8 Hours of relaxing ambience for sleeping or meditation with an 8 minute theta wave binaural descent from 8hz to 4hz leading into 8 full hours of gentle red noise waves with a 4hz deep theta wave binaural program. Jellyfish Intro fades to full black screen after ~100 seconds. NOTE: I am getting some feedback that this audio may trigger hypnagogic states rather quickly so be aware. I would not suggest this audio be used with any substances. Analog Red Noise - Moog One Synthesizer. Binaural Sin waves - Precise Digital generation.
