A custom-tuned noise blend sitting between warm pink and deep brown - what the studio calls amber noise. The low end carries the body of brown noise; the midrange is softened and rounded the way a pink slope softens white; the high end is gently rolled off so nothing hisses.

The result is a warm, enveloping masker that feels more like a thick blanket than a flat wall. No movement, no weather, no voices.

Just ten unbroken hours of warm, sleep-shaped frequency. The hand-shaped curve sits especially well on small speakers and phone speakers without losing its masking power.

The amplitude holds completely flat from first second to last. Perfect for noise-sensitive sleepers, cold-climate sleepers, anyone who finds plain brown noise too heavy and plain pink too thin, tinnitus sufferers, light sleepers in small bedrooms, side-sleepers who use a pillow speaker, and listeners who prefer a hand-tuned masking track. Ten unbroken hours of amber carry you from bedtime into morning in one uninterrupted piece. Press play, pull the covers up, and rest.
