Welcome to your User Manual. We hope that your first steps into the world of using frequency to improve your health will be pain-free (pun intended). Since the beginning of time the human race has used tones, bells, music, and all sorts of frequencies to make themselves feel better. Most people feel the exhileration of listening to their favourite genres of music, and we feel the passion, sadness and jubilation that drives the experience of a great movie.

If you've felt that, then there should be no hesitation understanding that frequency drives our mood, and our mood drives our whole day-to-day experience. Put simply, there is a subliminal reaction in our bodies to all kinds of frequency, whether that is sound, light, or others we are still not yet fully aware for.

For those that we are aware of, now is your time to harness them using Binaural Beats Studio. I'll try to make this the best experience possible during your journey.

Introduction

What is Binaural Beats Studio?

Binaural Beats Studio is a powerful audio therapy app that generates precise frequencies to help you:
- Focus - Enhance concentration and study performance
- Relax - Reduce stress and anxiety
- Sleep - Improve sleep quality and duration
- Meditate - Deepen meditation practices
- Energize - Boost motivation and alertness
- Heal - Support wellness and recovery

How It Works

The app uses four types of audio technology:
1. Binaural Beats - Different frequencies in each ear create a perceived third frequency
2. Isochronic Tones - Evenly spaced pulses of sound
3. Solfeggio Frequencies - Ancient healing tones
4. Colored Noise - Different spectral distributions of noise

Requirements

- Android: 7.0 (Nougat) or higher
- Storage: ~50 MB
- Headphones: Required for binaural beats (recommended for all modes)
- Internet: Only needed for purchases and donations

Understanding Audio Modes

Binaural Beats

What: Two slightly different frequencies (one in each ear) create a perceived third frequency.

How: If left ear = 300 Hz and right ear = 310 Hz, your brain perceives 10 Hz (the difference).

Requirements: Must use headphones/earbuds.

Best For: Focus, meditation, sleep, cognitive enhancement

Example: Deep Focus preset (300 Hz + 320 Hz = 20 Hz beta waves)

Isochronic Tones

What: Single tone that pulses on and off at regular intervals.

How: The tone itself alternates, creating rhythmic patterns.

Requirements: Can use speakers or headphones.

Best For: Alertness, concentration, rhythmic entrainment

Example: 10 Hz alpha frequency with 50% duty cycle

Solfeggio Frequencies

What: Ancient musical scale with specific healing properties.

Frequencies:

- Pink Noise - Lower frequencies emphasized (like rain)

PREMIUM:
- Brown Noise - Even lower frequencies (like waterfall)
- Red Noise - Deepest frequencies (like distant thunder)
- Green Noise - Mid-frequency emphasis (nature ambient)
- Blue Noise - Higher frequencies (like hissing)
- Violet Noise - Highest frequencies (like wind)
