White Noise for Focus
White noise contains all audible frequencies at equal intensity, creating a consistent sound blanket that masks sudden noises and helps maintain concentration. Research from acoustic engineering shows that steady-state broadband sound can reduce the perceived impact of intermittent noise distractions.
Our player generates a smooth ambient loop that pairs with six canvas-based visual themes. Each theme creates a different atmospheric backdrop while you work, study, or relax.
Breathing Rhythm Timer
The breathing rhythm timer offers four patterns designed for different scenarios:
- 4-7-8 Pattern — A slow, asymmetric rhythm often used before sleep or during breaks.
- Box Breathing — Equal-duration phases (4-4-4-4) used for steady focus.
- Relax Pattern — Extended exhale (4-0-6-0) for winding down.
- Energy Pattern — Quick cycles (3-0-3-0) for a brief reset between tasks.
The animated circle and SVG progress ring provide visual feedback to help you maintain the rhythm without counting.
Built-In Productivity Timer
Set preset durations (10, 25, or 50 minutes) or enter a custom time. The countdown appears in both the timer display and the browser tab title, so you can track progress even when the tab is in the background. When the timer ends, an audio alert plays to bring your attention back.
Works Everywhere
WhiteNoise.top is a lightweight static site that runs entirely in your browser. It works on desktop, tablet, and mobile devices with no installation required. All audio is generated or played client-side, so there is no server load and no latency.
