DVD audio vs Blu Ray audio.

[Justin3v06]

I was watching a movie recently in a home theater and did a comparision test between Dvd and Bluray. I started by playing the same movie (pearl Harbor) First on Blu Ray and then next on Dvd. It seemed that i had to turn the system up a lot louder on the blu ray movie than the Dvd and the audio was louder and somewhat clearer on the DVD. Thinking this was a fluke i then tried the Matrix on DVD and then on HD DVD and had the same result.

has anyone else tried this? I was using the LGBH200 running through an Onkyo905 receiver hooked up with an HDMI 1.3 cable.

I don't know what the problem is but there's something wrong with that picture. It depends also on the audio soundtrack on each disc. If you were to play a BD that supports DTS MA, Dolby True HD, Uncompressed, etc., then you would hear the difference and would have to turn down the volume by a large margin. I believe Pearl Harbor only supports Dolby Digital because it was made when BD first arrived. The movie studios didn't take the time to add advanced audio due to the format war.

I can sorta relate to this, i notice with most of my DVD's i hear alot more activity in the rear speakers as opposed to blu-ray, in saying that the bass i have experienced on blu-ray is a hell of a lot better

I agree. I made the same observation with both HD-DVD and blu-ray discs. However, after i did some playing around with certain settings, I realized that DD and DTS (lossy) tracks had the "midnight" mode on, which reduces the dynamic range. Many players have the lossy codecs set this way by the factory. The result is that loud sounds and subltle sounds sound the same at pretty much all volumes so u hear dialogue and explosions at clear and even levels at all times.

Lossless audio, on the other hand, wasn't set with any type of dynamic range modification. Which means that when the volume is turned up loud enough for you to hear dialogue, any other sounds i heard were relative to a verbal conversation. In a way, this is good because it's more life-like. An explosion while u are talking is gonna dominate dialogue. The drawback is that sound this accurate is scary! because the director of the film intended to create that effect.

I can assure u that if u watch No Country for Old Men, and watch the last scene with LPCM selected instead of DD, you'll be in for a surprise!

Hope that makes sense

yeah its all about dynamic range... your DVD tracks may seem louder but thats because they dont have the range... if they want one thing to be loud, everything has to be pretty loud... BD is much better because you get normal talking volume dialog and then huge, crackling explosions and realistic gunshots

WRONG! Disney AKA BVHE hasn't put a title out in anything but lossless.

I'm not sure which movie studios you're thinking of, because Disney, Sony and Fox have supported lossless audio on all titles since day one.

Also, you will find that the (audio) imaging is way more defined in Blu.

Whereas you will most definitley hear sound swirling all around you in a DvD, you will NOW hear things stop and hand to the front left (as an example) just inches from your face and pan with such depth and accuracy.

It's freaky sometimes.

Get deeper into it...you'll see.

Have fun and catch some air off that,

Anyone that is thinking standard audio from any dvd is beating any Blu-ray audio has something wrong in their setup. It's that simple. Always read the stickies available here on how to maximize your audio experience.

I haven't experience this at all.. definitely the other way around. Although DVD's with DTS surround sound very good compared to blu-ray, and is a lot better than DD..

[PanasonicPlasmaMan]

The difference is huge.. I recently rented Underworld on Blu Ray (i own it on DVD) and the difference is huge i wa bleeding out of my ears with the PCM 5.1 as opposed to the dolby digital 5.1.. You probably have something setup wrong because it makes a world of difference

Underworld in the beginning when everyone is shooting rules in PCM....

Kate isn't bad either..

[hagar852]

Try the end of the new rambo if you want to make your ears bleed...

20 min of a 50 cal machine gun firing!! in 7.1 DTS-HD

[Devildog151]

I've found that the best way to test this is by playing Underworld unrated on Blu-ray. At the beginning where kate is talking and it is raining bring up the pop-up menu and while the movie is playing you can change from Dolby digital to LPCM and trust me you'll notice a huge difference. It seems like the rain envelops the room and Kate moved closer to the mic and her voice becomes less muffled. Check your settings. I always notice Lossless to be louder and more defined.

yeah that was sweet to..

[Justin3v06]

I have recently tried this on a lower budget system and the results although still present, arent as noticeable. The original test system is a very high end dedicated theater room.


We recently tried the test again with 4 to 5 people in the room and they all came up with the same conclusion. The dvd Audio Track was noticeably more theater like. Now we did notice more activity on the rear audio tracks in the back of the room, on blu ray as well as clarity but it seemed to lose its punch on the LFE channel and sub frequencies.

The seat shakers were not as noticeable on the bluray track as well, in which they were also hooked up to the LFE channel through a secondary amp.

When we played the lobby scene on the Matrix through DVD it feels like someone is punching you in the chest when the guns are going off, HD dvd we had to boost the volume quite a bit more, and even then we didn't have the same result but yet the little sounds were a little more pronounced than the dvd.

I have always been a fan of the HD format and am som ewhat disappointed by these results. Tommrow i will list the settings and see if anyone has any suggestions.

Thanks Guys!

I would try picking a BD, and switching between different audio options with the same disc... The new Rambo should give your LFE a workout. Or try Top Gun, my whole house was shaking, and I couldn't get that with the DVD.

Settings and equipment would probably help solve if there really is a problem too

[zweet77]

I looked up your player and it does not look like it can bitstream or decode hi def audio that could be part of the problem but still it should sound the same what does your 905 say when you think it is set to hi def audio?

[BigBluu]

what about non-hd audio codecs (dd/dts) on a blu-ray? i watched ocean's 13 last night. it didn't have an hd audio soundtrack so had to settle for dolby digital. i initially had my ps3 set to pcm the audio to my v663, but i really had to crank up the volume more than usual to hear everything. i then switched it to bitstream the audio. it was slightly better, but still nowhere near dtshd-ma or truedhd. is this how it's supposed to be with non-hd audio on a blu-ray?

Maybe its cause your still using a HD DVD player, The Bluray gods cant be blessing you, your commiting blasphemy!! lol
