5.1 multi-channel audio refers to stereo audio program intended to be monitored through six channels: five full frequency range (20Hz to 20KHz) channels intended as Front Left, Front Center, Front Right, Left Surround, and Right Surround, and one frequency limited (below 120Hz) channel for the LFE (Low Frequency Effects), or Subwoofer track. This format is also typically referred to simply as “5.1.”

7.1 refers to multi-channel audio intended to be monitored through eight channels: seven full frequency range (20Hz to 20KHz) channels and one frequency limited (below 120Hz) channel for the LFE (Low Frequency Effects), or Subwoofer track.

7.1 multi-channel audio has several theoretical channel configurations, but only two are routinely encountered in practical applications:

1) The Sony SDDS format, used primarily in theaters, arranges the seven full frequency range channels as five channels across the front – Front Left, Front Left Center, Front Center, Front Right Center, and Front Right – along with Left and Right Surround channels.

2) Blu-ray Disc® can accommodate several 7.1 channel configurations. The most common configures the seven full frequency range channels as Front Left, Front Center, Front Right, Left Surround, Right Surround, Left Back, and Right Back.

Can we enjoy 5.1 and 7.1 multi-channel audio while watching DVD movies on computer? Yes, this could be managed by using a DVD player program like DVD X Player which has a built in 5.1 channel Dolby Digital decoder for playing back the DVD movies on computer. You can enjoy the theater-like surrounding sound effect as well as home theater surrounding sound effect with this amazing DVD player software.
