Dolby Digital 5.1 vs DTS 5.1

Its all surround to me. Please add in THX. As someone once said to me, "you'll never tell the difference, it's just different formats for recording surround". I don't know this to be true, but I bet I could never tell.
 
I believe DD is compressed and DTS is not. DTS sounds better IMO and it should be the standard for DVD but oh well.
 
DTS sounds better.. its uncompressed i think.. or a higher bitrate.. if i have a DTS opntion on teh dvd, i take that.. my receiver can decode DTS.
 
DTS has the ability to sound better as it has higherb nadwidth, but for the most part, many films treat it as a secondary item, defaulting to the nearly ubiquitous DD. This is why DD's might sometimes sound better if the DTS is rushed.

That said, if mixed right, DTS is AMAZING.
 
Performance wise DTS "should" be better.

But as always it depends on the mix/recording.

For example I can take a SACD and it will sound worse than the CD version just because the recording/mix sucks.

So like all things audio - "it depends"

Thats the same as Dolby digital just with a rear channel added.

DTS IS COMPRESSED. Its just at a higher bitrate. Most of the time DTS is the better choice as long as they didn't mess it up completely.

THX is not a surround format

Would like to know as well.

same as DD, except it has a matrixed rear channel (rear is derived from the surrounds)

DTS-ES is a true separate rear channel (rear is a totally seperate channel).

DTS-ES>DD-EX>take a pick between DD and DTS. But then again, it all depends on the mix/studio.

Could be wrong here but I don't think the rear channel is matrixed in DDEX. That would be if PLIIx was applied. However if you apply PLIIx or the equivalent to DDEX then it would matrix the rear channels. Again, could be wrong.

I'm pretty sure EX is a matrixed rear channel from the surrounds and NOT a descrete channel (something to do with the frame format not allowing it?) and the rear channel is derived from a phase shift.

That was always the big difference in 6.1/7.1 systems. ES is discrete, EX is not. IMHO both work very well.

But It's been a while since I've delved into the format so I could be off base.

Just looked it up. Turns out what I said was correct although you have a point too.

DDEX = discrete rear channel http://www.dolby.com/consumer/technology/dolby_ex.html

DD surround EX = Matrixed http://www.dolby.com/consumer/technology/dolby_surround.html

So true. I have 3 CDs that I always demo with and they sound better than all of the SACDs Ive bought. Never did notice a audible difference between DTS and 5.1, even on separates.
 
DTS takes up an enormous amount of disc space compared to DD. That's why discs that contain a DTS option usually have very, very little else on the disc. Thus if your goal is to pack as many features onto just one disc in order to save the costs of a producing a double set, you usually will avoid DTS altogether. This page does a lot to compare the two:

you missed the point...

"carry the encoded extra surround channel in their subsequent DVD releases"

It isn't a discrete channel.

"On the film itself, the additional back surround information contained in the Surround EX soundtrack is matrix-encoded onto the regular left and right surround channels of conventional Dolby Digital 5.1 soundtracks. "

Most receivers will allow you to chose what you want depending on the SB flag detect which is iffy at best.

SB on EX is matrixed.

True,

And IMHO, this is where superbit releases shine. I know, I know...some are marketing gimmicks - but many of the strive to pack the most video and audio quality to the film itself.

I'm a big fan of two disc releases. First disc = movie, second disc = everything else.

Thank you, I just read somemore and found out the rest of the story:

DDEX = Matrixed rear channel derived from surrounds

DTS-ES Matrixed = same as above

DTS-ES Discrete = true 6.1

So even DTS has a version that isn't discrete. However they are the only ones with true 6.1
