Brain Waves - Binaural Beats9.3.5 - Google Play

**With this app, you can easily generate pure tones that help stimulate focus, meditation, or deep relaxation.**

---

**⚠️ Very Important**
• Use headphones for the best sound experience.

• Do not use this app while driving or operating heavy machinery.

• Protect your hearing — high volume is not necessary.

---

**🎛️ Create and Customize Your Own Frequencies**

Easily generate and save your own frequencies using two independent oscillators.
Control them with horizontal sliders, fine-tune with adjustment buttons, or tap the frequency values to input precise numbers (supports two decimal places, e.g., 125.65 Hz).

All sounds are generated **in real-time** — not pre-recorded — allowing uninterrupted playback for as long as you wish.

**🧠 How It Works**

Binaural beats are a perceptual audio illusion that occurs when two slightly different frequencies are played separately in each ear. Your brain interprets the frequency difference as a rhythmic beat, which can influence your mental state.

For example, playing 300 Hz in one ear and 310 Hz in the other creates a perceived beat of 10 Hz — a frequency associated with relaxation or meditation.

For best results, always use headphones at a low to moderate volume. The binaural effect is only noticeable when both ears are engaged.
