Dts-hd master & lpcm

[Ashok Reddy]

Hai, lets talk about DTS HD-MASTER & LPCM...My opinion is DTS HD-MASTER is better than LPCM.. .csrini,venky,annayya,murali91,zombeaner,terminato r2,Daomen angel,.. Submit your opinion my dear friends, please please.......

May I ask why you think DTS HD MA is better than LPCM?

well what i think is LPCM is by NO WAY inferior(if not better) than dts hd ma because
1-LPCM is practically the raw soundtrack that the sound mixer mixed as it is....it is purely lossless , wheras,
DTS HD-MA is theoratically lossless but still some encoder to encode it into dts hd is used

so LPCM is by no means inferior to dts hd ma!!

[zombeaner]

To be honest, I think it depends on the disc. I've heard really great LPCM tracks, like those on Bhavani's discs, and I've heard really great DTS-HD tracks. There are some cases where even the Dolby Digital sounds better than the DTS-HD. Strange, but I've found one or two that way to my ears.

if original sound is sampled at 7.1 channel 192khz 24bit, then you can have dts-hd 7.1 channel 192khz 24bit encoded which is pretty as same as original sound. but it's no way for lpcm to have 7.1 channel 192khz 24bit used for blu-ray, so which is better? for the lower sampling rate and low data-precision for sound sampling, the fixed and constant bitrate of lpcm is equal to variable bitrate of dts-hd (losses audio).

personally speaking ......i think i havent heard any 192khz 7.1 soundtrack....!!! what i believe(correct me if iam wrong) that 192khz sampling rate exists only in 2 channel PCM and not in 7.1 channels....!

A normal hearing ear will not see/hear any difference between the two.
lot of folks have the hd audio decoders, meaning there are extra lights coming up on their receivers, which people feel their receivers worth the money spent.
And i still think it is all the speaker setup one has. From basic to midrange speakers, we should not hear any difference between the two.

[divyansh]

further any format whether dolby digital or dts or dolby true hd dts master audio any format is ultimately converted into PCM in our amplifier to provide signals to our speakers and logically speaking PCM should have an edge over dts hd and dolby true hd because it is used directly by amplifier without converting it into PCM but PCM track is not very common especially in INDIAN blu rays because it takes a lot of space and indian movies itself are quite long so there is no space to waste in PCM soundtrack as theoretically speaking dts hd also is bit by bit identical to PCM....! though my ears cannot distinguish the difference between the two and even if there is some microscopic difference of quality between the two....I DONT CARE....! :P

That is not correct, PCM (pulse code modulation) is a digital signal, which speakers cannot understand. The signal provided to a speaker is analog.

As for the original question by the OP, if done right, there ought to be no 'audible' difference between a LPCM track and a DTS-HD MA encode of the same source. Neither of the two is sonically better than the other, but considering the fact that it can provide the same quality level while taking up lesser space than a LPCM track, does give a practical edge to DTS-HD MA.

[annayya]

I personally prefer DTS HD Master audio on Blu-rays but I honestly cannot tell if it is better than LPCM.
LPCM is supposed to be the best audio possible becuase it is lossless original audio with no encoding/packing. From what I recall LPCM has limits for bit-rates though and DTS HD Master can have higher bit rates than LPCM but can it really be made better than the raw audio is the question. I would say yes, if a ripper can make a DVD quality better than the source then why can't DTS HD Master be better than the original if it is encoded properly/perfectly. LPCM is a waste of space.
DTS can go as far as 192kHz/24-bit while LPCM can only go upto 24-bit/96kHz. But how much can a human ear hear
Many Blu-rays have LPCM audio which are really good and if I don't look at my receiver screen I would not be able to tell what audio format it is.

This discussion will be like Dolby TrueHD vs. DTS HD Master
DTS HD Master and Dolby True HD both claim to be lossless too but they are compressed. Dolby is compressed a lot more than DTS but can deliver higher bit rates with smaller space. So the argument continues.
From my experience I feel like I can hear the DTS audio louder and more clear for low sounds than Dolby True HD.
I don't really care about LPCM because it occupies way too much space which can be used instead to make the video quality better.
So the answer is ... its more of a personal preference and my preference is DTS HD Master.

I also have an A/V receiver, so I guess it must be doing something hopefully to enhance the audio quality further.

It all comes down to how much space the authoring companies decide to use for the video because some occupy more than the others.
LPCM (highest space ... way too much)
DTS Master HD (medium ... I say perfect for Blu-rays)
Dolby True HD (must be used when the video is too long)

+1. But somehow I feel that DTSHDMA always sound a little louder than the LPCM and DTHD counterparts.

[GoodToGo]

There have been huge flame wars about DTS MA versus True HD. This is one classic example.

I really cant make the difference between DTS MA & LPCM. They both sound great. TrueHD, on the other hand, sucks ass.

no...no sanjay you got me wrong......what i mean is that the amplifiers understand the language of PCM.....dts hd ma and dolby true HD are all converted to PCM for further processing by amplifiers all this is ultimately converted into analogue signals that is given to the speakers (well my knowledge says this....again correct me if iam wrong...!)

[icyteddy]

DTS-MA is NOT better than LPCM or vice verse. But what I can tell you is my earlier blus that was release LPCM sounds sounded superior then some of my newer DTS-MA blus. When I say superior I mean, power, shaking, loud and clarity.

To me, lossless is lossless whether it is Dolby TrueHD, LPCM or DTS-MA, I judge on the way the studio pressed codecs and how it sounds on my HT.

DTS HD MA and PCM both support 192khz BUT IN 2 CHANNEL MODE ONLY
the fact is dts hd ma supports upto 96khz in 7.1 or 5.1 channels so there is no 5.1 or 7.1 PCM or DTS HD 192khz soundtrack ever.....!!!!

So what you are saying is Dark Knight, Transformers, Iron Man, Star Trek sounds weak???? They were all recorded in Dolby TrueHD. Sorry, but the titles I just mention are all demo quality to me and they sound superior to some of my DTS-MA blus.

[FreakMan]

to me lossless is lossless i have some blus with LPCM and DTS MA or LPCM and TrueHD and all sound the same too me.

There is no difference between the two: loseless data is loseless data!

for lpcm, it's no problem to have 22.2 channels like japanese labs did, but it's impossible for a blu-ray.
the audio bandwidth limitation (total max A/V bitrate excludes video bitrate) on blu-ray makes it no
chance to deliever lpcm 5.1 channels 192khz 24bit, but it's no problem for dts-hd ma. dts-hd ma does support 5.1 channels 192khz 24bit, or 7.1 channels 96khz 24bit.
5.1 channels 192khz 24bit lpcm, the bitrate 6x192000x24=27648000bps. for a 2-hour movie, the lpcm audio data would occupy around 25gigabytes, it would sacrifice video quality, don't even consider to bring up second video source simutaneously.
bigger container, bigger possibilities. under the current blu-ray specification, dts-hd ma 5.1 channels 192khz 24bit, or 7.1 channels 96khz 24bit would be the best of the best.

but is all this justified.......experts throughout the globe say its all the same.....pro B the moderator also just said lossless is lossless......no difference at all...! its all just a matter of choice....to us everything would sound just the same....!
