This refers to a surround sound format consisting of 5 full range channels and one LFE channel (see the next entry). It consists of Left, Center, Right, Left Surround, Right Surround.7.1. This is reminiscent of, but not exactly the same as the old 70mm soundtracks. The current 7.1 has L, C, R, LS, RS, and LFE like 5.1, but adds 2 more speakers behind the screen between the center and left,and between the center and right.

The channel does not necessarily have to be band limited, as in the option to use it as a height channel in DVD-A, but when used as an LFE, it is of course for low frequency information. It is a discrete channel, not a crossover network to derive the low frequency information from the main program. However, in most end user systems, bass management is in use, which actually does divert the sub bass from the other 5 channels to the subwoofer along with the discrete LFE channel information.THX: Tomlinson Holman experiment. Tomlinson Holman and Lucas film developed these guidelines for standardization of cinema sound systems and theater acoustics. There was later developed a standard for home playback systems and also a professional small room standard as well. The idea is that if your mix room and the playback theater are THX certified, the sound will be experienced by moviegoers as intended by the mixers and directo...
