Brain Waves - Binaural Beats

**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. 🔗 Learn more: [Binaural Beats – Wikipedia](https://en.wikipedia.org/wiki/Binaural_beats) --- **🎧 Audio Tips** • Use headphones for a proper binaural experience. • The app’s volume slider is separate from your device’s system volume — adjust both if needed. • High volume is not required for effective results. --- **⚙️ Android Compatibility Note** Newer Android versions may limit background processes to save battery and optimize performance.
