Binaural Beat Generator
Generate binaural beats at specific frequencies for meditation, focus, and brainwave entrainment. Use with headphones for best results. Adjustable base frequency and beat frequency.
Complete Guide: Binaural Beat Generator
Everything you need to know about using this tool effectively
The Binaural Beat Generator creates audio tracks that play slightly different frequencies in each ear. Your brain perceives the difference between these two tones as a rhythmic beat, which is the basis of brainwave entrainment. Set your target frequency, generate the audio, and listen with headphones. All processing happens locally in your browser.
This tool generates two sine wave tones at slightly different frequencies using the Web Audio API - one for each ear. Your brain perceives the difference between the two frequencies as a rhythmic pulsing beat, which is the basis of brainwave entrainment.
Meditation and Mindfulness Practice
Generate theta-range binaural beats (4–8 Hz) to support deep meditation sessions. Many meditators use these tones as an anchor to settle into a calm, focused state.
Concentration and Study Sessions
Beta-range beats (12–30 Hz) are commonly used to support alertness and focus during study, writing, or any task that requires sustained attention.
Sleep and Relaxation
Delta-range beats (1–4 Hz) are associated with deep sleep stages. Listening before bed may help create a calming pre-sleep routine.
Stress Reduction
Alpha-range beats (8–12 Hz) correspond to relaxed, wakeful states. Use them during breaks or at the end of a workday to decompress.
Creative Work
Some musicians, writers, and designers listen to theta or alpha beats while working on creative projects, finding that the ambient tones help maintain a flow state.
Yoga and Breathwork
Pair binaural beats with yoga or breathing exercises to maintain a steady rhythm and deepen the practice. The consistent tone provides an unobtrusive background.
Put On Headphones
Binaural beats only work when each ear receives a separate frequency. Use headphones or earbuds - speakers mix the channels together and cancel the effect.
Set the Beat Frequency
Choose the difference frequency that corresponds to your goal. Delta (1–4 Hz) for sleep, theta (4–8 Hz) for meditation, alpha (8–12 Hz) for relaxation, beta (12–30 Hz) for focus.
Set the Base Frequency
The base frequency determines the overall pitch of the tone you hear. A common starting point is around 200–400 Hz, which is comfortable for extended listening.
Choose Duration
Set how long the binaural beat track should last. Longer sessions (10–30 minutes) give your brain more time to respond to the frequency.
Generate and Listen
Click generate to create the audio. Play it back and adjust the volume to a comfortable level - binaural beats should be heard softly, not loudly.
Download the Audio
Save the generated track as a WAV file so you can listen offline, load it onto your phone, or add it to a meditation playlist.
Keep the volume low - binaural beats work best at a quiet, comfortable level and loud listening can cause fatigue
Start with 10–15 minute sessions if you are new to binaural beats and gradually increase the duration
Experiment with different beat frequencies within your target range to find what feels most effective for you
Use binaural beats as part of a consistent daily routine for meditation, study, or sleep for best results
Layer binaural beats under nature sounds or soft music using an audio merger - the effect works as long as headphones deliver separate channels
Stay in the 150–400 Hz range for the base frequency since higher values can feel piercing over long sessions
Do binaural beats actually work?
Research on binaural beats is mixed but growing. Some studies show measurable effects on relaxation and focus, while others suggest the benefit may come from the calming ritual itself. Many people find them genuinely helpful regardless of the mechanism.
Why do I need headphones?
Binaural beats rely on each ear hearing a slightly different frequency. When played through speakers, the two tones mix in the air and the binaural effect is lost. Headphones or earbuds are required.
What beat frequency should I use for focus?
Beta frequencies between 12 and 30 Hz are associated with alertness and concentration. A beat frequency of 14–18 Hz is a popular starting point for study and focused work.
Are binaural beats safe?
For most people, yes. However, people with epilepsy or seizure disorders should consult a doctor before using any form of brainwave entrainment, as rhythmic auditory stimulation may trigger episodes in sensitive individuals.
Is my audio processed on a server?
No. The binaural beat is generated entirely in your browser using the Web Audio API. Nothing is uploaded or sent to a server. Your session is completely private.
Can I use the generated audio commercially?
Yes. The audio is generated mathematically on your device. There are no copyright restrictions on the output, so you can use it in apps, videos, meditation guides, or any other project.
