Noise Wash Drone

How it's made

Source

continuous turbulence, modelled with independent pink and white noise; no pitched excitation.

Body

three broad resonant bands sweep through 100 Hz–6.3 kHz, with Q 1.2–6. Their independent non-harmonic trajectories imitate changing spectral emphasis in distant surf, without cavity whistles.

Layers

a quiet pink-noise bed at 65–650 Hz supports the moving bands; a quiet 1.8–6 kHz white-noise veil supplies airborne spray. A final 7 kHz low-pass softens the top; a 45 Hz high-pass removes drift.

Envelope

12–32 s spectral cycles are bent by random wander; 7–19 s overlapping swells change level by a few dB without gaps. A 0.8 s entrance and 1.8 s release frame any requested render duration.

Space

independent left/right turbulence shares band motion for a stable image; no combs or reverb.

Variation

seeded phases, band offsets and drift paths; colour sets spectral height, motion sets sweep speed, resonance sets band definition, and air balances spray. Presets span deep, airy, hollow and tidal.

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