Whispering Angel is a soothing, hypnotic sleep channel with binaural beats. Recommended to listen to right before sleep to slow down the brain and sink into deep relaxation. Adding a binaural beat to a music track can help our brainwave frequencies align to the added binaural beat, which then can help sleep, slow down your heart rate, for example. When listening to binaural beat audio, it is recommended to use headphones for maximum benefit. Whispering Angel is 5 hours in length for Calm Radio members and 8 minutes for free listeners.
