Our Binaural Beats - Brainwave Music contains four programs for relaxation. I use the first of these musical programs all the time to make recordings. Binaural Beats sends audio signals that help train the brain to move into certain levels of consciousness. The music is wonderful. The first mp3, the Mind Rise Audio, is my favorite. It's 40 minutes long, and you can use it as background for hypnosis or anything you like. You get all 4 of the audios with this package! They're sent to you as mp3s, and you can download them onto your computer or any device. $24
