Create custom brainwave entrainment audio for sleep, focus & meditation
What we do
Binaural beats only work with stereo headphones. The "beat" is an illusion created inside your brain when left and right ears hear slightly different frequencies.
Unlike basic generators, our Dual Mixer lets you balance the raw frequency tones with soothing background noise (Pink/Brown). For deep sleep, keep the tones quiet and the noise louder.
Set the Sleep Timer to automatically fade out the audio after 15, 30, or 60 minutes. Or, download the high-quality WAV file to listen offline on your phone.
Use our scientifically tuned presets for Delta (Deep Sleep) and Theta (Meditation). We also include the Schumann Resonance (7.83Hz) for grounding.
Switch to the Gamma (40Hz) or Beta preset when you need intense concentration or problem-solving capability. Perfect for study sessions.
This tool runs entirely in your browser using the Web Audio API. No audio data is uploaded to our servers, ensuring your usage is private and fast.
