The Colors of Noise

Equal energy across all frequencies. Excellent for masking sharp sounds like speech.

Balanced and less harsh, like steady rain. Great for all-purpose focus.

A deep, rumbling sound like a strong waterfall. Best for sleep and masking low-frequency noise.

Hissy and bright, with more power at higher frequencies. Used for focus and audio dithering.

Very bright and intense high-frequency hiss. The opposite of brown noise.

The "sound of nature," concentrated in the mid-range frequencies. Very calming.

Perceptually uniform loudness across frequencies, tailored for the human ear.
