About White Noise Generator

The White Noise Generator is a 100% client-side audio tool powered by the Web Audio API that generates and plays noise sounds in real-time directly in your browser. Perfect for soothing babies, improving sleep quality, boosting focus, and enhancing meditation.

Three noise types for every need. White noise has uniform energy across all frequencies, ideal for masking environmental sounds and aiding sleep. Pink noise features a 1/f spectrum that sounds natural and soothing, perfect for focus and relaxation. Brown noise has deep, rumbling 1/f² characteristics, best for deep sleep and meditation.

Fade-Out feature improves sleep quality by gradually lowering volume during the final minutes before the timer ends. Rather than stopping abruptly, the sound gently fades away, creating a natural transition to sleep without waking the listener—especially important for soothing babies.

Tone Adjustment lets you customize the frequency profile. Boost bass for relaxation and deep sleep, or emphasize treble for focus and wakefulness. Find the perfect frequency balance for your ears and sleep needs.

Comprehensive controls including timers (15 min to 2 hours) and smooth volume adjustment. All processing stays entirely in your browser, protecting your privacy completely. No installation or sign-up needed.

How to use White Noise Generator

  1. Select a noise type (White, Pink, or Brown) by clicking a card. Each displays the noise characteristics and recommended uses.
  2. Adjust volume with the slider (0%–100%) and customize tone (Bass to Treble) to match your audio preferences.
  3. Set a timer (15 min to 2 hours) and optionally enable Fade-Out to gradually lower volume during the last 1–5 minutes.
  4. Click Play to start. Noise plays until the timer expires and gradually fades out if enabled. Click to stop anytime.
