What's the difference between dolby and dts?

Question

DVD's have both... which should I choose?

Answer 1

DTS stands for digital theater systems and is a less compressed form of surround sound. I think it is most often better but this is a matter of personal choice. DD is the default standard for surround sound and it shows. make sure you DVD player has DTS decoding and for best results use the uncompressed analog audio outs to your amp/receiver. Try both when watching a movie some swear by one but it really is a matter of personal preference, and is greatly dependent on what equipment you have.

Answer 2

Dolby Digital and DTS are competing cinema sound formats. But without entering in technical details they are pretty much equivalent in terms of performance. Nevertheless, they have this important difference:

Dolby Digital is the standard for DVDs so it has to be present in all discs. DTS then is like an aditional option for DVDs and mainly the studios decide if they want to use it or not.

Maybe you're now thinking: how is that this could be important? I'll explain that...

If studios must include the mandatory Dolby Digital Soundtrack, why will they bother to include a DTS one?

The answer is that when including a DTS soundtrack they take advantage of it as a special DVD feature, but to make it real (not just marketing strategy) they usually make new better quality transfers.

So when DTS soundtrack is present will be the best choice.
If it was recorded making a better quality transfer than the Dolby Digital one you will be taking advantage of it. If not then you will have a DTS equivalent to the Dolby Digital soundtrack. Nothing lost either.

To include additional DTS soundtrack inferior to the Dolby Digital one would be more work for the studios and will be no added-value feature)

Answer 3

I don't know the technicalities or the true science behind this issue. However my Ears and Brain enjoy DTS far better. Of course you have to have a DTS decoder & Digital audio cable in order to use it i think.

Anyways, i actually did a test less than 24hrs ago watching Pearl Harbor. It was during the first part of the attack when one of the ships was bombed with a bomb that took about 5 seconds to detonate after it crashed through various decks of the ship before landing in the kitchen with the black sailor pealing potatoes. Hearing the wood splitting, then the metal on metal clangs, and then the final explosion was like night and day when played in DTS vs. Dolby. Test for yourself. Watch a crazy scene with tons of action then change the audio, hit rewind and watch again.

Answer 4

Dolby removes the sounds that are too high and too low for humans to hear...It saves space on a DVD, programming wise...That means only 20-20,000Hz for Dolby.

Now DTS takes up more space on a DVD because they leave in sounds all the way up to 100,000Hz...No, we can't hear that high, but those sounds DO affect the sounds we CAN hear.

Most people can't hear a difference on their Home Theaters...I suggest trying them both...You'll find that Dolby and DTS are the "Coke and Pepsi" of surround sound...Click this link for some more info: http://www.avtruths.com/dolbydts.html

Answer 5

Hi I might be wrong but i think Dolby is a noise reduction system that removes unwanted high frequency sounds from the recording to achieve a quieter background (or that's what it used to do to improve the sound of the music cassettes)
DTS or Digital Theater Systems is a dynamic range expander to approximate the intensity of live musical instruments and sounds in a playback medium (still only guessing !)

Answer 6

DTS is less compressed than dolby digital and carrys more data. it has a more detailed sound in my opinion.

Answer 7

dobly is the best format for watching movies its more clearer than dts.
