HemiSync

HemiSync generates binaural beats by playing slightly different frequencies in each ear. Your brain perceives the difference as a rhythmic "beat" that can help guide your mental state.

FEATURES
• Independent left and right ear frequency control
• Four waveform types: Sine, Square, Triangle, and Sawtooth
• Built-in presets for common brainwave states
• Create and save your own custom presets
• Session timer with auto-stop
• Real-time beat frequency display
• Smooth volume fading

BRAINWAVE CATEGORIES
• Delta (0.5–4 Hz): Deep sleep and healing
• Theta (4–8 Hz): Meditation and creativity
• Alpha (8–14 Hz): Relaxation and calm focus
• Beta (14–30 Hz): Focus and concentration
• Gamma (30–100 Hz): Peak awareness and insight

HOW IT WORKS
Set different frequencies for each ear — for example, 200 Hz in the left ear and 210 Hz in the right ear creates a 10 Hz Alpha binaural beat. Use headphones for the best experience.

HemiSync is free, open-source, and contains no ads or tracking.
