Rumbli

Brown noise, deep and steady

Lower and softer than white noise. A favourite for heavy sleepers and noisy homes.

What brown noise is

Brown noise puts more of its energy in the low end, falling 6 dB per octave. It sounds like a deep, steady rush, like a strong waterfall heard from a distance.

Three shades of low

Brown for a warm, even rumble; deep brown for something darker; deep rumble for a slow sub bass swell that is best with a speaker or AirPlay.

Mix it with a layer

Add the shush or a slow heartbeat on top of any sound, and save the mix to use again with one tap.

Does it loop?

No. Brown noise is made live on your phone, so it never repeats.
