A sound machine without the hardware
Everything a physical white-noise machine does, in a browser tab:
- Seven noise colors for sleep, focus, and relaxation.
- A tone control to dial in exactly the sound you like.
- A sleep timer with a smooth fade-out.
- Gentle Waves mode for a natural, breathing rhythm.
- Works on any device with a browser — no purchase, no app.
Great for babies, sleep, and focus
Use white or pink noise to settle a baby (keep the volume low and the device well away from the crib), brown noise for deep sleep and relaxation, and grey or brown noise for focused work. Set the timer and let it fade out on its own.
