Learn how the settings work
Beat Frequency: The frequency difference between the two tones that creates the brainwave entrainment effect.
Carrier Frequency: The main tone used as the base signal for generating the binaural beat.
Timer: Sets when the session stops. Online playback supports long sessions, while WAV export is optimized for up to 60 minutes for stability.
What Are Binaural Beats?
Binaural beats are an auditory effect created by playing two slightly different frequencies in each ear (for example, 200 Hz and 210 Hz), resulting in a perceived rhythmic beat (10 Hz) in the brain.
This process is often called brainwave entrainment and may support relaxation, focus, or meditative states, with effects varying between individuals.

Frequently Asked Questions
Answers to common questions about binaural beats and how this generator works.
Do I need headphones for Binaural Beats?
Yes. Headphones are required so each ear receives a slightly different frequency, which creates the binaural effect.
How long should I listen to a session?
Start with 10–15 minutes if you’re new. Many users prefer sessions of 20–30 minutes.
Which frequency should I choose?
Choose based on your goal: Delta for sleep, Theta for relaxation, Alpha for calm focus, and Beta for concentration.
Are these sessions safe?
Generally yes, when used responsibly.
Do not use if you have epilepsy or a history of seizures. If you have a pacemaker, are pregnant, or have a medical condition, consult a medical professional before use.
Avoid listening while driving or operating machinery, as deep relaxation may cause drowsiness.
How is the audio generated?
All sessions are generated in high-quality 44 kHz audio and normalized to safe listening levels. Smooth fade-in and fade-out are applied to ensure a comfortable listening experience.
