[QUOTE="Prowler573, post: 1094866, member: 561023"] Not any [I]better[/I] of an explanation than Jmac's...just a bit more detailed.. Taken from Crutchfield's 'Learning Center' pages: [B]Dolby Digital: A higher level of realism[/B] Dolby® Digital quickly established itself as a reigning surround format, largely thanks to DVDs. Although Dolby Digital, strictly speaking, is a particular method of encoding audio information digitally, the term is often used to refer to 5.1-channel audio — its most popular form. In discussing Dolby Digital surround sound, we'll be focusing on this multichannel format. Unlike Pro Logic, Dolby Digital 5.1-channel audio is a "discrete" multichannel surround sound system. Discrete means that the sound information contained in each of the six available channels is distinct and independent from the others. These six channels are described as a [B]"5.1-channel" system[/B], because there are five full-bandwidth channels with 3-20,000 Hz frequency range for front left and right, center, and surround, plus one "low frequency effects" (LFE) subwoofer channel devoted to frequencies from 3-120 Hz. Advantages to Dolby Digital include the following: [LIST] [*][SIZE=8px]Dolby Digital is the chosen multichannel digital audio format for DVDs and HDTV [/SIZE] [*][SIZE=8px]any receiver with Dolby Digital decoding can also decode Pro Logic [/SIZE] [*][SIZE=8px]six discrete channels; sounds can be placed much more precisely, for improved dialogue clarity, soundstage size, spaciousness, and realism [/SIZE] [*][SIZE=8px]you get [/SIZE][SIZE=8px][I]stereo[/I][/SIZE][SIZE=8px] surround channels; you can hear separate off-screen sounds to the left rear and right rear simultaneously [/SIZE] [*][SIZE=8px]you get a dedicated subwoofer channel, for plenty of deep bass [/SIZE] [*][SIZE=8px]thanks to digital encoding, you enjoy greater accuracy [/SIZE] [/LIST] [B]DTS: Another 5.1 surround option[/B] Like Dolby Digital, DTS® provides 5.1 channels of digital audio. However, DTS uses less compression than Dolby Digital. As a result, some say that the sound produced by DTS is slightly more accurate than the sound produced by Dolby Digital. The down side is that most DTS DVDs don't have as much room for extra features (like commentaries, foreign languages, and multiple versions of the movie). Also, there are very few DTS DVDs or CDs available, compared to the number of Dolby Digital DVDs. [/QUOTE]
