Binaural Beats.
Create precise binaural beats right in your browser — with background sounds, frequency control, and export to MP3 or WAV. No installation needed.
Everything you need
Precise frequency control
Control left and right frequencies in steps of 0.1 Hz. Glide smoothly between frequencies with the glide effect.
25+ background sounds
Rain, waves, forest sounds, meditation chants, and more — or upload your own audio files.
Export right in the app
Render your session as MP3, 16-bit, or 32-bit WAV — completely local, no server, no waiting.
Save presets
Use predefined brainwave presets (Delta, Theta, Alpha, Beta, Gamma) or save your own configurations.
What are binaural beats?
When two slightly different tones — one per ear — are played simultaneously, the brain perceives a third, pulsating tone. This perception synchronizes brain activity with the difference frequency and can specifically promote various mental states.
For best results: use headphones.
Deep sleep
Delta waves promote deep sleep and physical recovery. Ideal for falling asleep or daytime naps.
Meditation & creativity
Theta waves occur during deep meditation and light sleep. They promote creativity, intuition, and emotional processing.
Relaxation & flow
Alpha waves arise during calm wakefulness and light relaxation. Perfect for stress relief and relaxed focus.
Focus & concentration
Beta waves dominate during active concentration and mental engagement. They support learning, problem-solving, and productivity.
Peak concentration
Gamma waves are associated with intense information processing and peak performance. They promote clarity and cognitive performance.
Why do binaural beats work?
The effect is not imaginary — it's based on measurable neural processes.
Two tones, one effect
Binaural beats are created exclusively in the brain. When the left ear hears a tone at 200 Hz and the right ear one at 210 Hz, the brain perceives a beat of 10 Hz — even though this tone doesn't exist in reality. Prerequisite: headphones, so both tones arrive strictly separated.
Frequency following response (entrainment)
The brain tends to align its own electrical activity with external rhythmic stimuli. This mechanism is called the "Frequency Following Response." A perceived beat of 10 Hz can cause brainwaves to synchronize in the alpha range (relaxation, calm wakefulness).
Interaction with the meditative state
During meditation, brain activity typically slows from beta (everyday thinking) through alpha (relaxed wakefulness) to theta (deep meditation). Binaural beats can support this transition by providing the brain with a rhythmic "target" — similar to a metronome for neural oscillation.
Auditory cortex and attention
The processing of binaural beats takes place in the auditory cortex — the area that evaluates sounds. At the same time, the listening experience influences the limbic system, which is responsible for emotions and stress response. This explains why regular listening can have measurable effects on cortisol (stress hormone) and overall well-being.
What the research says
Studies show evidence of reduced anxiety, improved attention, and deeper relaxation. Effects vary individually and depend on factors such as volume, listening duration, and baseline state. Binaural beats are not a substitute for medical treatment, but an effective tool for mental support.
