Unlimited Noise

Mix live sound for sleep and focus.

Mac iPhone iPad

Mix noise colors, nature, machines, and generative music for sleep, focus, or calm. Each channel is synthesized live, without recordings, loop seams, or sound packs to download.

Every sound, zero recordings

• White, pink, brown, blue, violet, gray, and black noise, each with a distinct tonal character.
• Rain, ocean, wind, streams, thunder, birds, crickets, frogs, and other changing natural scenes.
• Fireplace, fan, train, café, purring cat, heartbeat, wind chimes, singing bowls, and other cozy or resonant sounds.
• Binaural beats — pick your beat and carrier frequency for focus or sleep (headphones required, gently level-capped for hearing safety).

Music that composes itself

Generative channels range from sparse piano, pads, bells, and woodwinds to lofi, synthwave, house, and drum & bass. A shared chord cycle keeps layered channels in harmony.

Highlights

• Shape every layer — adjust volume and character controls such as rain intensity, wave period, thunder frequency, heartbeat BPM, and music tempo.
• Start from a preset — choose a scene such as Deep Sleep, Rainy Cabin, Lofi Study, or Night Drive, then make it your own.
• A gentle finish — set the radial sleep timer and let the mix fade out instead of cutting off.
• Small by design — synthesized audio avoids large downloadable sound packs, so the app starts instantly.
• No seam to learn — a recording repeats and your ear finds the loop. Synthesized sound has no loop to find, so it stays invisible for hours. Your ears know a loop when they hear one; this never gives them the chance.
