Games to use Compressed Lossless eventually?

Its sad but very true, they also watch these dvd's through a mono tv speaker. Surround sound to the average person means 5 speakers each with sound.

PQ is way more important.. but I wont complain about getting better audio.. That would just be sweeeet

In the menu options for Uncharted Drake's Fortune, there is an option for Linear PCM 5.1 and Linear PCM 7.1

no, because Devil May Cry 4 show up as Dolby Digital, not PCM

Nope. Not in N.A.

Uncharted lists Dolby etc but not the specifics.

Resistance has the THX logo as required .. but not the channels etc...

Sucks eh.

since games vary in thier audio, i think they should include what it is on the back along with resolution

yeah definitely, uncharted and LAIR are the only ones ive seen where the packaging lists Linear PCM 5.1/7.1 as an option

edit:forgot LAIR

[Luis_A51]

I know there are plenty of games with PCM (all exclusives AFAIK)

None except for LAIR and Uncharted mention it on the box, and only a few have it in the option menu.

I dont think the PS3 does internal decoding for games. For example, every time I play DMC4 it shows dolby digital. Therefore its not decoding. I think it defaults to whatever the highest setting you have the the Audio Options menu. It has nothing to do with the bitstream/PCM option thats in the BLURAY section.

Is there really that much difference between PCM and Uncompressed PCM as far as games go? Since the PS3 (during gaming) doesnt decode, wouldnt that mean it would have to be uncompressed PCM?

I think games that show "PCM" on a receiver have a DD or DTS track, plus an uncompressed PCM track

[un4gvn94538]

as an example: today i put in UT3, i leave everthing checked with pcm and i get multi channel. i unselect 5.1 and 7.1 pcm and get dd bitstreamed since its showing on my receiver. you would think you would have an option like bd movies since i have read some are using 2 ch pcm with optical because they dont have hdmi.

But the lossless audio is exclusive

it seems lke it just switches to a seperate PCM track automatically as long as you have it checked. I think they assume you would want the uncompressed track vs. lossy is your system can do it. I've never even bothered with the DTS track on Burnout, that's for sure....the PCM track is great

Yeah thats what I think.

Like I said, I dont think the PS3 decodes during gameplay. It bitstreams the highest quality audio format you select in the Audio Options menu by default, unless theres a menu in the game that allows you to change that. Therefore, if it doesnt decode, then the PCM would have to be uncompressed, by definition. AFAIK of course.

Technically I meant that all exclusives have PCM, not that all the games with PCM were exclusive. But I might be wrong there too

either case i firmly believe if i can use thx select 2 to matrix 5.1 pcm to 7.1 with blus, then i should be able to do the same for games without having to deselect anything and matrixing the lossy track

[Pelican170]

Well, my question is, if i LPCM sound to my reciever and it always shows Multichannel PCM, how can i ever really know if its playing a lossy track or not? Besides just listening to it. Games should definately have an audio selection like movies if they are using uncompressed sound...

All these posts and none has gotten to the core of the issue. Since this discussion is about lossless, let's take a movie soundtrack analogy.

In the studio, a movie soundtrack gets mixed by the sound mixer. Three basic elements make the soundtrack: dialog, sound effects (or foley sound) and music. The mixer combines all three together to make the final mix, varying levels depending on the situation of the mix. Once the final mix is approved by the director, the soundtrack is then compressed losslessly for digital presentation or Imax, or it is compressed into DD, DTS or SDDS to be printed along the 35mm copies.

In a game, the PS3 is the mixer. The sound mixing module of the game assembles the dialogue, sound effects and music from its compressed files. Then depending on the setting, it will either send it out losslessly or compressed as DD/DTS. So if you already have a HDMI-based sound system, you're getting lossless sound.

Why do some games default to DD/DTS? Ask the game studios why they don't program according to the PS3 audio setting.

some guy on the first page said it was not possible or something like that as far as lossless sound, but I dont understand. if they can use DD, why cant they use TrueHD. damn the game companies.
