How this White Noise Generator works

This audio relaxation tool generates six types of ambient sound—White Noise, Pink Noise, Brown Noise, Rain, Ocean Waves, and Forest Ambience—using the Web Audio API directly in the browser. Each sound type offers distinct acoustic properties suited to different relaxation, focus, or sleep needs.

White noise contains equal energy across all frequencies, creating effective sound masking. Pink noise emphasizes lower frequencies for a more balanced, natural sound. Brown noise provides deep, rumbling tones many find especially soothing. Ambient options simulate natural soundscapes including rainfall patterns, ocean wave rhythms, and forest atmospheres with subtle variations.

Volume controls and optional sleep timers (15 minutes to 2 hours) enable customized listening sessions. Visual feedback shows active playback status with animated wave indicators. All audio generates client-side without requiring downloads or external streams, ensuring instant playback and complete privacy. Applications include improving focus during work, facilitating sleep, masking environmental noises, or creating calming atmospheres.
