In audacity when you export as a wave it will combine all the tracks to mono

That worked!
But, are the levels correct after this or should I adjust using a level offset?

Lookin good! Curious about the levels too. Since what we hear is the sum total of the levels, I'd THINK this was more accurate, but we know what they say about assuming. Although the per channel standard maximums for THX Reference are 105db for the satellites and 115db, the sum total of all the channels playing on a soundtrack can hit 122+db.

So, hmmm, does that mean I should introduce a 7db offset then to reflect the proper 0dB?

You can't tell anything about SPL levels from those charts. The dB levels do not represent dB FS levels. They are relative dB levels that are shown for a small part of the signal bandwidth.

If you do a careful calibration of a single input channel, you can calibrate to dB FS.

For single channel inputs the graphs are calibrated. (Using a -20db 50hz signal).
How do I calibrate when using (a combined) multi channel input?

You shouldn't need an offset. the +10db on the LFE is done by the receiver. So a 0db signal on a main channel is 105db if your receiver is calibrated and MV is 0db, if a 0db signal is sent to your LFE channel its 115db if calibrated.

However, weather it should be calibrated or not I am not sure. But once they are all combined 0db should be 0db on all channels vs just one. What that 0db is compared to just the LFE is different but as long as that is understood before looking at the chart it shouldn't matter.

Speaking of LFE....My denon has an LFE and an LFE+Main setting...What is the difference between the two?

To keep it both simple and accurate, I did a full cut-n-paste from our Marantz, SR5007 user manual; pg 124. The information should translate over to your Denon model.

Manual Setup Default settings are underlined.
Perform when setting the speakers manually or when changing settings made in Audyssey® Setup.
• If you change the speaker settings after performing Audyssey® Setup, it will not be possible to select
Audyssey MultEQ® XT, Audyssey Dynamic EQ® and Audyssey Dynamic Volume® (vpage 109).
• “Manual Setup” can be used without changing the settings. Please set if necessary.

Yes and it has got a very very good soundtrack. The picture quality is just as immaculate.
I could give the movie at least 4.5 for bass. If not that high it would be because the really bassy scenes are brief? They aren't throughout the movie. I'm assuming you have watched the movie, the times when the alien mother ship starts up, my whole room quaked. smile.gif
It's got a 5 star for audio on the bluray.com review of it as well, so check it out!

I should have bought it when I saw it at Best buy for $9.99. I actually am one of the few people I know thta really enjoyed the movie. I could imagine some of the scenes are crazy bass like you mentioned.

Hmmm... that depends. If the absolute ceiling for the graph is 0db, then I would use -10db, as it is possible for the sum total of 5 channels at THX Reference to exceed 122db for brief spikes. -10db would accommodate 125db summed totals.

As long as folks understand that, it's good. What actually matters most is the relative levels between consistently taken graphs. If one of your new summed total graphs ever hits 0db on the graph, it's gonna be loud. I'd love to see the comparison between the new and old WOTW graphs.

Hey, have you guys checked out The Raid: Redemption? I'm sorry that I can't contribute measurements, but what I heard through my beer budget system made me feel like it's pretty generous with the low tones. It's also a stunning action movie.
post #6105 of 16129
Is Brave really filtered? confused.gif I just watched this and listened to the TrueHD 7.1 track and it did not sound/feel filtered at all to me, but obviously my perceptions could be off. I had the hair moving, room shaking, etc....like I get with other unfiltered tracks and the LFE in general I thought was VERY well done. I think some of the more recent Pixar offerings have had somewhat conservative LFE use compared to the films like Nemo, Incredibles, Monsters Inc and Brave felt like it was back up to par with the best Pixar films from a low end perspective. Not going to give the big boys a run for their money or anything, but still subjectively I found this to be a great LFE track and it supported the film perfectly.

I know the French track was graphed and shown to be filtered, but have we checked the TrueHD 7.1 English track yet? If this track is filtered, this has to be among the better filtered LFE tracks out there! tongue.gif Most filtered tracks I can tell something is missing like Avengers for example........it was noticeable. I just did not get that feeling with Brave and if it is filtered, it fooled me.

The Raid: Redemption.

Definitely some stuff under 20 but not a whole lot.

I dont have a receiver in the signal path.
Also, I believe it is important that everyones graphs are made in a similar way so they can be compared to each other. A db here or there doesnt really matter much, but the 5-15db we are talking about here is way to much in my opinion.

Since Im going to need to adjust the offset I should do it correctly. I just need to figure out the correct value.

I can post updated WOTW graphs. Gimme a bit of time.

WOTW LFE

WOTW all channels combined. NO OFFSET!

Just looking at the LFE track in Audacity you can tell that its a bass monster....

The dark knight rises. DTS-HD Master Audio 5.1

f9172012441033481.jpg


Absolute >20hz monster. Its looking awesome! Going to do a few individual scenes of this one. Finally something worth the attention! Slight roll off below 20hz though so not an ULF monster. Guessing 4.5-5 star rating for this one.
Please note that this graph might be missing a level offset. Please compare to WOTW above for reference.

Why not see for yourself?

Just watched the new Spiderman. Might be the first movie I've heard with filtering above 20hz. Strange track. Seems to almost be missing some frequencies.

Here's one that may have flown under everyones radar, have not seen it listed anywhere

 

I caught it on MovieCentral HD purely by accident this afternoon,

Holy Crap my Big 15" Velodyne was Very active with intense very low LFE throughout the whole movie!

 

http://bluray.highdefdigest.com/6044/afraid_dark.html

 

I may have to get the DTS-HD Bluray now.

True. Me and The Bland were talking about this in another thread. While I enjoyed the SM LFE, it did seem a bit lacking in the mid bass which hurt the overall score IMO since the bass was missing that full bodied sound in a fair amount of the track. I would go about 4 overall.

Spider-man kicked my ass! not WOTW hot, but still really deep

it definitely was missing content above 30Hz, weird mix for sure

 

Ran my Yamaha RX-V3900 at 0, sub level at +3 hot

quick screen shot on my 50" plasma, chapter 16, time stamp 2:07:24 to 2:07:28 is a slow-mo helocopter type thumping thats ULF

(near feild 15" Velodyne right behind my center seat sweet spot)

Something definitely felt off about The Amazing Spider-Man's bass. Was it purposely crippled? For a superhero movie the soundtrack did not wow me in the least.

I noticed when things were shaking and rattling in the house (inaudibly), yet I couldn't hear much LFE, that something was up. Probably the first track that I've heard (or not heard) like this. Many times you'd feel the low music more than almost any action scene. If I were to critique it on a technical level, in fact, I'd say it was almost a "bad" audio track, but for a completely different reason than most people usually judge LFE tracks.
