    How it works

    This is a live, generative soundscape — not a looped recording. Press play and it builds the blend above; every sound has its own fader, so you can tune brown noise for concentration to taste. With Adaptive on, the mix shifts subtly with the time of day and how long you've been listening — and tells you why.

    FAQ

    What's the difference from white noise?

    Brown noise has more low-end energy, so it sounds deeper and softer — many people find it less fatiguing for long sessions.
