With respect to recording, 5.1 means that the recorded soundtracks are mixed to five main channels: left, center, right, left surround, and right surround, plus a low-frequency effects (LFE) bass channel (called a ".1" channel because it covers only a fraction of the frequency range of the main channels).

With respect to home playback, the term 5.1 mean that there are five main speakers, plus a subwoofer, in the playback system. (The subwoofer reproduces the LFE channel recorded on 5.1 soundtracks, plus any bass the main speakers cannot handle.)

Stereo is able to produce two dimension sound (left & right). This produces a flat or two dimensional effect.

5.1 surround sound produces three dimensional sound; left to right and front to rear. When properly mixed, the result can be stunning. Instruments and vocals can be placed not just left and right but front to back resulting in a sound that is like a live performance.


The three extra channels (Center and Left and Right Surround) allows the audio engineer to deliver over 2 1/2 times as much audible information to the listener. Instead of cramming all of the audio tracks into two full range channels, the sound can be separated into 5 distinct full range channels. This allows the listener to hear all the subtleties of the music. When the volume is turned up the music does not simply get louder, you can actually hear more.

The DVD format also allows for the inclusion of high quality video. Video of the recording session can be added to enhance the listening experience. Artist interviews are also possible allowing listeners to gain insight and better appreciate your music.

All DVD players can play 5.1 audio. All but the least expensive have outputs for surround sound. Take a trip to your local electronic store and you will find that stereo systems have been replaced with surround sound systems and CD players have been replaced with DVD players. DVD players now out sell VCRs and are quickly becoming the standard for audio and video in the home.
