VOL Silent
Steady blue noise, generated live in your browser and looped seamlessly. Works on speakers or headphones, no app and no download. This is a bright color with almost no low end, so it has no bass control; Smooth rolls off the harsh highs (Smooth or Super), tuned for this color. Volume starts low on purpose: raise it to a comfortable, even wash.

What is blue noise?

Blue is a bright, high-frequency-weighted noise (the inverse of brown), a crisp airy hiss often used to mask high-pitched distractions. People play it to stay alert, mask high-pitched sounds, and keep a crisp, bright background for focus. On this page you can play it free, with no app and no sign-up: just tap the disc above.

It pairs beautifully with breathwork, journaling, yoga, or simply a few quiet minutes with your eyes closed. Start low, stay comfortable, and let the sound do the work.
