I've been using binaural audio, "theta" inducing frequencies and other "audio drugs" for meditation for the better part of a decade. There are many places to find this stuff for free online (legally) and once you understand how it is supposed to work, you can throw stuff together in Audacity or Garage Band if you feel compelled to do so.

Some people are particularly sensitive to audio and visual stimulation that can create relaxation, disortientation, and other sensations. This is not news.
