TrueHD vs DD on the Dark Knight

Random thoughts: Before I bought into bluray, I was excited as anyone about the lossless formats. When I tried lossy vs lossless at first, I was disappointed. Admittedly, they were only the briefest of tests on a couple of titles. After that, I always figured that maybe I'll get something out of the lossless formats, but I wasn't going to compare anymore, and just select the best track available to me.

Now, TrueHD sometimes really bugs me. It can't be set as default as with MA (or maybe it can, but it usually isn't anyways). I never know whether the auto flagged DRC vs defeated DRC is supposed to be better. I don't know if dialnorm was too screwed up.

Anyways, so I played with the DRC settings, after a fellow consumer that I trust believed that this one had better surround envelopment with leaving the DRC on. While playing around, I decided to listen, for a good while in fact, the lossy version.

Man, just the dialogue alone was a huge difference.

Which leads me to ask: Why didn't I head such differences before with other titles?

1. Could it be that the other titles had mixes where lossless never really benefitted them, but DK did?

2. The difference in the quality of mixes on DK is greater than what exists on other titles?

3. I would expect that any title would offer the best mix they could for BOTH the lossy and lossless tracks, but is there a possibility that they either shafted the lossy track in order to promote lossless and all the necessary gear associated, or perhaps they just did not care to spend any time on the lossy track as they were too involved and wanted to give their TrueHD track the best care they could?


Its impossible to compare lossy vs lossless tracks precisely because the mixes are different. Correct?

Whether its solely dependent on the mix, or not, my opinion/viewpoint on the matter has shifted more greatly on the side of lossless codecs. This is definitely different about how I felt up to this point. Cheers.

In what respect was the dialogue better (clarity, volume etc)?

Thanks for your thoughts.

Thanks for your thoughts.
The lossy track could be described as muffled in comparison. That was really the easiest thing to differentiate, because well, actors speak during movies...

With the other effects, surround, etc, the lossless seemed to be more brilliant, clear, with more dynamic range, and I want to say a clearer, more believable and/or enjoyable soundstage. I have slightly less conviction with these listed characteristics, if only due to the nature of these things. (Dialogue is pretty easy for us to discriminate in terms of quality. We listen to each other talk every day of our lives, for better or worse! :p).

There is definitely a volume difference (about 10dB) with Warner's DD and Dolby TrueHD tracks. However, I find it interesting that you mentioned dialog. Warner uses the much loathed dialnorm which means one really has to crank the receiver/pre-pro volume to hear dialog, so that when something dramatic happens the listener's eardrums really notice. Now, dynamic range shouldn't matter with DD vs. DolbyTrueHD according to Filmmixer's AVS posts.

DRC is useful for people with crappy TV speakers that can't handle range (really just wide bursts of loudless) and people that need a steady volume because they live in apartments/condos or have someone asleep in a back or adjoining room. People with Blu-Ray players are acting like DRC is something new. However, nearly every modern DVD player has it. All of my upconverting DVD players have it. It's not a HD only thing.


Josten, you're not noticing tighter, deeper bass with the lossless track or greater details (especially with surrounds)?

The differences are real. I do like what the lossless tracks have to offer. As for The Dark Knight, I noticed the dialog differences too, but also the explosions seems better in True HD, and the computer gun tests sound punchier.

I just had simlar experince while viewing Ironman. I plugged it into my player an just hit play without noticing the incoming signal was DD and watched for several minutes, in my usual manner. Shortly after the ambush scene were Stark is taken captive, I realized that the incoming signal was not true hd and I quickly reset the playback in lossless, and there was a difference! AAMOF I have finnaly got around to watching both Ironman & TDK this weekend I thoroughly enjoyed those films. IMO lossless audio appears to put more emphasis on the surrounds & dialogue which heightens my entire experience. Heh... next movie on my to do list is Eagle Eye.

Just to clear things regarding my above post! My first few BR's were all mastered in DTS HD-MA and therefore I had my panny set up to only bitstream DTS... duh:eek:. As for TDK the True HD track really does localize and enhanced the overall dialogue IMO over that of DD.:)
