[kwod-ruh-fon-ik] /ˌkwɒd rəˈfɒn ɪk/
of, noting, or pertaining to the recording and reproduction of sound over four separate transmission or direct reproduction channels instead of the customary two of the stereo system:
a quadraphonic recording.
1969, irregular formation from quadri- “four” + phonic, from Greek phone “sound, voice” (see fame (n.)). The goal was to reproduce front-to-back sound distribution in addition to side-to-side stereo. The later term for the same idea, surround sound, is preferable to this.
