Noiseloop

Noiseloop is a free ambient sound mixer that helps you create a calm listening environment for focus, studying, reading, and deep work. Open it in your browser and build a mix without creating an account or installing an app. Layer 16 sounds, including rain, forest ambience, campfire, flowing water, ocean waves, and white, brown, or pink noise. Adjust each sound independently and use the master volume to control the whole mix. For a quick start, choose Noise Blocker, Deep Work, Relax, or Light Work, then browse the sound combinations within that mode. Use the built-in session timer for 25, 45, 60, or 90 minutes. A chime marks the end of your session, with optional browser notifications and a countdown in the browser tab. The simple, ad-free interface is designed for desktop and laptop work.
