Unlimited Noise gives you a whole library of sleep, focus, and calm sounds, and not one of them is a recording. Every sound is synthesized live, from scratch, the moment you press play. There are no loops and no seams, so you will never catch yourself thinking you have heard that seagull before. Rain never falls the same way twice, thunder never repeats, and the music composes itself forever. Every sound, zero recordings. The full noise spectrum includes white, pink, brown, blue, violet, grey, and black noise, each with its own character, from bright hiss to near silence with sparse soft murmurs. Nature sounds come alive with rain, ocean waves, wind, stream, waterfall, thunder, birds, crickets, a night pond of frogs and owls, and rain drumming on a tent. Cozy and mechanical sounds include a crackling fireplace, fan, train, washing machine, boat cabin, café murmur, a purring cat, and a resting heartbeat. Resonant and rare sounds include wind chimes, singing bowls, a music box, an aeolian harp, a wordless choir, and whale song. Binaural beats let you pick your beat and carrier frequency for focus or sleep, with headphones required and levels gently capped for hearing safety. Music that composes itself. The generative music channels play endlessly and never repeat, including sparse piano, breathing ethereal pads, FM bells with dying echoes, solo woodwinds, and brass swells, plus beat driven genres from lofi and synthwave to techno, trance, house, drum and bass, and electro swing. They all draw from one shared chord cycle, so any combination you layer stays in harmony. Mix it your way. Layer any sounds together with per sound volume and a master fader. Shape each sound's character, including rain intensity, wave period, gust depth, thunder frequency, heartbeat BPM, and music tempo. Curated presets like Deep Sleep, Thunderstorm, Rainy Cabin, Ocean Escape, Lofi Study, and Night Drive get you there in one tap. Your mix is remembered exactly as you left it, ready the next time you open the app. Why you will love it. There is no loop to notice. Recordings repeat and your brain learns the seam, but synthesized sound has no seam to learn, so it stays invisible for hours. It falls asleep with you. Drag the radial sleep timer up to two hours and the mix fades out gently instead of cutting off. The real time safe engine keeps every layer glitch free no matter how many sounds you pile on. Every sound is synthesized, so there are no gigabytes of sound packs to download and the app starts instantly. The same sounds, presets, and saved mix feel at home on the Mac, iPhone, and iPad. One purchase, every device. Buy once and get both the Mac and the iPhone or iPad apps. There is no account, no subscription, no in app purchases, and no cloud required. Your ears know a loop when they hear one. Unlimited Noise never gives them the chance.
