Liminal Guides
Plain-language guides on how brainwave entrainment and frequency-based listening work, what the research actually shows, and how to put it to use in a session.
A practical walkthrough: which frequencies to use, how long to listen, and how to build a focus session that actually holds up during deep work.
What each brainwave band actually means, the mental states associated with it, and how Liminal's presets map onto the spectrum.
A clear-eyed look at the 432 Hz debate — the history of concert pitch, the actual evidence, and when tuning might matter for your listening.
How Delta and Theta frequencies fit into a wind-down routine, plus a simple session structure for falling asleep faster.
Where the Solfeggio scale comes from, what's myth versus measurable, and how to use the 174–963 Hz set without overclaiming.
The technical difference between the two, why one needs headphones and the other doesn't, and which to reach for in different settings.
Liminal turns every concept on this page into a one-tap session — tones, soundscape, and pacing included.
