About CRUX
Enhance your mental well-being with scientifically-designed binaural beats audio therapy.
What are Binaural Beats?
Binaural beats are an auditory illusion created when two slightly different frequencies are played in each ear. Your brain perceives a third tone — the "beat" — equal to the difference between the two. For example, if 200 Hz is played in the left ear and 210 Hz in the right, your brain perceives a 10 Hz beat. Over time, the brain tends to synchronise its own electrical activity toward that frequency, a process known as brainwave entrainment.
CRUX also includes a set of tracks built on a different principle: alternating left-right audio stimulation. Rather than a frequency difference, these tracks pulse a tone rhythmically between the left and right ears at a steady beat. The result is grounding and physically engaging in a way that complements the binaural sessions — a distinct technique for moments when rhythmic bilateral movement is the goal.
Brain Wave Types
- Delta (0.5–4 Hz): Deep sleep and physical restoration
- Theta (4–8 Hz): Meditation, creativity, and the edge of sleep
- Alpha (8–12 Hz): Calm alertness, relaxed focus, and stress reduction
- Beta (13–30 Hz): Active thinking, concentration, and sustained attention
- Gamma (30–100 Hz): High-level cognition, peak focus, and information processing
Benefits
Focus
Quiets mental scatter so you can lock onto one thing at a time. Useful when tasks feel hard to start, concentration keeps slipping, or you need to sustain deep work for longer.
Calm
Eases the low-level tension and restlessness that build through the day. A reliable reset for the moments when your mind won't settle and you need to bring the pressure down.
Sleep
Guides your brain toward the slower rhythms of deep rest. Helpful when you can't switch off at night, when sleep feels shallow, or when you wake in the early hours and struggle to return.
Creativity
Opens up looser, more associative thinking. Good for creative work, brainstorming, or any time you feel mentally stuck and need ideas to start flowing again.
Energy
Lifts mental alertness and physical readiness without caffeine. A useful way to begin a demanding day, push through an afternoon slump, or prepare your mind before something that requires full presence.
Meditation
Deepens and stabilises meditative states, making it easier to stay present and let thoughts pass. Useful for regular practice, or as an anchor when the mind is especially hard to quiet.
Learning
Supports focused absorption of new material. Well-suited to reading, studying, or any session where you want information to settle rather than slip away.
Anxiety Relief
Lowers the background hum of worry and helps regulate an overactive nervous system. Useful during periods of acute stress or as part of a longer-term routine for managing chronic tension.
