Live Binaural Player
Synthesised in real time — never a recording, never the same twice.
Wear headphones — binaural beats only work with stereo audio
delivered to each ear separately. Speakers produce a regular beat instead.
This session is being generated right now — it has never existed before and never will again. Each moment is a unique combination of frequencies and noise, synthesised live in your browser.
