Airy White Noise Band 180-950Hz — 2.6Hz Binaural, 3 Hours

Three hours of synthetic ambient sound built from scratch — no field recordings, no instruments. The bed is white noise, but not the harsh kind: it is high-passed at 180Hz and low-passed at 950Hz, so the rumble and the hiss are both gone and what remains is a narrow, weightless band of air sitting close to the ear. The mix is deliberately near-mono, so it feels close rather than wide. Under that sits a binaural element on a 148Hz carrier with a 2.6Hz offset between the ears, plus a very quiet upper shimmer band and a barely-there low pad that keeps the mix from going brittle. HEADPHONES: the binaural layer only exists as an L/R difference, so it needs headphones or earbuds to be heard at all. On speakers the track still works — it simply plays as a plain filtered noise bed. Every layer breathes on its own slow cycle — 620, 880, 1340 and 455 seconds — and because those periods do not divide into each other, the layers never line up the same way twice across the full three hours. There is no loop point. Rendered at -16 LUFS with a 12-second fade in and a 30-second fade out, no transients anywhere. Headphones recommended — this track contains binaural layers.
