Pink noise on its own, nothing layered underneath it, which makes this the warmer sibling of the site's other pure-noise focus preset. Pink noise falls off faster at the high end than white does, so this reads closer to an old reading room with the radiator on than to an air conditioner.
If White Study's flatter white-noise version feels a little too sterile for reading or long writing sessions, this is the softer alternative built around the same idea: masking noise for concentration, no melody, nothing to notice.
Even something this minimal is generated live on your device rather than a recorded loop, so it never actually reaches an end or a seam.
StillTune composes endless, ever-changing music for sleep, focus and relaxation. Real melody and instruments, generated live, with no audio files. Explore more sounds.
