A typical binaural recording unit has two high-fidelity microphones mounted in a dummy head, inset in ear-shaped moulds to fully capture all of the audio frequency adjustments that happen naturally as sound wraps around the human head and is "shaped" by the form of the outer and inner ear. This technique creates stunning three dimensional sound, and an almost palpable sonic presence. Wearing headphones the listener experiences the sound as if present in the exact place where that sound is being recorded.

contains violence uses this method for live sound transmission, transporting the audience into the rooms they are watching and then into the heads of the protagonists and then perhaps, while you are there, you can suck out their souls.
