Full walkthrough of every sound generator, layer behaviors, presets, sleep timer, and shareable mixes — plus when to reach for each one.
How to use
- Start with Deep Focus Rain or Cafe Work — both are tuned to sit under thinking without pulling attention.
- Drop any layer's volume if it breaks your focus — a common fix is lowering rain to 0.45 and pink noise to 0.25.
- Use the sleep timer as a focus timer — 30 or 60 minutes makes an easy Pomodoro-style block.
- Save mixes for different focus modes (coding, writing, reading) so they load in one tap later.
FAQ
Why noise for focus instead of music?
Lyrics and melody compete with language and reasoning in your brain. Broadband noise and non-intrusive ambience mask distractions without engaging the same circuits, so focus holds longer.
Pink, brown, or white noise for deep work?
Pink noise is the most popular for multi-hour focus — it's balanced and the least fatiguing. White is brighter and better for short bursts. Brown is warmer and closer to sleep territory.
Does the coffee-shop loop sound repetitive?
Layer it with light rain or a pink noise bed. The rain randomness hides the loop point and keeps the mix feeling fresh across long sessions.

What you can shape with this engine
- Noise generation — white, pink, and brown noise beds for masking
- Nature and ambience — rain, ocean, forest, fire, thunder, wind, and more
- Layered playback — loop steady beds, fire events on an interval, or rare sounds on random delays for realism
- Presets and sharing — Quick Presets, sleep timer with fade-out, and Share links that restore a mix
Common use cases
- Focus and relaxation — steady masking that hides unpredictable noise
- Sleep — a stable audio floor so small sounds are less likely to wake you
- Learning and experimentation — hear how different layers and levels behave over time

Focus is mostly about masking
Deep work breaks when the brain notices a sudden sound — a door, a
keyboard, a voice. The job of a focus mix isn't to entertain you; it's to
raise the floor so sudden events blend in.
That's why the most effective focus mixes are flat and broadband: rain,
pink or brown noise, or coffee-shop ambience. They mask the highs and
mids where most distractions live.
Good starting mixes
- Deep Focus Rain — rain 0.55 + pink noise 0.3 + soft fan 0.3.
- Cafe Work — coffee-shop ambience 0.6 + rain 0.3.
- White Noise Focus — white noise alone at 0.5, then reduce if bright.
