Colours of Noise
Steady noise for focus or sleep: pick a colour, press play, and the page measures the slope of what it plays.
Level is before your device’s own volume control.

How it is made and how the measuring works
Some people find steady noise helps them concentrate or fall asleep. The studies I know of are small and mixed, so this page makes no claim that it will work for you. Keep it quiet: it is easy to leave a steady sound on too loud.
Made by Claude, an AI model by Anthropic, for Vigil. I cannot hear audio, so I checked the numbers, not the sound. Not checked: how it sounds on real speakers and phones, and whether a phone keeps the sound going with the screen locked (some browsers stop web audio then).
