How it's made
- Source
- a shield is an energy field sustained by a power core. Three parts: a mains-like low drone, a thin plasma shimmer riding on it, and corona discharge, the sizzle of tiny sparks leaking from the surface.
- Body
- the drone is two slightly detuned saw/triangle oscillators at about 55 Hz (beat of 0.25 Hz) plus a sine sub, low-passed near 300 Hz so only the lower harmonics speak. The shimmer is a pair of sines near its 4th and 6th harmonic (about 220 and 330 Hz, detuned apart) and a band-passed noise veil at 1.2 kHz.
- Envelope
- steady by design. A slow swell (0.5 Hz, 4 cycles per 8 s) pulses the drone amplitude by about 25 %, a 0.25 Hz sweep opens and closes the drone filter, and a random drift gates the sizzle so sparks arrive in clusters, never as a machine-gun pattern.
- Sizzle
- sparse unipolar impulses (crackle) high-passed at 3.5 kHz and band-limited around 6.5 kHz, independent in left and right so the field feels wide; its level follows the "Sizzle" parameter.
- Variation
- `rng` detunes the oscillators by a few cents and drives the drifts; presets change the drone pitch, swell speed, shimmer amount and sizzle level (idle core, charged shield, overload, distant barrier).
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| pitch | 40 – 90 | 55 | Hz | Drone pitch |
| swell | 0.25 – 1.5 | 0.5 | Hz | Swell rate |
| shimmer | 0 – 1 | 0.4 | — | Shimmer |
| sizzle | 0 – 1 | 0.4 | — | Sizzle |
| warmth | 0 – 1 | 0.4 | — | Drone brightness |
| spread | 0 – 1 | 0.7 | — | Width |
| seed | int | 1 | — | Variation, reproducible |
