High-Def FAQ: Uncompressed vs. Lossless Audio

Joshu Zyber writes, "A couple of months ago, I wrote a column called Blu-ray and HD DVD Audio Explained that spelled out the basic functions, features, and differences among the various audio formats available on both High-Def disc types. In it, I explained that uncompressed PCM audio (as found on many Blu-rays) is an exact replication of the studio master, encoded on disc without compression, and that the lossless audio formats Dolby TrueHD and DTS-HD Master Audio are also bit-for-bit identical to the studio master once decoded. Doing the math, that should mean that a lossless track is also identical to an uncompressed track. Indeed, that is the case. However, some confusion remains as to whether an uncompressed track is actually better than a lossless one."

"The number of new audio formats on Blu-ray and HD DVD have caused a great deal of consumer confusion, especially with three separate formats (PCM, Dolby TrueHD, and DTS-HD Master Audio) all designed to accomplish the exact same goal -- a perfect replication of the movie's audio master. Apprehensions about lossless compression being inferior to an uncompressed version of the same soundtrack are not borne out by the facts. One methodology may have technical advantages over the other in terms of space savings, but the end result is the same whether the disc you buy has an uncompressed soundtrack or a lossless one. They're both equally good, so sit back and enjoy."

what a waste of time reading absolutely nothing but a person going in circles to justify D true-HD. Uncompressed carries the true track while the others drop what they call white noise to reduce the size of the track.

See your comment alone tells me you didn't read the article. Had you actually read it you would know thats not how this type of audio compression actually works.

What you said is basically how an mp3 works and to a lesser extent a wav. Perhaps next time a quick read would be better?

blackmagic6413d ago (Edited 6413d ago )

I think you are confusing the section on lossy compression with lossless compression. The whole point of lossless compression is being 'lossless' in other words identical to the original sample. As he points out in the article, the Linear PCM track or Lossless track could still be a downsampled 16 bit version of the master audio for various reasons from disc space issues to the Master not being a high enough quality to begin with as is the case in many older movies. Joshua Zyber is an exceptional columnist in the industry.

Who cares really... Sold my HD-A2 because I found out I'm getting a HD-A35 for Xmas. I have a Yamaha HTR-5940 AV Recever with an BIC Venturi DV62CLR-S 6.5” 2-Way Center Channel Speaker with two sets of
Bose Acoustimass 5 Series III Speakers for surround sound.

My system's hardly a sound setup that has me worried about the content of this post as if I know what it all means. All I no is I do not have $10,000 tower speakers etc as my set up is average.

green6414d ago (Edited 6414d ago )

same here.i will just get the HD-DVD add on for the 360.HD-DVD is cheep and i don't have the financial power yet to buy a PS3 because i want to watch HD movies.Its just storage space that is the difference.And i like hd-dvd feature of making dvd on one side and hd-dvd on the other so even if hd-dvd fails i wouldn't have lost much because my movies will still play on a regular DVD.

IGNFTW6414d ago

AND I CAN TELL YOU WITHOUT ANY HESITATION: BLU-RAY HAS BETTER AUDIO QUALITY.
PERIOD.

jaja14346414d ago

Playing Guitar Hero does not mean you make music. :)

jaja14346414d ago

Interesting read. I already learn most of that this semester when we studied compression techniques, but still very Interesting.

Now will this stop the "loss less is worse than..." crap that goes on in the HD vs BR threads?

ITR6414d ago

Read the new Harry Potter movie review on HD Digest..the reviewer basically says I can't tell the difference between the two.

I appreciate the article but this guy must be living in a delayed universe, The reputation was ruined 10+ years ago and hasn't recovered since. As such people have voted with their wallets and stopped buying Xbox products in large amounts.

YourMommySpoils2d ago

Their reputation was lost way before that. From the moment Microsoft said they entering the console business, we all knew it would be a downgrade.

Bathyj1d 23h ago (Edited 1d 23h ago )

That's not true at all the OG Xbox had drive and they had hunger and they wanted to accomplish something. It was a great console.

they didn't quite reach their goals and they gave up prematurely because they couldn't win. It was halfway through the Xbox 360 when kinect released and that was when they lost their way and we're a rudderless ship ever since

Agent751d 20h ago

In all fairness, Xbox had some great games with online play, Xbox 360 even better. Xbox consoles started to die with the Xbox One. Ditch consoles for the PC and PS.

YourMommySpoils1d 12h ago

@Bathyj hard to compute ay. Xbox was never better than a PC and that's all they ever were. A demo box. Doesn't get more true than that.

What reputation is this threatening exactly? 😂

Lightning773d ago

Rumors of Turn 10 being either shut down or hit with massive lay offs is on the horizon.

The issue is MS will do something right only to do something very, very wrong. And they do this what seems calculative at this point. Doesn't matter what they do the Investors and leadership want more and more money an endless bottomless pit of purr insatiable greed. A company that acts like it's broke or hurting is what really, really infuriates me. They've surpassed apple again well over 3 trillion who acts like they're a million dollar company is fk stupid. Pivots and changes for no reason and can't do things for more than a year with out a pivot or changing their metrics.

Christopher2d ago

That would be really bad since Phil just hyped up next year as a big Forza year at Summer Game Fest.

@christopher: “ That would be really bad since Phil just hyped up next year as a big Forza year at Summer Game Fest”
The key word big can be ether good or bad 🤷🏿only time can tell

DarXyde2d ago

First Forza being generated entirely via AI?

If any company would do it, it'd be them.

Nacho_Z2d ago

Isn't the point that it's irrelevant how profitable MS is, the suits have decided it's time that the Xbox division started making them money. Hence the layoffs, the pivots.

hennessey862d ago

That wouldn't surprise me, as motorsport has been heading down hill since the great number 4. Where as playground have consistently put out better games. I think the two studios will be merged under playground games banner.

As someone who has been gaming nearly as long as gaming has been around (since the early 70's), you'd think I'd be against this. Having grown up with all the major platforms and the whole notion of physical ownership... but I'm not. i embrace this as it is a revolutionary convenience. And one i know for a fact many (especially here) have not even given the fair chance to use. I get it... i was there too. But now i have a new outlook on it. It really is a hell of an option if you just want to play with no commitments. By no means am i saying this should replace traditional gaming, its an option. And one that people should look at optimistically as a way to compliment traditional gaming. There is room for both to thrive.

Zerobalance4d ago

I tend to use streaming on new games in GamePass. To see if I like the game. If I do, I'll download it for a better experience. It's so convenient & useful.

The 'Stop Killing Games' initiative is close to its final deadline

Ross Scott—also known as Accursed Farms on YouTube—has been fighting tooth and nail for almost a full year to help spearhead game preservation. Starting after it was announced that Ubisoft's The Crew would be shutting down, permanently ending support for the game, Scott launched the "Stop Killing Games" initiative.

That makes a twofold deadline for the Stop Killing Games initiative. Or, at least, one headed up by Scott: The UK petition, which ends July 14, and the EU Citizens' Initiative, which ends July 3.

M3talDiamond6d ago (Edited 6d ago )

If you live in the EU then Please sign this or our game ownership rights and game preservation is
at stake. I know there isnt much time left but please consider signing the petition

-Foxtrot5d ago

I never knew Ross Scott was doing this

I love Freemans Mind

Inverno5d ago (Edited 5d ago )

People whine and in the end don't do a thing. Then whine more when they get screwed some more smh. If this makes it then it'll be monumental for consumers. That Pirate software guy was no help either smh.

GazCBG5d ago

The EU Date is the 31st July not the 3rd
