What's the difference between AC3 5.1 and DTS 5.1?

[Morea]

Hello everyone,

I am a newbie here and I had a simple question and I was using dvdshrink and the backup in question contains two english soundtracks named as AC3 5.1 and DTS 5.1. I need to know something about these two and which one should I keep and the actually what is the difference between both.

Thanks

The difference is a number of megabytes. Plus with DTS you required a decoder on your sound management system (if you can have one) to hear it. There are most of the users can not tell the difference between the two. I uncheck entire audio except AC3 5.1. It will save a lot of space for the movie (less compression if any).

Within the most confusing media components of home theater, the subject of audio decoding ways stands the biggest. The market hype of the home theater industry will try to sell you on number of different "standards" components, but only some of them are actually necessary when it comes to the quality of your home theater.There are commonly three formats on the market currently that are of significance. Dolby Pro-Logic, Dolby Digital and DTS. You will search these logos on the front of different receivers and DVD players alike. Dolby Digital 5.1 is a latest format which has become more famous with the coming of DVD.

This audio format provides any number of suggested channels up to five primary channels and one low frequency effect channel. Dolby Digital is the much popular recent decoding mechanism for DVDs and provides following improvements on movie soundtracks:

• Improved clarity of center channel dialog
  
• Greater separation of music from dialog
  
• Discreet surround channel use. Missiles flying from rear right to rear left.
  
• Greater overall frequency range for all six channels.
  
• Greater accuracy in all six channels.
  
• More accurately represents the films original score.

DTS is a competitor of Dolby Digital. It also provides 5 channel with lower frequency effect channel, but it is not supported with the Dolby Digital soundtrack. The marketing babble that goes out of DTS tells that it uses a lower form of compression that provides you a good overall sound for your movies. I personally have not found it to be the case. Getting to both DTS and Dolby Digital versions of the film gave me little sense that one was good than the other. Dolby Digital or DTS can both sound very well or shoddy based on the quality of the soundtrack.

I certainly suggest you to getting DTS supported equipment for both your DVD player and your receiver since the price is minimal. There are so many DVDs now produced with both Dolby Digital 5.1 soundtracks and DTS 5.1 soundtracks, letting you pick the version to listen to. One attractive side note, Dolby Digital contains a signal compression properties for late night viewing that DTS does not. This facilitates you to get dialog and quiet scenes at their normal volume while louder scenes are suppressed.

Dolby DIGITAL (DD) and dts are two different methods through that you can encode audio. AC3 is an very previously used concept for DD and harkens from the times of Laser Disc Players. DD is from Dolby Laboratories, Inc. and dts is by Digital Theater Systems, Inc. Both contains the capability of encoding five full channels and one Low Frequency Effects (LFE) channel. The Five channels are Front Left and Right (FL, FR), Front Center (C or FC), and Rear Left and Right (RL, RR). The EX versions combines a 6th Rear Center (RC) channel. So, when you get interact with 5.1, that indicates. 5 Full channels and 1 LFE channel. 6.1 suggested 6 Full and 1 LFE etc.

Traditional two-channel system has been gradually fading out, and the current 5.1-channel audio processing system is relatively perfect audio and video solution. Nowadays, 5.1-channel has been widely used in various types of traditional cinema and home theater. We often hear of "Dolby Digital 5.1-channel", but a lot of people do not know the specific meaning of it. In fact, 5.1-channel is the use of five speakers and a subwoofer to achieve a kind of immersive music player mode, which is developed by Dolby, so called "Dolby Digital 5.1-channel." 5.1-channel system uses two channels for speakers at the front—left (L) and right (R), one channel for speaker at the center—center (C), two channels for surround speakers at the rear—surround left (LS) and surround right (RS), and one low-frequency effects channel (LFE), for 6 speakers are all around, it will gives rise to sense of reality in theater.

What you need, depends on home theater system. DTS is usually for the more enthused home theater connoisseur.I almost always encode my DVD's to Dolby Digital primary and DTS second, mainly because Dolby Digital is easier to use and more supported.
