I'm not very good at explaining these things.

That's a very good basic description IMO. I didn't understand those graphs before but now I do smile.gif
It's nice to see the max at each frequency for sure while the average may not hold much interest or as much interest.

I'm sure its been mentioned before but since I don't want to read through 365 pages of posts, how do you guys generate those graphs? The full movie ones.

Depends what you're looking for in a bass movie. One could have a couple scenes with loud peaks but the average is low. Another movie might not have really high peaks but a lot more scenes with LFE so the average is higher.

Its a bit complicated but here goes...

 

  • Load the movie into Eac3to and convert the audio to .wavs

C:\eac3to.exe C:\Moviefile.mkv C:\convertedaudio.wavs -no2ndpass

 

  • Load all the wavs into Audacity. Lower the gain by -20.2db for all channels EXCEPT LFE. After that is done, lower the LFE channel by -10.2db.

 

  • Select all tracks and go to Tracks-> Mix and Render. This will merge all the individual wavs to a mono file.

 

  • You want to add about 1min of silence to the beginning and end of the track by selecting Generate-> Silence. SpecLab for some reason doesn't render the end of the file so add a bit of silence to fix that problem.

 

  • Export your mono wav as a wav.

 

  • Download this config file and load it into speclab

http://data-bass.ipbhost.com/index.php?/topic/19-speclab-waterfall-scene-capture-tutorial/page-2#entry1828

 

  • Now you can render the wav into speclab by going to File-> Audio File and Streams-> Analyse Audio File (without DSP) and select your wav file that you created.

 

  • A new window should pop up with a bunch of different options. Under Speed (w/o replay), change this to fast.

 

  • Press ok and let it gooooooooooooooooo. Done!

I wonder if their lossless is the same as the theater mix or if they did the same thing as they did on Oz where they created a new 'near field' mix.

A near field mix? On the BD?

Interesting...
post #10957 of 16134
Yes. I've since read that the 7.1 remix can be a nearfield one without it being labeled as such. I wonder what they do to the bass in a nearfield that they don't do in the theatrical?
post #10958 of 16134
I've since found a movie that provided both the theatrical and the nearfield in lossless in the same amount of channels here http://bluray.highdefdigest.com/4121/thegame.html


Apparently the nearfield has a dynamic range reduced for 'home environments'. I've also read they can redo the EQ of the mix.

I'm starting to wonder if the big difference between STID and its predecessor is that they chose a 'nearfield' mix as their lossless mix of choice for the Blu Ray.

Also note how the reviewer noticed the volume as louder on the near field mix at the same volume level - this might give some more info towards explaining the 'harsher' mixes or clipping issues. IDK i leave it to you to muse over.

"The Conjuring" ...............Scarrrrrrrrrrrrry LFE eek.gif easy stroll to the 5 star list
post #10960 of 16134
I saw Gravity in IMAX 3D the other evening and man what a fanstastic movie! The dynamic range is incredible, and it reminded me a lot of Oblivion. I was hoping for a lot more extension, I feel as though it was probably filtered for the theater, but hopefully the Blu Ray is not.

How do we know that there is a high pass vs the movie just not having super low bass?

When I saw this in my local AMC I was disappointed at he bass. It all seemed to be 40hz and up.

If a movie does not contain ULF and they use real sounds it is HP! They exist in the real world and real world sounds will have them. You can look at the slopes of the drop off as well where some clearly show 2nd and 3rd order HP's. The syuff that is just low will have some ULF mixed in there with levels varying. The movies that just keep dropping are HP. Of course this is my observation and I could be totally wrong until someone whop really knows pops in.

humor me, does/would the graph look the same in whatever (lossy) english 5.1 track they included?

It's not just 7.1. There's many 5.1 BD's where the bass for the DD5.1 track has more punch than the lossless plus being louder. Twister is one of them.

The lossy track will still be better.

I just tried this after reading your post and what a surprise. I pulled out my SPL meter and the dub tracks sub output are around 10db louder. I also heard what was, to me, better details from the overall sound than the DTSMA track. The mid and high frequencies sounded more up front and in your face and clear. Lossless is suppose to be an uncompressed studio master mix is it not? Or is lossless audio suppose to balance things out or something? I don't get.

saprano I think what we are seeing isn't so much a lossy vs lossless debate but one that boils down to a 'near field' mix vs a theatrical mix debate. Unfortunately the near field mix is considered an 'upgrade' by the studios it seems - and if you are lucky they maybe will include the theatrical as a lossy aside. I mean why would you want some really big bass being played through your crappy home system? why would you want to use dolby volume or dynamic volume when the bluray can just mix it right into their lossless format and compress the dynamic range for you?
post #10968 of 16134
Oh Boy.

I really hope 'near field' is not equivalent to 'HTIB', or as I used to call them, 'kids table' mixes.

That could cause some real problems for our hearing if the nearfield mixes are louder when played at 'Reference'. I remember FilmMixer saying the SPL targets are different for nearfield mixes, which could result in differing playback levels if our receivers are set to playback at 'theater' reference.

From the pics I have seen of 'nearfield' mix rooms on the web, they are not very high output systems. No way some of these people are monitoring 105dB clean peaks out of MTMs with dome tweeters....

Was just reading that Pacific Rim has two DTS-MA tracks, one in 5.1 and one in 7.1. Does anyone have any idea at this point if there are any significant differences between the two mixes?

I'll let you know next week when it arrives, as I'm still hoping it turns to be another Oblivion where some of the early graphs almost had me in tears but remember how that one turned out wink.gif

Filtered tracks can sound good sometimes depending on how it was mixed. Thor was OK, Transformers 3 was pretty darn good for a filtered track. But lately all the filtered tracks are sucking even more and more. Those are the only filtered tracks that sounded good to me.

I actually just watched Transformers 3 last night again and agree with you. Besides extension not being what it could, the bass/LFE otherwise is fantastic IMO. The audio overall is one of my personal favorites on blu. The entire end section is jaw dropping audio work to my ears! I also liked Thor. Some tracks the filter is more obviously detrimental vs others. Hobbit is still the champ here followed by Avengers IMO.

Audiofan,

Thanks, but I am hoping to see some objective measurements between the 5.1 and 7.1 before watching my copy on Tues in case one does by chance have a better extending track. I am still planning a blind buy at this point.
post #10976 of 16134
I'll be watching Pacific Rim this weekend!
Can't wait and really hope the bass is insane!
Will post my thoughts when done

PS. I did a scene for a teaser to see how it sounded and went from 5.1 to 7.1 and saw very little difference.
I'm not sure what I thought about the bass...it did not seem that strong!
I will only comment AFTER I see it in full.

also I have a very capable system that's flat to 6HZ. Here's my graph!

Yep, it is one of the better tracks out there and one of my favourite filtered tracks lol....would of been better unfiltered but I was happy with the bass content in that movie.........compared to the crappy bass tracks were are getting these days eg The Hobbit/Avengers/IM3 etc

Cool, will look forward to hearing your thoughts. If it is filtered, so be it...nothing we can do........but for love of god hopefully they do bass properly like in Transformers 3.

Got moved into the new place. Ran a couple demos with 9. Damn I forgot how that sucker hits. The subfloor in my new place gives a very nice tactile pulse. My fiancé was like damn! And put a big smile on her face wink.gif

yeah, I agree. Hellboy 2's nearfield mix was more exception than rule with how they let the bass portions in imo.

Any graph on White House Down yet? Sorry if I miss it. Thanks.
