Binaural Beat

Binaural beat generator with the classic SBaGen engine and ambient backgrounds
New in version 1.1
- Added a custom app icon (stylistic brain with sine waves)
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.
