Binaural beats are an auditory illusion created when two slightly different frequencies are played separately into each ear. Your brain perceives the difference as a rhythmic beat, which can influence brainwave patterns through a process called entrainment. This free online generator uses your browser's Web Audio API to create precise binaural beats without any external audio files. Use stereo headphones for the best effect — the beat frequency is only perceived when each ear receives a different tone.
