A type of sound recording and reproduction. Two microphones, each representing one ear and spaced about 6 in. apart, are used to pick up the sound energy to be recorded on separate tape channels. Playback is accomplished through a two channel amplifier (or separate amplifiers) or through special headphones wired for binaural listening.
