Ambient Noise Generator

White, pink, and brown noise, plus rain and ocean-wave textures — generated live.

Sound

White, pink, and brown noise are genuine noise-color synthesis. Rain and ocean waves are filtered/modulated noise approximations, not recordings — a reasonably convincing texture for focus or sleep, generated entirely in your browser with no audio files to download.

Synthesized, Not Streamed

Every sound here is generated live using the Web Audio API — real noise-color synthesis for white, pink, and brown noise, and filtered/modulated variations of that same noise for a rain or ocean-wave texture. Nothing is downloaded or streamed, and the engine is shared directly with the Pomodoro Timer's ambient sound feature rather than duplicated.

How to Use This Tool

  1. 1Pick a soundWhite, pink, or brown noise, or a rain/ocean-wave texture.
  2. 2Set the volumeAdjust to a comfortable background level.
  3. 3Press PlayLoops continuously until you stop it.
  4. 4Switch sounds anytimeChanges take effect immediately without needing to restart.

Good to Know

  • White, pink, and brown noise are genuine noise-color synthesis, generated with real, distinct frequency characteristics — not the same sound with a different label.
  • Rain and ocean waves are filtered/modulated noise approximations rather than actual recordings — an honest distinction, since a filtered noise texture is genuinely different from a real environmental recording, even if it sounds reasonably close for background use.
  • This shares its underlying sound-synthesis engine with the Pomodoro Timer's built-in ambient sound option — the same code, reused rather than duplicated.
  • Nothing is downloaded — every sound is generated live using the Web Audio API directly in your browser.

Frequently Asked Questions

What's the difference between white, pink, and brown noise?

White noise has equal energy across all frequencies (a flat "hiss"). Pink noise reduces higher frequencies for a softer sound. Brown noise reduces them even further for a deep, low rumble — many people find brown noise the most soothing of the three.

Is the rain sound a real recording?

No — it's filtered noise shaped to approximate rain's frequency texture, not an actual recording. It's disclosed honestly since a synthesized texture and a real recording are genuinely different things.

Can I use this alongside the Pomodoro Timer?

Yes — they're separate tools, though the Pomodoro Timer also has its own built-in ambient sound option if you'd rather have it in one place during a focus session.

Does this work if I switch to another tab?

Yes — audio keeps playing as long as this browser tab remains open, even if it's not the active tab.
