7.1 Channel Sound common name for an eight-channel  audio system commonly used in configurations. It adds two additional speakers to the more conventional six-channel audio configuration. As with 5.1 sround ursound, 7.1  sound positional audio uses the standard front,  and (subwoofer) speaker configuration. However, whereas a 7.1 sound system combines both surround and rear channel effects into two channels (commonly configured in home theatre set-ups as two rear surround speakers), a 7.1 surround system splits the surround and rear channel information into four distinct channels, in which sound effects are directed to left and right surround channels, plus two rear surround channels.
