Deep SleepBinaural Beats
Your Brain Can Be Guided Into Any State. From Deep Sleep to Laser Focus.
No pre-recorded MP3s. No compressed YouTube frequencies. SINE generates binaural beats in real-time at 44,100 samples per second with 0.01 Hz precision. And bio-resonance shows you what's actually changing in your body.

The Problem
Most 'frequency music' is fake.
You're Not Hearing Real Frequencies
Most '528 Hz' videos on YouTube were never at 528 Hz. MP3 compression, export, and re-encoding destroy the waveform. What's labeled as a frequency is just marketing.
Every App Feels the Same
Fixed presets, no customization, no control. You can't set your own frequency, can't layer sounds, can't program a journey.
No Proof It's Working
You meditate for 30 minutes and just hope something is happening. No data, no feedback, no way to know if the frequency is actually affecting your nervous system.

Brainwaves
5 States. You Choose.
Two slightly different tones, one in each ear, create a third tone inside your brain. That tone can guide your brainwaves into specific states.
0.5–4 HzDeltaDeep Sleep & Healing
The slowest brainwaves. Your body repairs itself, growth hormone is released, immune system regenerates. A Harvard study showed: delta binaural beats before sleep measurably increased slow-wave sleep phase.
4–8 HzThetaDeep Meditation & Creativity
The state between waking and sleeping. This is where creative insights and deep meditation happen. A 2023 study showed: theta binaural beats achieved 18% higher HRV improvement than silent meditation.
8–13 HzAlphaRelaxation & Calm Focus
The 'flow state.' Relaxed yet alert. A 2019 systematic review of 22 studies found consistent anxiety-reducing effects with theta/alpha binaural beats, especially before stressful events.
13–30 HzBetaConcentration & Problem-Solving
Active thinking and focus. A 2023 meta-analysis found small but significant improvements in sustained attention tasks with beta-range binaural beats (13-30 Hz).
30–100 HzGammaPeak Performance & Insight
The fastest brainwaves. Linked to peak cognitive processing, creativity, and the 'aha moment.' Experienced meditators show significantly more gamma activity.
The Research
What Science Says
Binaural beats aren't a trend. They're a well-researched field of neuroscience.
22 Studies
Psychological Research, 2019
Systematic review found consistent anxiety-reducing effects with theta-frequency binaural beats before stressful events.
+18% HRV
Applied Psychophysiology, 2023
Theta binaural beats group showed 18% higher resting HRV improvement compared to silent meditation alone.
3–5 Min
Psychophysiology, 2023
Real-time HRV monitoring showed: parasympathetic shift begins within 3-5 minutes of practice onset.

What Practitioners Are Saying
As someone with ADHD, I've tried dozens of apps. SINE is the only one where I can truly customize my frequencies. Bio-tracking shows me what works.

Bio-ResonanceUse Cases
The Right Frequency for Every Goal
😴
Deep Sleep
Delta 2 Hz + Brown Noise
Guide your brain into the deepest sleep phases. Combine delta binaural beats with warm brown noise for the ultimate sleep environment.
🎯
Laser Focus
Beta 18 Hz + Pink Noise
Block distractions and activate concentrated thinking. Beta waves with pink noise create the perfect work environment.
🧘
Deep Meditation
Theta 6 Hz + 528 Hz
Reach meditative states that normally take years of practice. Theta binaural beats on a 528 Hz base, the most researched frequency.
💆
Stress Relief
Alpha 10 Hz + Ocean
Activate your parasympathetic system in minutes. Alpha waves calm the nervous system. The 2019 review found consistent anxiety reduction.
FAQ
Frequently Asked Questions
Do binaural beats actually work?
Yes, and the research is getting stronger. A systematic review of 22 studies (2019) found consistent anxiety-reducing effects. A 2023 study showed 18% higher HRV improvement with theta binaural beats vs. silent meditation. But SINE goes further: bio-resonance tracking lets you measure the effect on your own body. No faith required.
Do I need headphones?
Yes, that's the physics. Binaural beats work by playing a slightly different tone in each ear. Your brain creates the difference as a third tone. Any stereo headphones work, expensive ones aren't necessary.
How long should I listen?
Research shows: your brain needs at least 10-15 minutes to synchronize. 20-30 minutes is optimal for deeper states. Some listen overnight for sleep. SINE's bio-resonance shows you the changes in real-time, so you see exactly when the effect kicks in.
Are binaural beats safe?
Yes, for the vast majority of people. They are non-invasive with no known side effects. People with epilepsy should consult a doctor first. Don't listen while driving or during activities requiring full attention.
What makes SINE different from other apps?
Three things: (1) Real-time synthesis instead of pre-recorded files with 0.01 Hz precision. (2) You CREATE your own frequencies in the Creator instead of just playing presets. (3) Bio-resonance tracking measures the effect on your body with HRV and heart rate. No other provider combines all three.
What's the best frequency for sleep / focus / anxiety?
Sleep: Delta 0.5-4 Hz (especially 2-3 Hz) with base 100-150 Hz. Focus: Beta 14-20 Hz with base 200-400 Hz. Anxiety: Alpha 8-13 Hz or Theta 4-8 Hz. But: every brain is different. That's why SINE lets you set any frequency precisely, and bio-resonance shows you what works for YOU.
