About AmbientNoise.io
AmbientNoise.io is a free, browser-based ambient sound generator designed to help you sleep better, focus harder, and relax more deeply.
Our Mission
We believe everyone deserves access to quality sleep and focus tools without paywalls, subscriptions, or intrusive ads. That's why we created AmbientNoise.io - a completely free service that generates high-quality ambient sounds right in your browser.
How It Works
Unlike other sound apps that stream audio files, AmbientNoise.io uses the Web Audio API to generate sounds directly in your browser. This means:
- No large downloads or buffering
- Works offline once the page is loaded
- Infinite, non-repeating sound
- Complete customization of each sound
- No server costs means free forever
Features
- 25+ synthesized ambient sounds
- Mix multiple sounds together
- Sleep timer with fade out
- Pre-made presets for common use cases
- Keyboard shortcuts for easy control
- Dark theme that's easy on the eyes at night
- Mobile-friendly responsive design
Privacy First
We don't track you, don't require an account, and don't sell your data. Your sound preferences are stored locally in your browser. Read our Privacy Policy for more details.
