My question is: does Blu-ray 1 sound better than Blu-ray 2 when encoded with a setup capable of lossless formats? Or is there no difference once they are both encoded?

If this is the wrong place to ask, please put my question into the right area of the forum.



Lossless audio codecs are variable bit rate.. you cannot encode the way you are suggesting...

The codec uses as much data as needed to recreate an exact reproduction of the PCM that was fed into the encoder.

It isn't user selectable.

Sorry for me causing misunderstandings, I should have writen average bitrate...

...To give it an practical example: Do the DTS HD-Master tracks of those two BDs being compared here: http://www.dvdbeaver.com/film2/DVDRe...er_blu-ray.htm differ in their "quality"?

If NOT, is the reason that once the lossless track is encoded the two Master tracks are identical?

SORRY for the two posts, but I could not post the "Beaver" link in my third post.

Like FM said, the codec's job to recreate the original PCM track, if there is a difference between the 2 MA tracks by bitrate or perceived quality, it has to do with the same difference between the sources.The higher bit rate MA track was probably sourced from a higher bit word, or higher sampling rate PCM master, hence the need for higher average bit rate to recreate that source.

Thank you very much for the answer!

Two questions stay left:
1) What is a higher bit word?
2) If I come across two different bitrates of two Master tracks from the same movie (like in the Beaver review) does that mean there must be a quality difference because the source material alredy had that difference? Or can it be that the lower bitrate Master track is just more "efficient" in reducing the size of the original PCM?

Haven't had a chance to watch the full film, but scanning around MINORITY REPORT, it's sure sounding like a reference title.

1, bit word: should have said bit depth. 16bit 20 bit 24bit etc... the higher that number the higher the total size of the file will be.
2,The difference is always reflected on the source, the codec provides roughly a 2-1 compression rate regardless of the original size, so it's efficiency remains the same.

Michael Jackson's This is It (DTS HD MA) Tier 0

Sound: Tier Reference
Performance: Tier 1
Surround mix: Tier 0


The goods are the sound quality here, which is quiet surprising since this is a rehearsal not an actual concert.I was focusing here mostly on the instruments not the vocals which I rated mostly with "performance".Detail of all instruments are excellent provided this was a live setting. Dynamics were good especially since this is pop music. The vocal performances by MJ was rather "casual" it was obvious he didn't gave his all on this, and probably he was saving that for the actual tour, however since that never happened, this is what we left with.
The mix was how I like concerts to be mixed, mostly from the audience perspective not from the stage, with a little extra thrown in with a various production fx sounds.
All in all a very good effort here, worth to check out if you're at least remotely a Jackson fan.

@thehun: Thanks for all the infos!

Now: the movie which - to me - had one of the most overwhelming sound designs is "Vinyan". Go for the German BD (http://www.amazon.de/Vinyan-Blu-ray-...3325866&sr=1-2) and turn the volume of your setup really high before you start the movie. I'll never forget my fist time experiencing that

But it could be B-locked. If anyone is interested, levae a message here and I will check this out in a few days...

Porcupine Tree: Anesthetize (DTS HD MA) Reference

Sound: Reference
Performance: Reference
Surround mix: Tier 0


This is a great concert and and a must for PT fans like myself.
Sound quality is just superb much like the band's MCH DVD-As are.
All instruments come across clear with all the details they deserve.The drum kit is especially noteworthy.The performance is top notch as well. The only issue I had is with some of Steven Wilson's vocals, to be more precise with how it was mixed. On several occasions his vocals were rather buried into the mix, and since Wilson mixed the entire audio, it's hard to figure out what was the motivation behind it. Other then that one can only rave about this disc.

Road to Perdition (DTS-HD MA) Reference

I can't really think of a "demo worthy" scene as most reference titles have but everything about this soundtrack is perfection. EVERYTHING. PERFECT. Dialogue crystal clear. The score. Wow. Amazing score and it this tonal quality that isn't surpassed by very much. I was hit right off the bat during the title sequence with some gorgeous strings. I could have just closed my eyes and listened to that for 2 hours. Some real good LFE support during gunfire. It had some authority which it should.
It was fun to revisit this fine movie for the first time since it's DVD release.

I love this movie and I really heartened to see it get more respect thanks to this Blu-ray release. I'm eager to revisit it soon. Thomas Newman's score is achingly beautiful.

The Diplomat (DTS-MA 5.1) - Tier 3

Clear dialogue. Surround use for ambience, street scenes, office settings. Most of sound directed from the front with pretty good separation between left and right fronts. No LFE to speak of.

2:22 (DTS-MA 5.1) - Tier 3

Similar mix as The Diplomat except this one doesn't have any appreciable surround use.

Hot Tub Time Machine.....DTS-MA.....Tier 2

This movie didn't really have much surround use or LFE to speak of. The dialogue is clear with never a problem hearing anything.

Funny movie, but not funnier than The Hangover

Harry Brown (DTS-MA 5.1) - Tier 2

The dialect makes it sometimes difficult to understand what some of the actors are saying, not the fault of the mix. Some surround use for occasional effects, ambience. Minimal LFE.

I saw this last night and thought it was pretty decent sound-wise. Better than average with crystal-clear dialogue, a few discrete surround effects and nice LFE (almost always from music cues). Very appropriate mix considering the subject material.

Yeah, I thought it was fairly weak. Hardly any sound envelopment. Dialogue was fine as you mentioned.

Finally got around to watching.

Very impressive audio.

How about a more aggressive use of the low end?

Harry Brown (DTS-HD MA 5.1) Tier 1

The Joneses (DTS-HD MA 5.1) Tier 2

I can only imagine that the sound design budget was not a whole lot but what a nice job they did with what they had to work with. Ambience abounds here with discrete noises littering the soundstage. I could even hear the the fan humming in Harry's apartment. Gunshots were thunderous. Great job with the showdown sequence at the end. The sound really heightened the intensity during the last 20 minutes.
Very impressed with Harry Brown.

The Crazies

I didn't see any reviews on this one yet.

I was impressed! There is some excellent bass in this movie. The dynamic range is impressive, and there is very good use of the surrounds.

This is one of the better mixes that I've heard lately.

Be sure that you manually select the LPCM track, as the default is DD.

Tier Recommendation: 0

I watched this a while back and agree with your thoughts. How about that tractor scene for LFE!

Yes, that was the best bass scene in the film! It was sustained for quite a while too.
