Sub-Delta Deep Rest: 1.45 Hz

The Encephalon Bridge is a slow, settling soundscape built around a 1.45 Hz sub-delta rhythm, made to help you wind down and ease toward deep rest. Gentle binaural beats sit at 88.275 Hz and 89.725 Hz, with a soft 48 Hz sub-bass pulse and a 180 Hz isochronic tone all sharing the same 1.45 Hz pace, so the whole field seems to breathe together.

A warm harmonic lattice (222, 396, 528, and 963 Hz, lifting to 1444 and 2888 Hz) and a slow pink-noise drift add depth and a sense of grounding. This bisochronic session is best with headphones, lying down, and breathing slowly, before sleep or quiet meditation. This is sound for rest, not a substitute for professional care.
