White Noise Gradient from Light to Deep
Progressive Spectral Shift from Bright White Noise to Deep Brown

Most colour noise recordings maintain a static frequency profile — white stays white, brown stays brown. This recording takes a different approach: beginning with standard white noise and gradually shifting the spectral balance toward deeper frequencies over the first sixty minutes, passing through pink noise and eventually settling into brown noise territory.
The transition is imperceptible in real time — at any given moment, the noise sounds static, but comparing the first minute to the sixtieth reveals a complete transformation. The design mirrors the brain's natural preference during sleep onset: lighter, more stimulating frequencies help mask the environmental sounds that keep you awake, while the deeper frequencies your brain encounters as sleep deepens promote sustained, undisturbed rest.
After the initial sixty-minute descent, the deep brown profile is maintained for the remainder of the session. Think of it as a noise colour that puts you to sleep and then stays asleep with you.
