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.
