Poll: Should Sony use DTS-HD Master Audio or Dolby TrueHD?

I think the disagreement is about all the "features" attached to Dolby - such as Dialnorm, DRC, the -4DB stuff, that is a headache to steer through.

Those features are for the average consumer as well as the audiophile.

I also think the lossy core track of DTS is more attractive to those who can't decode either format.

Because...? All I know is there are far more devices that are DD ready (this includes HDTVs and PCs, not just receivers)

So, do nothing and you get perfect lossless from DTS-HD; twiddle volume knobs, disable/enable stuff on players or receivers, and get perfect lossless from TruHD.

So you never have to adjust your volume for DTS tracks? One size fits all?
DRC to "off" is a one button push.

Maybe it's the difference from driving a car with an automatic, or a stick. Most folks prefer an automatic for daily driving.

TrueHD is a vehicle automatic with antilock brakes, airbags, and other safety features.

Does it really matter if Sony should use TrueHD or DTS-HD MA? I think both are great, and despite missing the Linear PCM tracks, both are fairly good audio codings.

Well in TrueHD and DTS-HDMA's favor, they tend to be 24bit master audio tracks. Typically, LPCM had just 16bit audio, even though the actual master was 24bit. So have the compressed lossless audio that matches the 24bit master audio is preferred, though I never turned my nose up at the LPCM tracks that were 16bit.

Good point. Though there are many LPCM 16 bit tracks that are superlative, the codecs certainly hold a technical advantage when you look at how they've actually been implemented.

You are correct. In those moments the TRUEHD combined with the DD 640 would be more efficient than the DTSMA as the comparative would be 640kbs to 1.5mbs. However those moments would be so fleeting as with most films there are no moments of complete silence save credits with no music over them.

In the real world of a film, I question that there would be very few times the TRUEHD would dip below the 640 threshold, perhaps few when it would dip under 1.5 for lossless.

I don't believe I have stated a preference for either codec on this website or any other.

And I am correct on those auditioning 640kbps tracks. I don't think you attended the listening session

You don't have a preference on the lossy version of the codecs?

And I have been present at codec shootouts, there have been more than a few over the years.

Its high time they should use DTS-HD MA after all blu ray is incomplete without it.. i would love to watch AIR FORCE ONE, TAKING OF PELHAM 123 to name a FEW..
even WARNER should follow DTS

[RiseDarthVader]

The problem is people still think DTS sounds better because of the DVD days where DTS did sound better and less compressed then Dolby Digital which is FACT but DTS-HD MA and Dolby TrueHD sound exactly the same when levels are matched and using the same mix FACT.

See the poll? Doesn't matter. The debate is over. If Sony wanted to know which codec the masses on here want; now they know.

this is not good behavior ,even if Lossless and lossless does match when you balance it ,i will and still favor DTSHD master audio over its rival.i'm not deaf nor i'm not in position to differentiate what is good and bad.

So respect my opinion as i did respect other opinions in this thread and obey to this poll result,Its clear what customers want.Sony you can give the last word.

Really, only one setting for me to get lossless from TrueHD and the same for dts-ma.

dts-ma required me setting my HDMI output to PCM.
TrueHD I simply turned DRC to off.

I really wish some people would just speak for themselves, and not generalize that everyone else doesn't know what they are talking about. Don't ASSUME!

[CAB]

I don't assume, rather, I know Doby knows what he's talking about.

Science doesn't assume. You can prove it for yourself:
1) Take a CD and use EAC to get a 100% copy of a single track.
2) Note the checksum.
3) Convert it to .shn and back to .wav using MKV
4) Convert it to .flac and back to .wav using FLAC Frontend
5) Convert it to .ape and back to .wav using Monkey's Audio
6) Look at the checksum, does it match the original checksum of the file?

#6 is rhetorical if you did everything correctly - the answer is YES. The same exact audio file is there. Do you know why? Because FLAC, SHN and APE are all lossless encoding schemes just like TrueHD and dts-ma. Due to the fact that MOST people are suggesting Sony should adopt dts-ma due to sonic/aural reasons then there is nothing to assume - those people don't know what they're talking about.

For the minority that have other reasons - built in dialogue normalization, better legacy support, efficiency, etc., those are all valid reasons to have an opinion, but those reasons are completely in the minority, hence MOST people don't know what they're talking about.

I really question how it will impact video. There is plenty of (wasted) disc space not used on every movie.

However, I don't really care what they use.
