Two dials. Live oscilloscope. Pure sine tones. Nothing else.
A minimalist, real-time binaural beat generator written in Python using PyQt6 and sounddevice. Designed for macOS (M4 compatible) — runs on any modern Python 3.9+ system.
- Two dials:
- Carrier Frequency (50–2000 Hz)
- Beat Frequency (0.1–40.0 Hz)
- Live oscilloscope — visual proof the signal is active
- 6 built-in presets
- Mouse wheel control (1 Hz / 0.1 Hz steps)
- Smooth ramp-in/out to avoid pops
- Zero noise, zero ads, zero bloat
No claims of healing, astral projection, or brain rewiring. Just clean, controllable binaural tones.
pip install numpy PyQt6 sounddevicepython3 bbeat.pyThat’s it.
| Name | Beat (Hz) | Brainwave Band |
|---|---|---|
| Deep sleep/Healing | 2.5 | Delta |
| Astral/OBE/RV | 4.0 | Theta |
| Creativity/Calm | 7.0 | Theta |
| Relaxation/Flow | 10.0 | Alpha |
| Focus/Energy | 16.0 | Beta |
| Peak Cognition | 40.0 | Gamma |
- Tired of bloated apps with 10-minute intros
- Wanted instant control over carrier and beat
- Needed visual feedback that audio is live
- Built in one evening. Works.
The CIA declassified "Analysis and Assessment of Gateway Process" (1983) explores binaural beats for altered states.
No endorsement. Just history.
