What are your thoughts on this subject

Well if your referring to Disney going way of DTS-HD MA audio in place of uncompressed PCM? Iam ok with that. I leaning toward that format over Dolby TrueHD. But thats not to take anything away form the straight PCM tracks disney has been useing.

Nothing wrong with the TrueHD tracks on Enchanted or The Nightmare Before Christmas, either.

Or National Treasure 2...

To the OP, just checking your previous posts as I've seen you start a couple of threads about Disney using DTS-HD MA now, I am curious why you keep bringing it up?

saprano · 11-10-2008, 10:04 PM

Cause he's curious just like you.

Anyway i think its fine that there using DTS-MA, but there still using PCM also https://www.blu-ray.com/movies/movies.php?id=1189

as long as they dont go exclusive with TrueHD.

Ok so what does this come down to? All three advanced audio codecs are lossless but some are more lossless than others?

Nope i didn't say that, but they are mixed differently. except for PCM which is raw.

Mixed differently? Using a codec isn't the same as mixing a movie. It's a compression technique applied to the uncompressed source. Like flac being applied to wav. Nothing gets changed.

Blu-ray.com has not updated there site. The Prince of Caspian will be 7.1 DTS-HD MA per the Disney site. You will not see PCM mostly at all for now on from any studio. No reason to take up all the space if you can use DTHD or DTS-HD MA.

They've been using lossless and uncompressed codecs this entire time... What's different?

My ears consistently hear what sounds "better" from straight PCM tracks... though obviously without a direct a/b it's impossible to say anything definitive.

If compression is needed for space, I prefer DTS-HD MA as DTS doesn't include dialog normalization and other "features" that re-process the audio waveform.

Actually, if I remember properly, DTS does have the option to include that metadata. And most times, DTS tracks are 4db louder than normal.

DaViD Boulet · 11-11-2008, 01:48 AM

Dialog Normalization doesn't increase level. It only decreases it via digital volume control by a prescribed decibel level set by the flag.

DN can't be used to raise level because the circuit has to assume that the recording level of the audio might have dynamic peaks that reach the maximum headroom.

Dubstar · 11-11-2008, 02:25 AM

well they aint Warner that's for sure....

owa · 11-11-2008, 02:32 AM

I'm fine with PCM, TrueHD or DTS-HD MA so it doesn't matter to me which one Disney uses. As long as lossless is used, it's all good.

I didn't say it was the DialNorm that increased the level, I said the tracks are 4db louder than normal. Which is why most THX certifed recievers use DialNorm @ -4db when a DTS track is being decoded.

davcole · 11-11-2008, 03:32 AM

I'm all in favor of them switching to dts-ma if that is their plan. The more space and bandwidth you save, the more opportunity to add extra material and it saves you having a separate legacy codec.

I've been of the opinion that all 3 lossless solutions give the same resolution, however to my ears PCM has a smoothness that Truehd lacks. With dts-ma, I hear the smoothness that I equate with PCM.

I ment when a studio does the mixing using one of the codecs, for example dolby uses dialnorm. i know what it is, and why they use it http://www.hometheaterhifi.com/volum...on-6-2000.html but why would they alter the sound?

also i heard sony turns off dial norm on there movies?

Wow i didn't know that, why are these studios moving away from PCM? blu-ray has the space for it obviously so why not use it.
dont call it wasted space cause if its being used its in no way wasted.

micks_address · 11-11-2008, 08:15 AM

i've read in the past thats its 'harder' to do seamless branching with PCM tracks... and that was one of the reasons Sony was moving away from PCM to Dolby TrueHD
