daTextBox=<font size="12" face="arial" color="#000000"><br>Dolby Digital is a high-quality multichannel audio coding system, and is the standard for multichannel digital audio in DVD, HDTV, Cinema, and now games! Dolby Digital can encode up to 5.1 channels of audio into a single, compact bitstream. This bitstream can be decoded by a Dolby Digital decoder.
Dolby Digital 5.1-channel audio is composed of five full-bandwidth channels (Left, Right, Center, Left Surround, Right Surround) and one bass-only channel, called the LFE. The LFE channel is used for extra bass in Dolby Digital soundtracks, and is band limited to frequencies less than 120 Hz.
