Guides to binaural beats and the brainwave bands
What a binaural beat is, how one is made, what it needs to work, and how the brainwave bands are defined — with the research reported as it stands rather than as anyone would like it. Each guide is written to be read on its own, so start wherever your question is.

Hear the thing the guides describe. A generator that plays a beat in the browser and shows the frequency each ear is being given as you change it.
Or hear one instead of reading about it.
Fourteen journeys whose beat frequency moves over time, free to play, and a builder for authoring your own curve. Stereo headphones needed.
