Dolby Digital Vs DTS

[bloodstainedwings]

I have been reading up on these audio formats and from what I have read DTS is better then DD is this tru. When I watch a blu ray on my system Dolby Digtial is 640kps and DTS is 1.5MB. How can my reciver decode DTS HD when its not an HD sound system is the bitrate for DTS-HD higher then 1.5mb/s So if i sould confuised about all these audio formats this is my frist sound system to decode the formats.

DD vs. DTS is like the old MP3 vs. CD debate, except that *both* are a form of compressed audio, where as the HD audio formats are more akin to CD (lossless/uncompressed). DTS uses a higher bitrate, while DD claims to simply use more efficient compression. There has been a lot of evidence to support both sides of the argument. Personally, I haven't ever noticed a substantial difference, and I consider my system to be reasonably good, but I do sense some differences. The main difference, however, is volume. DTS tends to be louder given the same settings, but it also tends to have more LFE/bass. That said, for virtually every DVD that I've seen, that has a DTS track, the DD track also sounds better. Example. The theatrical release of Lord of the Rings vs. the extended edition. The difference between the two releases is staggering, but the difference between DD and DTS on the extended edition is marginal (from what I recall anyway).

If your receiver does not have the ability to decode the HD audio formats, then you need a player that can. The player then has to decode the soundtrack and down convert it to DD or DTS. Otherwise, the only way to get HD audio with a non-HD receiver is if your receiver has multi-channel analog inputs (usually higher end receivers), and your player has multi-channel analog outputs AND can decode HD audio.

Thanks for the replay. My system is just a cheap Panasonic 800W HTIB. Do you know the birtates of the HD Audio? my reciver does DTS at 1.5mb is that normal DTS? MY PS3 is my player. I am going to play around with it in the comming weeks. It blows what I had before out of the water. For $250 you can't bitch much that's for sure.

this a debate thats been going on for years.all the debates iv'e seen or read,maybe on paper dts is better,but if you were blindfolded,and had somebody switch audio from dts to dd,i doubt you would hear any difference
between the two.now people here and other forums will try to tell you different.when you listen to dd truehd&dtsma,same thing happens.
the same kind of debate happens with 1080p&1080i.this debate will go on for many more years.they mix movies the same in dd,dts pcm.has any one noticed that at the end of a movie,it doesn't say ddtrue hd or dtsma.all thats differnt is because of hdmi they have more bandwidth to play with hence uncompressed audio.if you want the best surround sound yet move up to a receiver or bd player with analog jacks and one that has dd truehd &dtsma.
just don't try to tell someone one is better then the other,because their not.
i have heard very loud dd and dts tracks,but when you read these debates,you'll notice they never bring up loudness because loudness doesn't make one better then the other.you may like one over the other but to say what you like is better then the other is just plain ''crap''

BSW, I tend to favor DTS-HDMA for cases such as yours. While both Dolby TrueHD and DTS-HDMA sound awesome on blu-ray, I prefer to see the DTS track because of the higher bit rate. For users that don't either don't have a receiver with HDMI or a player or receiver that can't decode TrueHD, the DTS audio delivered is still 1.5mbps, which beats out Dolby's 640kbps. Lastly, DTS tracks deliver 7 channel audio, while I have yet to see a TrueHD track with that offering. But soundwise, I think both deliver excellent quality. I do agree that DTS tracks have a more powerful LFE.

The Nightmare Before Christmas Blu-ray is a 7.1 TrueHD track. (only one i know of)

Overall though i also prefer the DTS-HDMA tracks to TrueHD ones. Sure there are some reference TrueHD tracks out there (Kung Fu Panda, Batman Begins, Dark Knight, Nightmare Before XMas) but i tend to have them playing at a slightly higher volume setting then my DTS-HDMA tracks. Still i guess i shouldn't complain on volume levels which are easily adjustable. Overall from the movies i have watched the DTS-HDMA tracks just seem to express a little more realistic depth in the sound department. I feel more immersed in the action then most of the TrueHD tracks i have. Plus the LFE does seem a slight bit tighter and stronger for the action too.
