White Noise
Constant power across all frequencies. Ideal for masking distracting speech.
FREQUENCY: HIGH
Alpha Waves
A 10 Hz beat — relaxed and alert at the same time, and the best place to start.

Sound Library
Calibrated frequencies for deep work and relaxation.
Color Noises
Continuous frequencies for auditory masking.
Brown Noise
Deep, bass-heavy rumble reminiscent of a distant waterfall or thunder.
FREQUENCY: LOW
Pink Noise
Balanced spectrum that sounds more natural to the human ear, like steady rain.
FREQUENCY: BALANCED
Red Noise
Even deeper than Brown noise, focusing heavily on the low-end spectrum.
FREQUENCY: LOW
Black Noise
Near-silence with subtle low-frequency drift. Meditative, like the sound of a quiet room at night.

The best-documented rhythm in EEG
Alpha, about 8 to 13 Hz, was the first brain rhythm ever recorded — Hans Berger identified it in 1924, and the prominent 10 Hz oscillation that appears when a relaxed subject closes their eyes is still one of the most robust findings in electrophysiology.
It marks a specific state: awake, calm, not actively processing visual input. Not drowsy, not effortful. This preset sits at a 10 Hz offset, in the middle of that band.
Why it is the default here
Alpha is the preset to try first, for two practical reasons. At 10 Hz the beat is fast enough to blend into a texture rather than register as separate pulses, which means it fades into the background the way a working layer should. And the state it is named for — settled but switched on — is the one most people are actually aiming for at a desk.
It is also the least likely of the four to work against you. Delta and theta pull towards drowsiness; beta can feel like pressure on a bad day. Alpha rarely does either.
A working stack
The combination that most people converge on: brown noise at a moderate level for masking, an alpha beat underneath at low volume, and a 25- or 50-minute timer running. The noise handles the room, the beat gives the session a constant, and the timer handles the clock-watching.
Start the binaural volume low and leave it there. If you are consciously listening to the tones, they are too loud to be doing the job they are meant to do.
Common questions
Which binaural preset should I start with?
Alpha. At 10 Hz it blends into the background rather than pulsing, and the relaxed-but-alert state it is named for is what most people want while working. Try beta if you need more edge and theta if you want to loosen up.
Can I layer alpha under rain or noise?
Yes — that is the intended use. Colour noise, one ambient recording and one binaural preset can play together with independent volume sliders. Brown noise with alpha underneath is the most common stack here.
Do I really need headphones?
Yes, for any binaural preset. Through speakers the two tones mix in the air before they reach your ears and the effect is lost entirely.
