Can someone please clarify which is the better sound, is it DTS or Dolby 5.1?
umm, not sure if this is the right forum, so heres a link
In short, DTS. As far as I know it has a wider frequency range for the rear surround channels. The same frequency range as the front stereo channels. This comes at a price though - a DTS soundtrack takes up more space on the DVD comparred to DD5.1
You're going to need a good DTS amp and good set of speakers to really apreciate the difference though.
Info appreciated and explains why region 1 dvds often in DTS but have less features.
Mod - Moved to more appropriate forum, fraggle.
I think that both Dolby and DTS have the same frequency range for all of the descrete channels. I belive there is some differnece between the way the sorround backs are used.....I only have 5.1 so havent really studied the white papers etc on this.....have to get on board with that!
However, as stated before, you need a really good system to really notice the difference between the two. Even if you can hear a difference, your never quite sure whether its a good one, bad one or just plain differnent!
There is loads of theory that is probably irrelevant.
In practice it is down to the mastering of the individual disc and on some, DTS has been mastered better and on some it is Dolby Digital that is better.
DTS does tend to be mastered louder than Dolby Digital which some interpret as sounding better and they have the better marketing department by far.
this has been discussed to death, just do a quick search.
I think there's no point discussing this subject when there's loads of threads about it. AND the above URL has a great non-tendentional article about the subject...
Why are you asking us?
Do you like the sound of one over the other? If so, that one is better.
I read on the DTS web-site, that DTS surrounds have a frequency range of 20KHz to 80Hz. I'll have to check it again.
But Dolby is full range i.e. 20KHz to 20Hz.
Here's the DTS 5.1 cinema frequencies.
On cinema DTS-ES though, the surrounds are full range. Click on the ES decoder, on the same page.
There's a little bit on home DTS here:-
I would of thought that the home versions, are mixed the same has the cinema.
Ok, I did this in the last EX/ES thread so will do it again here.
To set the record straight:
Home DTS is very different to Cinema DTS so essentially ignore info about Cinema DTS as it really doesnt apply here. Cinema DTS rear channels are limited to 80hz-20khz as the LFE channel is encoded into the rears (cinema DTS is a 5.0 not 5.1 system). This is not the case with Home DTS.
As for the home codecs, the frequency range of the channels varies depending on the bitrate of the codec. Full-rate DTS(1.5MBit/s) has a response up to 24khz and half-rate DTS (754kbps) goes up to 19khz. Dolby Digital response is quoted as extending up to 20khz at 448kbps and 18khz at 384kbps, but then again DD will combine channels at higher frequencies.
As for which is better, well I think it's fair to say that Full-Bitrate Home DTS is indeed a better format than full rate home Dolby Digital. A blind comparison on a good HT setup will reveal a less compressed and more involving sound, but then again seeing as almost all DTS dvds are half-bitrate, which does not sound noticeably better, although this is always subjective, it comes down to which comes from the better master.
Although if you are talking about 6.1 films, then DTS ES 6.1 Discrete is a far better option than Dolby Digital 5.1 EX, but there are still a sadly lacking amount of titles featuring DTS ES Discrete.
If DVDs are released with DTS 6.1 Discrete or DTS 96/24 soundtracks or ideally a combination of both (although I believe this combination isn't possible) then the choice would be easy, DTS every time.
P.S. Debating the comparitive frequency ranges is pretty pointless anyway as most humans hearing tails off at around 16khz, but I guess if you were playing movies for your dog you'd want him/her to experience it as faithfully as possible!
