About Focus & Sleep Sound Mixer
The Focus & Sleep Sound Mixer lets you create your own ambient soundscape by blending rain, ocean, wind, fire, and white noise together. Mix exactly what your ears need — whether that's layered nature sounds for studying, brown noise for deep focus, or a gentle rain track for sleep. It's completely free, runs right in your browser, and requires no signup or account.
Every sound is synthesized live as you adjust the sliders, giving you precise control over your ambient noise mixer. Create your perfect study music or sleep environment by tweaking each sound layer in real time. Your audio settings stay on your device — nothing is uploaded or stored anywhere else, so you get complete privacy while mixing your focus sounds.
The built-in sleep timer lets you fade out gradually, perfect for drifting off without silence suddenly breaking the spell. Set it and let the ambient sounds gently diminish over your chosen time, whether you're using rain sounds to mask noise, white noise for deep sleep, or a combination of nature sounds for relaxation. Adjust, save, and use your custom noise generator mix again whenever you need it.
