TrueHD & DTS HD MSTR
- Thread starter Clipsey

The best way to think about it is that DD has become TrueHD and DTS has become DTS-MA.
They do use different decoding methods, but as already stated, both are lossless, so in theory should sound the same.
Note that most BD films use DTS-MA.
The key practical differences are if you use a legacy AV amp that doesn't support HD audio and choose to use an SPDIF connection. In that case, each lossless medium will output it's "core" signal. For TrueHD, that means a DD signal at 640bps. For DTS-MA, that means a DTS signal at 1500bps. So for legacy AV amp users, disks with DTS-MA audio encoding is a GOOD thing.

Well PCM would mean the source device is doing the decoding instead of your amp... unless your source is PCM to start with?
It's probably the fact TrueHD at least has some sort of volume levelling or are mastered differently. But LOSSLESS is LOSSLESS.

I think from my setup that DTS-MA gives it a bit more punch and base to certain movies. TrueHD is only enhancing and making it louder?
TrueHD enhancing what?
the design of the soundtrack itself makes more difference than whether its TrueHD or DTS-HD MSTR
Some soundtracks on both formats sound ok but dont surprise as you hope/expect them to - while other soundtracks (of both formats) can blow your ears off
Unless you have a very high end source and low end amp (not sure why but its possible) - its always preferable to have the amp do the decoding (likely to be more accurate), the amp was built to do the job, majority of sources arent built to do it, but its a tacked on extra. This is (in my Humble opinion) why PCM is the least prefered option
Obviously there are some films with PCM formatted tracks which may well sound better than other True Hd/DTS ones, but this is pretty rare

What does my head in with these HD formats is how unbalanced they always seem to be. I don't know if it's because they are mixed for a cinema or something, but I always find that the speech volume is low and the sound effects are really loud, so I have to constantly raise and lower the volume throughout a movie. I tried putting up the center speaker volume but it doesn't really make a difference. Whenever an action scene comes on, the whole lounge is just filled with the sound of explosions/crashing and whatnot and I have to quickly turn the sound down.

Yes i notice this as well. What speakers do you have ?
I find that if i put the volume right down so that i can only just hear the voices from the center speaker, then the sound effects are still loud but not too loud. But if i put the voices up to a level that is above that. Then the explosions are just too loud for me. Some sources are worst than others.

I happen to love that
I have always been too considerate with the neighbours, think it was my parents fault for always making me be quiet all the time.
I have these great speakers but i watch most of my stuff through headphones anyway
Funnily enough, explosions and things are louder than people talking. It's really as simple as that, you can destroy the dynamics of the film by enabling range compression or maybe try your amps night mode.

Luckily don't have to worry about that, although I'm sure the SVS sub rumbles the entire sub-division
Got this all working from .iso and in PowerDVD.
Can you get this working from .mkv and in XBMC?
Not quite. some are more lossless than others. See here.

To be honest there are quite a few PCM soundtracks,especially on some of the earlier released blu ray discs. Some in my collection include Hellboy,Underworld,The Pirates Of The Carribean Trilogy,James Bond Casino Royale,Apocalypto and others that escape me.
I always set my blu ray player to bitstream the audio and allow the 875 to do the decoding.
I don't really see (well hear really) how PCM,DolbyTrue HD or DTS-HD can really sound any different as they are essentially exactly the same thing,the only difference being that DolbyHD and DTS-HD are compressed to save disc space where as PCM isn't,once the amp has decoded the compressed formats we are then hearing uncompressed PCM,are we not? Any audible differences must surely be my imagination,maybe the BK Monolith sitting in the corner has cooked my ear drums up! Ahhhh! My tinnitus! PLEASE BE QUIET!
