How it works and good to know
White, pink and brown noise and the rain-like and fan-like sounds are all synthesized from numbers and filtered in this browser — no recorded audio is downloaded. Left and right get different noise, and loop seams are crossfaded so there are no clicks. The sleep timer runs 15–90 minutes and fades out over the last 30 seconds. When a phone screen locks, playback may stop depending on browser and device settings.
