Frequently asked questions
What is the difference between the noise colors?
White noise is flat across frequencies, pink rolls off the highs for a softer sound, and brown is even deeper and rumblier.
Does it loop seamlessly?
Yes — a short buffer of generated noise is looped continuously until you press Stop.
