Brown Noise

Free brown noise generator with a deep, low rumble like distant surf. Popular for focus and for masking traffic and low-frequency background hum.

Volume

Stopped.

Weighted towards the low end again, twice as steeply as pink — a deep rumble closer to distant surf or heavy rain than to a hiss. Generated in your browser rather than streamed, so nothing is downloaded and it starts quiet and fades in.
