Binaural Beat

Binaural Beat is a binaural beat generator for relaxation, focus and sleep.

A binaural beat is created by playing two slightly different frequencies, one

in each ear. The brain perceives a third "beat" at the difference between them.

Use headphones for the effect to work.

Features:

* Two audio engines:

- Simple: a lightweight built-in tone generator with base and beat frequency

sliders.

- SBaGen: the classic Sequenced Binaural Beat Generator by Jim Peters, with

58 bundled preset sequences (brainwave states, focus levels, chakra

progressions and more).

* Independent background layer that mixes under the beats, with its own volume:

- Pink and brown noise, generated on the fly.

- Looping nature samples (river, train).

* Clean, modern interface.

This is a 2026 revival of an old project: the original was a native Android

port of SBaGen via OpenSL ES. This version keeps the genuine SBaGen engine but

runs it on a modern stack.

Binaural Beat is free software, released under the GNU GPL v2. It builds on

SBaGen by Jim Peters (GPLv2). Bundled audio samples are freely licensed

(Creative Commons); see the project's CREDITS for full attribution.

Note: binaural beats are not a medical treatment. This app is for relaxation

and personal experimentation only.
