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.

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.

[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.

I've never experienced that as long as they were both sent over HDMI. I have heard there may be a difference when comparing HDMI versus analog due to bass management and DAC's in the player.

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.

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.

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

My Sony receiver is very much like yours...it accepts lpcm can not decode DD HD or DTS HD MA. When I set up my LG BD player the settings are set to lpcm 7.1. The player is doing the decoding not the receiver. If I use a pass through or DTS re-encode their is a noticeably difference or lack of back round noises ie... birds, wind or leaves blowing in the wind and the speakers have a much more fuller or enveloping sound to them when set to lpcm. You should get HD audio (48hkz) with your receiver if you set your PS3 to lpcm out and your receiver is set to DEC auto in it's set up menu (option 5 Audio). However, I noticed you my not have all five speakers and a sub to get 5.1 output. You need at least a 5.1 configuration. What are your surrounds?

You may not "hear" a difference from lpcm to bitstream due to a 3.1 config. or your master volume is low. Try to turn up the master volume and you might hear a difference.

Good Luck
