Unlike a stereo recording, a binaural recording makes it possible to hear surround sound with just a standard pair of headphones .Binaural recordings are made using a special microphone. Originally, these mics were a life-size mannequin head with condenser mics where the ears would be. The natural structures of the outer ear on the mic, direct the sound so that the listener can not only perceive sounds that are located to the left and right, but also sounds that are located to the front and back.
