Today with the popularity of Home Cinema systems, surround sound based on either Dolby or DTS encoding standards has started to become very popular. Although on the face of it things appear to be less confusing this time around, nothing could be further from the truth. Surround sound can be true equal four channel sound sources with the addition of a centre 'dialogue' speaker and a sub woofer but more commonly it is a stereo image with additional effects and ambience appearing from the rear speakers.
Not only is the way the channels are interpretted inconsistent but there are many different multi speaker systems using 3.0, 4.0, 4.1, 5.1, 6.1, 7.1, 8.0 or 10.2! The figure to the right of the decimal point indicates the LFE (Low Frequency Effects) channels. These occupy a fraction of the bandwidth taken by a normal channel (0.005 of a channel to be precise, but .1 represents it more simply).
