cannot tell AQ difference..

[Lt. Aldo Raine]

so i have a ps3 slim, hooked up to a sony str dg720 by hdmi
if u kno this receiver, then u know it does not decode hd audio, but accepts lpcm
and here is the thing, i cannot tell the sound difference from when i send the audio lpcm, from bitstreaming
wont the AQ be abit less if i send it bistream? cuz then i'll only be getting the core track and not the lossless? but i don't hear i noticeable difference..
is something wrong, am i maybe not actually getting the true lossless track at all?
im a little confused here

when playing a movie on the ps3, you can check to see if your sending out decoded lossless audio by pressing (i don't remember) either start or select on the controller and onscreen should say what the codec is. since you need to go into the menu of the player under audio and tell it to do the decoding onboard in which case you'll be streaming LPCM out to your receiver.
at the receiver it should say something like "multichannel or LPCM or both" i don't know and you may also need to press display on the receiver to see what is being sent in on that hdmi input.

what you will get with lossless is more information, more dynamic range of sound information that you can't get with lossy core codecs.

thanx, but i know all of that info
i make sure that i have the lossless track clicked on
the front of the receiver says PCM when watching a blu ray, and if i switch to bitstream then it will say Dolby/DTS 3/2.1, so i know if the player or receiver is decoding and what it is
but i do not here a sound difference
sure i hear a sound difference if there is a normal dolby track and dolby true hd track on the same disc
but i dont hear a difference if im playing the lossless track and i have it lpcm or bitstreamed
thats what i am saying is weird and i dont understand

[solarrdadd]

none of us can speak to what your ears hear. we all have very different sonic opinions of things. i can only tell you that there is many times the information in lossless then lossy, hence the size difference of their files. same for 480p and 1080p more information. other than that, no one can tell you "what you should be hearing" i will say i believe that lossless codecs, when done well will appear to sound better due to the higher depth of sonic field; whether everyone can hear it is another story. i believe i can hear the difference, but, i won't swear on a stack of bibles. i just like the idea of knowing that i'm getting all of the information the folks who made it wanted me to have the potential to hear.

best of luck.

From what I understand (and people can correct me if I'm wrong) is that there is no difference between bitstreaming and lpcm.

[HiDefRev]

The new PS3 slim can send lossless audio via bitstreaming OR LPCM ( something the old PS3 could NOT do ). There should be NO DIFFERENCE in the sound you are hearing, whether bitstreaming or LPCM.

yes i understand that, if i had a better receiver that can decode hd, BUT, my receiver does not decode DTS HD MA or Dolby True HD.. only can Accept LPCM.
so shouldnt there be a sound difference between lpcm and bitstreaming then?

Technically, there is a difference. However, some people say the difference between the core DTS-HD stream (1.5mbps) and a LPCM stream is hard to hear in a non-test environment. Everyone's ears are different.

for me the difference between lossy and lossless was subtle. No major changes in how the soundtrack sounded but i noticed a lot of subtle differences in the soundtrack, like extra background noises etc. Everyones ears will hear different things though

yea ive heard this before, but there still wasnt a difference with dolby tru hd tracks either

thanx for the feed back guys

Both DD 5.1 and the DTS core are encoded at higher bitrates on BD than on DVD and they sound better as a result. I rarely find the lossless outputs better than these less compressed lossy versions on Blu-ray. But, there are exceptions. For example, the PCM track on Black Hawk Down sounds appreciably better to me than the 640 kbps DD 5.1 track.

[Hoser59]

From your signature it looks like you only have a 3 channel setup, is this correct (I don't see any surround speakers mentioned)? I have the same Sony receiver as you and when I made the jump to Full HD I noticed the majority of improvements in the surround channels, not the front three. If you do have a full set up then it might just be your ears. The first movie I used to compare was Master and Commander. It sounded good with just the core but the difference was obvious between the two. I could hear every splinter of wood tear off the ship when a cannon ball tore through it.

[tilallr1]

Personally upgraded my receiver to HD after purchasing a PS3 and expected a huge sound quality jump. That did not happen, but there is a difference in the sound field as said earlier. Funny though that after years of listening to lossless I have finally developed an ear for it. There have been times that I will begin watching a movie (Sometimes without going thru the menu) and realize about a few minutes in that the sound quality is crappy. Which causes me to go into the menu system to realize it's set to lossy (Warner titles usually). When I switch it over to lossless, I notice an immediate improvement.

P.S. I did however notice a much larger sound improvement by upgrading my speakers. That was almost a night and day difference.

Different receivers and equipment vary for sound no matter if it accepts it or not. I had an older Elite receiver that had 7.1 analog inputs as opposed to HDMI and played the True HD and DTS-MA tracks when selected. I still felt like something was missing so I purchased a new Elite receiver with HDMI and all I can say is what a difference ! So what I'm saying is that your problem is with equipment not being up to par so that's why you don't hear a difference.

The only difference I know of is that bitstreaming audio makes it louder, I tried bitstreaming T2 I only turned my receiver up to about -40 with PCM I almost had it turned up to -20. That is the only difference I know of.

only if the core track is DTS-HD or True-HD.

if the core track is DTS-HD or True-HD: if you have it on LPCM you'll output DTS-HD/True-HD, if you have it on bitstream you'll output DTS/DD

if the core track is PCM: you get PCM sent out of the PS3, regardless of whether its set to PCM or bitstream

[lojack1976]

Whether the PS3 decodes or the receiver decodes you will get the same result. Some people prefer the ability to bitstream to allow their receiver to decode thinking that it will do a superior job, but I have two setups with one bitstreaming and one with the PS3 decoding and there is no difference other than the characteristics of the equipment.

The receivers differ so that will influence the sound as well as having different speakers. Of course I've swapped things around so I've heard material on my main speakers using both receivers and I've used both my PS3 and my standalone on both and there is absolutely no loss in quality in either scenario.

The best thing about bitstreaming is seeing the logo light up on the receiver. LOL. Of course having the flexibility to do both is nice since you may own a standalone that decodes True HD but only bitstreams DTS Master Audio which is the case with my standalone.

Apples and oranges, there. Not apples and apples. When using analog, the player does the digital processing (such as bass management) and the digital-analog conversion. With digital, all of that happens in the receiver. So, you were never comparing PCM vs. bitstream in the first place. And, when you upgraded your receiver, you changed all sorts of things which have nothing to do with PCM vs. bitstream.

Then I guess I misunderstood the question in the first place.

iceman_mw21,

The biggest difference I noticed, after getting HD sound, is in the background, such as a TV, people talking, whispering, creaking floors or wind blowing. They usually come from the surrounds.

What is the answer to the question Hoser59 asked? Do you have surrounds or just 3 speakers up front? If you don't have surrounds that is probably why there is no difference. That is probably why your only hearing the core/ big sounds. You're not getting the fine details delivered by the surrounds.
