question about quality of sound??

[DannyTalent]

hi is DTS-HD Master Audio 5.1 the best quality of sound you can get on a blu ray?

I ask this question because well some films i have are just not the same sound of other one?

I have a samsung BD p1500 to a sony dav dz260 which is about all i can afford, i am using optical for the sound and i remember when i first bought the player i was told it would give me the best sound possible with the Dav system.

anyways is the DTS-HD Master Audio 5.1 the best sound?

dts-HD Master Audio and Dolby TrueHD are both lossless formats, meaning they produce exact copies of the source soundtrack. That's the best you can get. Uncompressed PCM soundtracks are also exact copies of the source material and are equal in quality to dts-MA and TrueHD.

Optical cannot carry TrueHD, dts-MA, or uncompressed multichannel PCM. HDMI is required for lossless formats. With optical, you are limited to the lossy DTS core or Dolby Digital 5.1. However, those legacy codecs are less compressed on Blu than they are on DVD and they rival lossless in quality. So, your current setup using optical from a BD-P1500 will give you great sound.

no, its the same as Dolby-HD and PCM. some prefer it, but theoretically they're all the same.

[onemorechance]

it all depends on how the transfer is made..you could have some PCMS that are rocking and others that suck..it all depends..but when transferred perfectly..they are ll the same

[solarrdadd]

the only thing that changes within this realm of lossless audio is the frequency and bit rate in which it's recorded/mastered, i.e. 48khz/16bit, 96khz/24bit, 192khz/24bit those are typical examples, the higher the freq & bit rate the more information is contained in the recording. the 192khz/24bit is really rare, however, the 96khz/24bit to me is the sweet spot!

Ya it is a good sound on some films, is that because of the films different sound tracks, such as the film Taken or Wall.e which has DTS MA sound amazing on my system and then Troy which says has PCM 5.1 does not sound as good?

when i say sound amazing, literally all my speakers are working at their best, rather then just giving out a quiet sound now and then.

Exactly. Lossless is lossless, but the total quality will depend on the quality of the master and the mix. Keep in mind, as a previous poster said, you are not getting lossless sound with an optical cable. Lossless can only come from HDMI or multichannel analog connections. I noted that your system has HDMI, so unless it is an older video only HDMI connection, that is what you should be using to get lossless sound. With optical, you get the core lossy tracks from lossless soundtracks from Dolby and DTS and 2 channel PCM from multichannel PCM tracks, that is all that optical can handle.

If you are using optical, then a 5.1 PCM soundtrack will be downmixed to stereo, which would explain the lack of surround sound. Optical supports a maximum of two channels of PCM.

yes..... And I'm guessing this is what the OP is experiencing....

Go to Monoprice.com and pick up an HDMI cable.

iv got a hdmi cable going to my tv from the bluray, but there is no in and out on my dav system, so therefore the best i can use is the optical no?

Yes. Troy has a DD 5.1 track as well. Try it instead of PCM. The DD track is encoded at 640kbps and you should get excellent surround sound from it.

how would i change from the pcm to the dd 5.1?

I have Troy on BD, and I remember the 5.1 DD sounding pretty good for a lossy track. You should be able to go into the audio setup section of the disc's menu and select DD 5.1 instead of PCM.

okay ill give it a go now, so i am going to guess DD 5.1 sounds better on my setup then PCM because i am using optical?

[DannyTalent]

i dunno if it matters but i have just relised that the sound is different, it says on the back dolby true hd 5.1 or dolby digital 5.1. Mine is an English version? and the sound isnt that good compared to other films of mine?

big parts of the film such as the beginning when they first go to fight the sound isnt that loud, as loud as you would think?

on my dav system, some films are really really loud at 25, when troy is not that loud at 29?

That's most likely a difference in the soundtrack mixes themselves. A bad mix is a bad mix no matter what format is used to put in on a disc. There are lots of great PCM and TrueHD soundtracks and there are also weak dts-MA soundtracks.

Two factors come into play here. First, the recordings themselves are not done at the same loudness. Second, dialnorm adjustments on Dolby tracks often means their overall loudness is reduced by about 4dB. Simply turn up the volume a little more on your sound system.

With DD 5.1 over optical, you get discrete six channel surround sound. With PCM over optical, you only get stereo because the S/PDIF protocol is limited to two channels of PCM. The quality of the audio is actually better with PCM. But, most people prefer to get discrete 5.1 instead of stereo.

Okay thanks for the help, the troy BD on my system is not very good, the sound is probably the worst sounding BD i got, im watching Die Hard 4 atm and the sound is amazing, that is DTS Hd master audio. So really it is just where the films themselves where recorded differently?

if i did have a decent setup and i could play the Troy BD with the uncompressed pcm? would it sound as good as die hard 4?

Beats me. Here's the point: it all depends on whether the soundtrack was mixed to your liking. It has little or nothing to do with the codec used to store it on the disc. If you like Die Hard 4 with its dts-MA track, then you'll like it with a PCM track or a TrueHD track. They're all the same. Of course, you're not hearing the dts-MA track over optical anyway. You're getting the DTS core, a lossy version of the lossless Master Audio track. But, as I mentioned in my first post, the high bitrates used for lossy DTS and DD 5.1 on Blu-ray means they rival lossless.

okay i got ya, so what i need is a receiver which has DTS HD Master Audio, is there a big difference in what i have now? also my BD player says on it Dolby True HD so from that i wouldnt be able to get DTS HD Master Audio?

thats the problem. distinguishing what we WANT compared to what we NEED.

ive seen others go gaga over trying to get the AVR to display DTS-MA or what not, others prefer sound quality.

if your receiver has multichannel analogs out as well as your Blu-ray player, you should be just fine receiving the LPCM signals. But it also depends on the quality of DAC's found in both the receiver and/or the player as another variable in the loop.

I think Bislander mentioned that in one of his previous post, with me echoing his sentiments.
