Operating manual
Programs
Pick a program and a duration; the engine glides the frequency for you and fades out at the end. Keys 1 to 6 switch sessions.
Focus
Alpha settle, beta build, gamma focus nested in alpha, then cooldown.
Meditate
Alpha, then 7.83 Hz at the edge of theta, then theta, with swelling pulses.
Sleep
Theta, delta, then deepest delta, with gentle drift.
Energize
Reverse wake-up: delta, theta, alpha, beta.
Free Play
Pick a rate and a rhythm right under the session cards; it runs until you stop it.
Some program stages nest fast pulses inside a swell at your alpha rate, or let the rate wander by about 1% so the brain keeps tracking on long sessions. Both happen on their own.
Asset
Composed alertness for work, games and training. It doesn't hand you anyone's abilities; it helps you settle into calm, sharp focus faster and hold it longer.
Composure
Three minutes at your alpha with slow breathing and a few cyclic sighs: two breaths in through the nose, then one long breath out. With a soundscape on, the breath bar in the player shows you when. The same one-minute reset comes back every 25 minutes.
The session
A climb through beta to a 40 Hz sharpening, then sustained 18 Hz beta in 5-minute blocks, each followed by a one-minute gamma burst so the rhythm keeps changing. Every 25 minutes, a one-minute reset at your alpha with slow breathing, because short breaks sustain attention. A two-minute cooldown at the end. Never while driving; outdoors, keep one ear open.
Soundscapes
Ten choices under Sound. The sea, the cicadas, the rain, the heartbeat and the singing bowl breathe with you, and the metronome counts your breath; the tape room and pink and brown noise are steady beds, good for masking, that still carry the pulse.
Heartbeat
A slow, resting heartbeat, the familiar lub-dub, low and round, as you hear it from inside with your ears covered. It follows the breath the way a real heart does: a little faster on every in-breath and a little slower on every out-breath, about 66 beats a minute at the top of the breath and 54 at the bottom. That swing is called respiratory sinus arrhythmia, and breathing at about six breaths a minute is what makes it largest; it is the point of resonant breathing. So the heartbeat plays what your breathing is meant to bring about. It leaves the beat to the tones, so the Pulse setting doesn't apply. It lives in the low bass: headphones, not laptop speakers.
Singing bowl
A large bowl, struck with a felt mallet at the start of every in-breath and more softly at the start of every out-breath, singing through the breath between. Its four tones sit at the uneven ratios a real bowl has, each fading at its own pace. A real bowl shimmers because each tone is really two, a hair apart in pitch, beating against each other; here each beats at its own slow rate, a little differently in each ear, so the sound turns slowly. With the pulse on and a beat in theta or delta (up to 8 Hz), the deepest tone's shimmer takes the beat's rate and swells on every pulse, as deeply as the Pulse setting asks. A natural match for Meditate and Sleep.
Tape room
The room the file's recordings were played back in: a reel-to-reel machine running blank tape. The hiss of each track, its own in each ear; a faint 60 Hz hum from the amplifier, wavering with the capstan's wow and flutter; the low rumble of the room; and now and then a brief dropout that softens the hiss, as worn tape does. A steady bed like pink noise, with more character. It carries the pulse in its hiss. Good for Asset.
Metronome
A wooden tick, once a second, counting the breath: four ticks in and six out at the resonant pace, locked to the breath bar. In-breath ticks are a brighter tick, out-breath ticks a darker tock, and the first of each is a little louder, so you can follow the turn of the breath with your eyes closed. It sits in a small room, a little different in each ear, and drifts slightly over minutes when the sound is set to change. It leaves the beat to the tones, so the Pulse setting doesn't apply. Steady enough to work to, and a good match for anyone who likes to count.
Rain
Steady rain modelled on a field recording: a bright, even hiss with its own balance of lows and highs and stereo width, and drops landing at the recording's rate, about 18 a second standing clear of the hiss and one a second sharply. It gusts gently with your breath. With the pulse on, the hiss carries the beat in its middle range and drops land a little more often on each pulse. A good match for Asset: steady enough to work in, textured enough to stay interesting.
Summer cicadas
A chorus modelled on a field recording of cicadas: two species clicking about 76 and 180 times a second, each click ringing near 8 kHz, calls that climb with your in-breath and fade through the out-breath. With the pulse on, they chirp in time with slower beats, and at gamma the slow species locks its own clicks to the beat, two per beat. A good match for Focus.
The sea
Surf that rolls in as you breathe in and draws back as you breathe out. It is modelled on a real surf recording, measured in nine frequency bands: each breath borrows the shape of one of eight real waves, stretched to fit your breathing, with the recording's own balance of lows, mids and highs and its stereo width. No two breaths in a row get the same wave. Close your eyes and let your breathing follow it. It works with every session, and a small breath bar in the player shows the same rhythm.
Paces
Resonant (4 in, 6 out) is about six breaths a minute, the slow-breathing rate most studied for calm. Slow (4 in, 7 out) suits sleep. Easy (4 in, 4 out) is a gentler start. Changing pace keeps your place in the breath.
Breathing figure
The dust on Fig. 1 follows the same breath: it gathers in toward the head as you breathe in and drifts back out as you breathe out, circling slowly, a little faster in the higher brainwave bands. It moves but never flickers. Switch it in the player; it stays still if your device asks for reduced motion.
Making it land
The settings that strengthen entrainment, and why:
Carrier tuned to the rate
The brain responds more strongly to pulsed tones of a few hundred hertz than to very low ones, especially at fast rates, so the pitch rises with the beat: about 160 Hz for deep delta, 320 Hz for alpha, 490 Hz for gamma. It's trimmed so it doesn't get louder. Prefer a darker sound? Choose Low and soft under Fine-tuning.
Pulse
The ocean and the noise bed carry the beat as well, in their 1-4 kHz range, where hearing is most sensitive. A broad sound reaches far more of the ear than a single tone, and keeping the low rumble smooth avoids roughness at fast rates. 0% leaves the sea untouched.
A sound that changes
Over minutes, the sea drifts brighter or darker, calmer or livelier, wider or narrower. The brain tunes out sound that never changes; a slowly changing one keeps it listening. Switch it off when you want a fixed sound, such as when comparing settings.
Your alpha
Alpha stages use your own alpha rate. Natural alpha varies from about 8 to 12 Hz between people, and rhythms take most easily near where the brain already sits.
Sharp pulses where it counts
Focus and Energize finish on isochronic pulses, the strongest driver. Binaural beats are the weakest, and fade above about 30 Hz. Sleep and Meditate use soft, rounded pulses on purpose, because comfort matters more than strength when you're trying to let go.
You
Closed eyes, headphones, a quiet dim room and at least 15 minutes help as much as any setting. So does paying attention to the sound.
Brainwave frequencies
Gamma (40 Hz)
High-level information processing and peak concentration.
Beta (20 Hz)
Alert consciousness and focused attention.
Alpha (10 Hz)
Relaxed alertness, creativity, and flow states.
7.83 Hz
The edge between alpha and theta, a gentle bridge into meditation.
Theta (6 Hz)
Deep relaxation, meditation, and memory consolidation.
Delta (3 / 1 Hz)
Deep, dreamless sleep and physical restoration.
Rhythms
Isochronic
Strongest cortical driving. Sharp on/off pulses.
Pulse
Clean rhythmic amplitude modulation.
Swelling
Pulses that rise and fall in strength, easier on long sessions.
Binaural

How to use
Headphones for anything involving binaural or hybrid. Start at low master volume and let the session run; the fade-out at the end is automatic. Space bar plays and stops.
Safety
Caution. Do not use if prone to seizures. Do not drive while listening. This is a wellbeing tool, not a medical device.
