Gentle Breeze

How it's made

Source

low-speed outdoor air passing broad surfaces, represented by independent pink-noise turbulence and a quieter white-noise air veil. Continuous friction, without leaves or edge whistles.

Body

broad Q 0.55 turbulence centred at 220-1150 Hz; a 65 Hz high-pass removes microphone buffeting. A separate 700-4200 Hz air layer gives breath without sharp hiss. A faint 85-240 Hz pink-noise cushion adds passing pressure, rather than infrasonic rumble. All filters are broad and damped.

Envelope

a slow seeded gust combines with one smooth wave per requested loop and a small second harmonic; level rises quadratically and filter bandwidth opens with air speed. At 10 seconds the main rise/fall is 10 s and the smaller eddy is 5 s. A steady floor keeps lulls alive.

Layers

pressure follows the main swell, while the air veil has independent 0.24 Hz wander and gentler level contrast, modelling small eddies within a larger air mass. Highs roll off twice.

Space

independent left/right noise with shared slow motion preserves a stable, diffuse image; width is adjustable. Dry outdoor perspective with no reverberation or fixed pitched resonances.

Variation

named seeded streams control gusts, air and pressure. Brightness changes air absorption, motion changes gust contrast, air changes small-eddy balance, and spread changes stereo extent. Presets offer sheltered warmth, exposed airy flow, stronger rolling swells and distant dark air.

Loop

10 s default; periodic motion fits the requested duration, with the engine crossfading stochastic turbulence at the seam. No attack transients or hard gating.
