Granular Cloud Drone

How it's made

Source

overlapping sine micrograins, 65-150 events/s, with random phase and 90-240 ms soft windows. A second cloud uses 360-750 ms grains at 18 events/s to bridge the gaps without a static oscillator bed.

Body

grains occupy a continuous pitch distribution around 95-260 Hz and its upper octaves; weak detuned second partials add body, while a low-Q 1.5-4.6 kHz ceiling removes hard edges.

Envelope

rounded attack/release windows suppress grain-boundary clicks; density and spectral centre wander over 8-30 s. A 450 ms entrance and 1.2 s exit frame the requested texture duration.

Modulation

each grain glides by up to 7 percent; cloud pitch and upper-octave balance migrate slowly, producing smeared pitch rather than discrete notes or rhythmic repeats.

Space

parallel three-stage all-pass paths scatter grain edges, with unequal 17-61 ms delays; diffusion is part of the synthetic cloud, not a room tail. Random grain pans retain a centred mono sum.

Variation

seeded event timing, phase, pitch, length, gain and pan; presets provide low velvet, luminous mist, broad suspended haze and a finer mobile cloud through multiple parameter changes.

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