Sub-Delta Sleep — 0.7 Hz Deep Rest

A slow, sub-delta soundscape built around a gentle 0.7 Hz rhythm for deep rest and sleep. Two binaural pairs form the foundation, 100 and 100.7 Hz over 50 and 50.7 Hz, each creating a 0.7 Hz beat, so the soundscape is best experienced with headphones. A soft tremolo at 0.7 Hz adds a slow breathing motion, while a quiet isochronic pulse keeps the same unhurried pace. Centered harmonic tones at 111, 222, 396 and 528 Hz drift slowly underneath, and a soft pink-noise layer moves like a distant wind.

As a Bisochronic session it pairs binaural and isochronic cues so it works on headphones or speakers. Let the volume stay low and comfortable, and simply rest as the sound rocks you toward stillness. This is sound for rest and relaxation, not a substitute for professional care.
