Most ambient audio tools loop compressed, static MP3 files in bloated Electron wrappers. Anahat (Sanskrit: अन​ाहत — "The Unstruck Sound") generates 100% of its audio in real-time using pure mathematical synthesis. It pairs a dual-channel binaural engine with 11 GPU-accelerated WebGL visualizer engines that react to sound. Route audio directly from browser, or sync your breathing to autonomic visual cadences. 100% local, private, free & open-source.
