I know someone already picked on this post but I just had to clarify something.....

Dolby Pro Logic isn\'t 3 channels, it\'s a two channel signal that is matrixed into FOUR channels.  Evidently you\'ve forgotten about the center channel my friend.

I should say though that everything else this guy\'s said makes perfect sense and you all need to stop picking on what he\'s saying.

He was just very confusing and from his posts it looked like DTS is actually inferior to DD. LFE channel *weak* on DTS?!

Well, you can\'t argue personal taste or preference.  When I set these systems up, they look the same on the RTA and thus would theretically sound identical in the same room.  Let\'s put it this way folks....

We\'re talking movies here, but the theory should apply to all forms of media.  When a soundtrack is recorded, it\'s recorded by whomever\'s making the film (or someone they\'ve hired anyway).  Then it\'s mixed and mastered by an engineer, who again, works for the folks making the film.  These engineers don\'t work for Dolby or DTS or anything, Dolby and DTS are just tools they use to transfer the sound data from the recording to the auditorium.

Now, as a sound engineer, it\'s my job to make these sound systems reproduce that sound track according to standards that these engineers expect me to comply with.  This way, the movie\'s sound track is faithfully reproduced.  I don\'t however, have any control over what the actual recording will sound like in relation to it\'s digital counterpart.  That\'s taken care of at the studio where the film was mixed and mastered.  So in short, if the Dolby and DTS mixes are the same at the studio, they should therfore be the same in the auditorium.

If you\'re hearing a difference, it\'s not DTS or Dolby\'s fault, it\'s the engineer who mastered the soundtrack\'s fault.  So in conclusion, you won\'t be able to argue to me whether or not one is superior.  And that whole thing about DTS using more data is just stupid.  Regardless of the bit rate, you either have a digital signal or you don\'t.  More digital data coming through the DSP doesn\'t equal better sound coming out the other end, with a digital signal, it simply works or it doesn\'t.  There is no degredation of a digital signal.... and I got news for you folks, it all ends up a big fat analog signal anyway.

Now, I didn\'t get the impression that anything he said was confusing.  I think that if you carefully read what he said, you\'ll find he\'s being very clear about things.  It\'s when a  bunch of other people jump in there and make short comments about it, throwing in little pieces themselves, often these little pieces being disinformation, that things begin to get confusing.

I can\'t believe what you\'re saying. Your above sentence could be as well translated into this: 256kbit/s MP3 sound as good as 64kbit/s MP3 just because both are digital, and signal simply works or doesn\'t!

Or how about this: DivX at 1000kbit/sec according to you, looks the same as DivX at 500kbit/sec.

Bitrate is extremely important thing in digital media, and I can\'t believe that a sound engineer can say something like that...

DTS uses 2:1 or 4:1 compression while DD uses 14:1. They are both using lossy compression, just like MP3 is (for example), and technically, there is a difference in quality.

Okay bud, here you go:

Take a recording and compress it 4:1, then compress that same recoding again in 2:1.  When you\'re done doing that decompress them both and what do you have?

Answer: Two identical sounding recordings.

Dolbytone, don´t get me wrong... I´m a fan of your great posts, but I´m not sure if this is the right way to explain that kind of compression...

DD or dts doesn´t work like rar or zip. If you use that kind of compression (like mp3) than everything above or below a given rate is LOST ! If you decompress it, those lost information won´t come back... I just don´t know if I´m 100% right here...
So I think, if you compress it 4:1 more info´s lost than under 2:1 ?!

Okay, I oversimplified there Eye.  The fact is, that this whole competing digital formats thing has or is nearly escalating to a level that approaches the DC Vs. PS2 fanboy discussions and it\'s getting on my nerves.  Direct comparisons of these two formats isn\'t easy, but from what I\'ve seen when setting these systems up, there is a remarkable identicalness to them considering the huge difference in data transfer.  As a result, I must conclude that bits simply isn\'t all that matters... Much like comparing the PS2 and XBox stats side by side.  Read this please:

"So is Dolby Digital better than DTS? No. I merely preferred Dolby Digital over DTS under these particular conditions. (Did the cold New York City weather in February play havoc with my delicate Miami temperament?) My tentative conclusion is that the differences are relatively small. In some ways, that\'s disappointing because DTS has been touted as sounding superior. On the other hand, the outcome of this test has increased my respect for Dolby Digital. It works really well for both multichannel movie soundtracks and music.

Anyone with the DD logo on his system should not feel limited by it. Crank up your system and enjoy it! And if you\'ve made the extra investment in DTS, it\'s pretty darn good, too - just be careful how loudly you brag to your Dolby Digital-only friends."

Dolbytone thanks for clearing up everything, i was expecting someone like you to post in this thread :cool:. Also about the pro logic thing i meant 4 channels because there is front right, front left, center and matrixed (mono) rear channel compare to all discrete channels that DD and DTS has to offer. I admit i made a mistake for saying three and not four but i realized it after clicking the submit button and i couldn\'t edit it afterwards :(
