DTS or 5.1 What's the difference and which is the best quality?
No idea what the difference is, but when watching movies I prefer DTS as it always seems to have more 'kick' to it.
dts is encoded into 5.1 surround or 6.1 surround similarly as dolby digital is. They are just different encoders, most view dts as superior with better sound. Have a read here to learn more http://www.dolby.com/consumer/technology/dolby_digital.html
oh god not this debate again...........
a recent poll on a certain other set of forums DTS got 2/3 of the vote.
its personal preference, i tend to find DTS has a better balance (no turning the amp up and down throughout the movie). also seems to give a more musical sound.
let your ears be the judge......
I assume you are asking the difference between DTS and Dolby Digital.
5.1 refers to a typical home cinema setup i.e. 2 front stereo speakers; a centre speaker & 2 rear speakers. The .1 refers to the LFC (low frequency channel) i.e. the subwoofer. you get 5.1 DTS & 5.1 DD.
I believe that DTS uses lower compression rates which gives a more detailed sound. I always find that DTS sounds 'louder' than DTS. As to which is 'better' comes down to personal choice.
Thanks, that's clear now.
How does AC-3 come into the picture?
That's the old name for Dolby Digital
Or more specifically, AC-3 is the name of the audio compression technology used in Dolby Digital.
I wonder how many of the supposed audible differences between the systems comes down to differences in approach though? They may not even play back at the same respective levels in a setup.
Dolby Digital uses dialog normalization, which adjusts the playback volume so that any two movies should play back dialog at the same level. It also usually phase shifts the surround channels 90°, so that DVD players can directly create a Dolby Surround-compatible 2-channel stereo downmix. Furthermore, the bass management used in production is supposed to differ a bit between the two systems, so it may match or mismatch flaws in a playback system, making them sound different.
Dolby Digital EX also uses a 45° phase shift to the left and right surround channels in opposite directions before encoding the back surround channel. I don't know if DTS-ES Matrix does that and what matrix decoder they use, if it's the decoder they designed for DTS Stereo, a deriviate of Neo:6, or a licensed decoder from someone else. DTS are a lot more hush-hush about their technology than Dolby.
So, they may behave differently from one another during production and playback for reasons other than performance.
And on top of that, the Dolby Digital and DTS soundtracks may not necessarily carry the exact same mix, but differently tweaked versions of it or maybe even two different mixes of the soundtrack.
I have a Toshiba SD-330E and Pioneer VSA-EO3 amp. They are optically connected. When I select DTS, I get no sound at all. What could the problem be? There is a bitstream/PCM option, is it something to do with that?
DTS is generally accepted to be better quality than Dolby Digital. However a lot of films do two different sound mixes for DTS and Dolby, with the DTS being a bit more 'gratuitous' and designed for people with good sound systems.
Also DTS-ES can be encoded as discrete 6.1 rather than DD-EX which can only be 5.1 matrixed to 6.1
For movies, both Dolby and DTS are OK afai'm concerned.
For music (or movies with an important music score) I prefer DTS as it is a bit more transparent and tends to leave the fronts intact.
Does the VSA E03 say it will decode DTS? If it doesnt your gonna get silence.
Dunno. My Brother in Law reckons it does but I'm not so sure.
You should see a DTS logo on the front of the amp (normally alongside the dolby digital logo) if it does. If not, then I'm afraid you can't use the DTS soundtracks.
This (I have no idea what language it's in...) dosen't show a dts logo on the front, so probably dosen't decode dts.
Looks like it's from the era of my old VSA E06, which was THX Ultra certified but didn't decode dts.
IMO, you're not missing much anyway...and well set up amp will sound good in DD or dts, regardless of whether it's an high end system or not...contrary to some posts here...
My point was more that if you are trying to listen at quieter volumes and don't want a large dynamic range you are sometimes better sticking to the DD track.
The amp has a "midnight" function for listening at low levels.
My whole system is compromised at the mo anyway, as I'm living in a small bungalow that I'm goiing to re-build soon so I won't loose any sleep until I can "design my own" room
