Plague Swarm Overhead

How it's made

Source

a cloud of beating wings; ten detuned, band-limited saw clusters at 85-230 Hz model asynchronous wing strokes and their harmonics, with independent 0.4-1.1 Hz frequency wander.

Body

wing turbulence is decorrelated pink noise above 160 Hz; broad 0.7-3 kHz bands flutter at each cluster's wing rate. Low-Q filtering avoids fixed whistles or metallic resonances.

Rattle

dense bipolar membrane impulses (1800-9000/s per side), filtered to 1.3-6.8 kHz, thicken near the centre of the pass; no isolated hard clicks or artificial reverberation.

Envelope

one cloud approaches over 40 percent of the requested duration, crests overhead, then recedes. Air absorption opens from 1.2 to 6.8 kHz and closes as the cloud moves away.

Movement

independent 0.2-0.7 Hz patches breathe inside the global swell; wing pitch falls by about 7 percent during passage. Cluster pans move left to right across a wide diffuse bed.

Variation

seeded phases, tuning and patch motion; presets change altitude, wing scale, membrane density and stereo spread. The default pass lasts 25 seconds, scaled for other lengths.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
