Green Noise

How it's made

Source

many unresolved, distant air and foliage fluctuations form continuous pink turbulence; independent pressure fields model the spatial average, without identifiable drops or leaf clicks.

Body

a broad Q 0.55 band-pass at 380–850 Hz gives a mid-centred mound, not a pitched cavity. Two-pole high/low cuts at 140–230 Hz and 1.2–2.4 kHz soften both spectral edges.

Layers

a coherent mid bed anchors the image; independent left/right turbulence surrounds it. A quieter white-noise band at 1.55 times the centre adds distant, air-absorbed foliage texture.

Envelope

continuous sustain over the 10 s loop, without attacks, pauses or rhythmic pumping; the engine crossfades the boundary. Random gain wander stays within +/-4 percent at full movement.

Modulation

smoothed 0.09–0.17 Hz wander shifts broad bands by at most +/-6 percent; separate layer envelopes prevent a synchronized gust while keeping the overall level steady.

Variation

named seeds separate every field. Sheltered grove is warm and close, open bank is wider and airier, and still focus is a narrow, nearly stationary mid bed with restrained stereo spread.
