This brownian noise generator builds it on your machine in real time, so it never loops: a smooth brown noise with a little air on top, full enough to fill a room and soft enough to forget. It is made to be deep brown noise for concentration: enough to cover the room, soft enough to fade from your attention. Think of it as an ambient noise generator without recordings — one clean, generated sound instead of rain and birds on a loop. Two knobs shape it: masking widens the wall until nearby voices blur, and stimulation makes it brighter when you need energy, lower when you need calm. 🎨 Brown, pink or white Brown is the default because it is the deepest and warmest. A pink noise generator is one tap away, a step brighter, and white noise for focus is there too — the brightest of the three. Plenty of people swear by white noise for studying, while others find it sharp after an hour. Try each colour and keep the one your ears stop noticing. The light of the panel follows the colour you pick. 🏢 Presets for the room you are in Choose where you are, and the sound is set for you: 1. open office — the widest wall, for voices nearby 2. thin walls — more weight low, for a neighbour or a TV 3. café — lighter, so the hum around you blends in 4. deep reading — quiet and even, for a calm room 5. racing thoughts — more stimulation, when it is loud inside your head 6. too much — softer and quieter, for overloaded days If you came looking for a white noise generator for office chatter, start with open office. It works as simple sound masking for your desk, and you can switch to white noise for work if you like it brighter. Touch any knob and the preset turns into custom. Presets never change your session length. ⏱ A timer that stays out of the way The timer is there when you want it. Drag the dial to 5, 15, 25, 45 or 90 minutes, or press ∞ and let the sound run with no end. The countdown sits quietly inside the dial. When time is up, there is no alarm: the sound brightens and fades over about forty seconds, so you surface instead of jolting awake. Use it as a focus timer for one task, a work timer for the next hour, or a minimalist timer that simply holds the time for you. People who find ordinary countdowns stressful often use it as a gentle adhd timer — it walks you out of focus instead of pulling you out. 🧠 For focus, study and a busy mind People reach for brown noise for studying, brown noise for work and brown noise for adhd — to quiet a noisy room or a noisy head. We make no promises about brains: research is mixed, and no sound works for everyone. What we offer is a good setup — steady background noise for studying, focus sounds that do not shift under you, and a sound you can shape until it helps.
