Definitions

1. A sound reproduction system that uses four separate audio channels and speakers positioned around the listener to create a surround sound effect

3. A type of audio system designed to deliver sound through four distinct channels, providing an immersive surround sound experience for the audience

Etymology: Quadraphonic is a compound of two parts: "quadra-", from Latin "quadra" meaning "four" (the same root behind "quadrant" and "quadruple"), and "-phonic", from Greek "phōnē" meaning "sound" (as in "telephone" and "symphony"). Put together, the word simply describes four sounds, or four channels of sound. The word's logic is built directly into its parts. Where ordinary stereo splits a recording into two channels, the quadraphonic approach routes audio through four speakers placed around the listener, so that sound can seem to come from behind or to the side as well as in front. The name therefore carries the idea of a four-part system in its very construction, rather than being a figurative coinage.
