What does DTS, Dolby 2.0, Dolby 5.1, AC3 mean?

DTS is the abbreviation for "Digital Theatre system", which means "digitized cinema systems". Technically, DTS is completely different from other sound processing systems, including Dolby Digital. Dolby Digital Stores the sound data in the perforation of the film, because the space constraints must be in a large number of compression patterns, which have to sacrifice part of the sound quality. DTS has solved this problem in a simple way, by storing the sound data in another CD-ROM to synchronize it with the image data.
This will not only increase the space, but also the data flow can be relatively large, you can store the audio data CD replacement, to play different language versions.
AC3 is the Dolby Digital 2.0 (Dolby 2.0) is also 5 channels, but only two channels have sound. In Dolby Digital 5.1-channel system, using left (L), Medium (C), right (R), left (LS), right (RS) 5 direction of the independent channel output sound, in addition to a subwoofer channel, because its frequency range of only the standard channel 1/10, so called 0.1 channels, 5.1 channels so this name.
Listening to this kind of music will create a sense of being in a concert hall, feeling the direction and change of the sound, the scene is full of feeling. When playing DTS encoded WAV, you need to change the WAV suffix to DTS, and if you are loading the cue file, Then change the cdimage.wav in the cue file to Cdimage.dts, and then you can use Foobar to release it. DTS-CD just porting DTS technology to CDs, and DTS-CD generally has two sources, one is that record companies use multi-track recording technology, and the DVD's DTS track is captured Come on. The current DTS-CD is not a successful audio format, because more than the average CD more than four tracks, and the capacity of the same, it can be inferred that the quality of each track is not as good as the ordinary CD, but the pursuit of a wrapping effect. Play DTS-CD to use 5.1-channel configuration, that is, the usual AV home theater, the speaker is 2 main speakers (front) + 1 central + 2 surround + 1 subwoofer. There are some cheap home theater in the mall without a subwoofer, or you can. On the computer to play this format requires WinDVD or PowerDVD, as well as virtual CD-ROM software, or on the engraved disc play, but the effect on the computer is generally not good, and few people on the computer configured 6 channels or even 8-channel speakers.

The sort is; Dolby 2.0 5.1 DTS (AC3)
