- seeded mode detuning, independent excitation and wandering curvature prevent rigid pulses. Size sets mode scale; shake rate, flex depth, shimmer and damping distinguish four useful sheet gestures.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| size | 0 – 1 | 0.7 | — | Sheet size |
| rate | 2 – 6 | 3.2 | — | Shake rate |
| flex | 0 – 1 | 0.7 | — | Flex depth |
| shimmer | 0 – 1 | 0.5 | — | Metal shimmer |
| damping | 0 – 1 | 0.3 | — | Hand damping |
| seed | int | 1 | — | Variation, reproducible |
