Therapeutically processed ambient music designed for deep stillness. Layers: brown noise bed for cognitive grounding, 55Hz sub-bass for vagal nerve stimulation, 110Hz binaural beats for alpha brainwave entrainment, 9kHz low-pass warmth filter. Sidechain-compressed so therapeutic layers remain subliminal beneath the music. Research: brown noise (Inspire the Mind, 2024), binaural beats (Ingendoh et al., 2023), vagal stimulation (Neuvana).
