Free White Noise Generator — Sleep Aid & Focus Sound

Generate continuous white, pink, or brown noise for sleep, focus, or masking background sounds. Mix multiple noise types and adjust volume.

How It Works

Select a noise type (white, pink, brown), adjust the volume, and click Play. Generated using Web Audio API nodes with filtered random signals — no streaming, fully private.

Tips for Best Results

  1. 1. White noise has equal energy per frequency — sounds like static.
  2. 2. Pink noise decreases at higher frequencies — sounds like rainfall.
  3. 3. Brown noise drops off faster — sounds like ocean waves or heavy wind.
  4. 4. Mixing multiple types creates a customized sound profile.

No server involved — everything runs in your browser with complete privacy.

Frequently Asked Questions About White Noise Generator

Q1What is the difference between white, pink, and brown noise?

White noise distributes equal energy per frequency. Pink noise decreases energy at higher frequencies (sounding softer, like rainfall). Brown noise drops off even faster at high frequencies (sounding deep, like ocean waves or heavy wind).

Q2Can white noise help with sleep and concentration?

Yes! Background noise masks sudden ambient sounds, helping relax your brain, improve focus, and promote deeper sleep.

Q3Does this generator loop smoothly without popping sounds?

Yes. Audio buffers are generated dynamically using Web Audio API buffer synthesis, eliminating seams, gaps, or clicks.
