Leaves Rustle

How it's made

Source

a moving body pushes through a bush; leaf faces scrape and dry edges buckle and release. Pink/white friction, filtered micro-impulses and short noise contacts model these separate actions.

Body

broad leaf friction spans 450 Hz-6 kHz; small dry edges extend to 8 kHz. Broad Q 0.55-0.8 bands model damped leaves, with no sustained woody pitch, wind rumble or added reverberation.

Envelope

irregular pushes recur every 0.65-2.05 s, with 45-110 ms attacks and 0.25-0.7 s releases. Contact pressure opens the spectrum and raises crackle density; quiet gaps separate the bursts.

Events

4-55 leaf contacts/s during pushes, each 1.5-5 ms attack and 12-65 ms decay, plus 180-1700 fine edge impulses/s. A softer delayed friction layer models neighbouring leaves settling back.

Variation

seeded timing, pressure, flutter, contact colour, duration and position; pace controls pushes, dryness controls brittleness, leaf size darkens and lengthens contacts, force widens strokes.

Presets

sparse cautious brushing, brittle dry leaves, broad green leaves and vigorous dense passage. Stereo is a close bush-sized field, not an overhead canopy or an environmental wind recording.
