How it's made
- Source
- electrical white noise, modelled as independent random samples at 48 kHz; equal power per Hz.
- Layers
- independent left and right excitation streams; width blends their mid and side components. There are no oscillators, impulsive events, room reflections or resonant bodies.
- Body
- full bandwidth bypasses the low-pass; only a 10 Hz DC blocker removes sub-audible offset. Optional Butterworth low-pass at 6.5 or 12 kHz and high-pass at 20-600 Hz model output bandwidth.
- Envelope
- constant sustain, no amplitude or spectral modulation; the host crossfades the 10 s loop.
- Variation
- seeded samples vary the microscopic waveform, never the macroscopic spectrum or level. Presets provide full stereo, coherent mono test noise, soft sleep bandwidth, and speech masking.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| bandwidth | full · soft · gentle | full | — | Upper bandwidth |
| lowCut | 20 – 600 | 20 | Hz | Low cut |
| spread | 0 – 1 | 1 | — | Stereo width |
| 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.
