Binaural Beat app for Android description
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 projects CREDITS for full attribution.
Note: binaural beats are not a medical treatment. This app is for relaxation and personal experimentation only.
