Max are those SPL levels representative? 140dB?

 

No, they are power levels per octave, in dBHz. I calculate the 'area under the curve' for each octave. I think more people would like dBHz than PaHz, so I am going with dBHz for graphing. All area calculations are done in PaHz, and converted to dBHz for graphing. Basically, if you were to add the sound pressure of each 1Hz bin for an entire octave, and add them all together, then convert to dB, you'd get the numbers shown above. Since the upper bass octaves comprise more 1Hz bins, the numbers are generally higher as you go up each octave.

Just a thought I am throwing out here, is to start another thread were all could discuss the execution or the buy/rent upon seeing the graphs and data here. As this is somewhat subjective and could keep this thread for the data goods.

 

If this thread becomes too bogged down with subjective argument, a new thread would be perfect. Since I will be indexing on the first page (as I get time), it should be OK for now.

Great job guys, I've been following along.

 

I've always been interested in spectral weight, especially the relative spectral weight of certain scenes to be used for system evaluation and proper gain structure.

 

So thanks to all involved.

This Spidey edition was fun. The low end was not a top tier level (for me, we shall see when Max puts up the graphs and ratings, which I will update the post with), but since there was no single credited Sound Designer, I had to dig deeper and found Distortion Music & Sound did the sound design for this and many other great MWB, which is the good that came from graphing it.

 

The low end is good and where it needs to be. It's not filtered, with shotgun blasts and wind effects going all the way down.

 

Max, AWESOME: Star Trek. I have tons of graphs for this one, but they lack the top and side graphs. Dunno if I'll do them over or use what I have, given the amount of time req'd to do each movie. Either way, it's on it's way, so look for it this week.

 

BTW... I slowed the scroll speed for the Spidey/Lizard Dude fight scene to get more of it in the graph rather than do 3 or more graphs, in case anyone is wondering why it looks different.

 

I'll do that from time to time rather than cut a great scene off partially done, so if you see the squeezed effect, you'll know why it's so.

Here's Batman Begins:

Level - 3 Stars (108.47dB composite)
Extension - 5 Stars (1Hz)
Dynamics - 5 Stars (27.51dB)
Execution - 4 Stars - While the LF was well done, I can think of many better, hence the 4-Stars.

Overall - 4.25 Stars

Recommendation - Rent, if you are fan of Nolan's Batman, Buy.

Iron Man:

Level - 4 Stars (112.2dB composite)
Extension - 3 Stars (16Hz on Avg Graph)
Dynamics - 4 Stars (27.06dB) .
Execution - 4 Stars - Could have used some subterranean effects, this is a 30Hz movie with a little juice below. But overall nice track.

Overall - 3.75 Stars

Recommendation - Buy. This used to be one and still is one of the most well-regarded LF tracks out there, and a terrific film.

Iron Man 2:

Level - 4 Stars (111.94dB composite)
Extension - 4 Stars (14Hz)
Dynamics - 4 Stars (26.33dB)
Execution - 4 Stars - Again, 30Hz rolloff in use, like many films. Lack of high level stuff below ~25Hz, too bad. Good film, terrific soundtrack otherwise. Another 'might have been'.

Overall Rating - 4 Stars

Recommendation - Buy. It is a good sequel to Iron Man, and although essentially a 30Hz film, I think it is worth it.

The Dark Knight:

 

Level - 2 Stars (262.03dBHz) This is not a mistake.

Extension - 5 Stars (2 Hz)

Dynamics - 5 Stars (29dB) Highest Yet!

Execution - 4 Stars - More 10-20Hz effects would have been nice. Great soundtrack overall.

 

Overall Rating - 4 Stars

 

Recommendation - Buy

 

As soon as Bosso updates the graphics for TDK with the above ratings, I'll index it to the first post and copy the images here.

It's updated.

Indexed and images linked! No data tonight, sorry guys. Gonna get crackin' on it prob tomorrow eve....

 

By this weekend, hopefully Assassin's Bullet, Amazing Spider Man, Cabin in the Woods, and 9, and hopefully some more of the oldies, and then will work on a 'how-to' for scene caps. As the databass grows, some trends are appearing.....

WOTW... check the new Title Block with rating system and tell me if it's OK or suggest a change...

Hey Dave, I was just checking out these graphs again and had a couple of questions:

In the graphs for Chapters 4 and 5, there is much more intense coloration in the graph below 20Hz for the Chp 4 graph than the Chp 5 graph, but the peak traces at the top of the graphs appear very similar for 4 & 5? Any idea why that is? Based on the colors, I would have expected Chp 4 to show much higher Peak (and Average) activity, especially below 10Hz (of course for ULF, Chp 9 is still King Of The Hill).

Good observation Max. They are very similar. I would expect them to be the same up until 20hz where Chap 4 should have a very noticeable increase. Also the average graph in Chap 4 is steady across the entire BW and then at 20hz drops off where it seems it should start to raise??

 

I also was looking at the TDK graphs and while it goes down to 2hz it doesn't do it that often and in the other graphs it barely goes below 20hz. I was just thinking it maybe should only be a 4 star in extension. Yes it goes down low, but not very often and most of it is centered around 40-50hz. When you compare it to WotW in extension I just don't think they should both be 5 stars. WotW has several scenes where the bass is centered below. I realize the criteria is whether or not it contains bass down low, but when it is just a few times and just a spot or two of bass I don't think it should be 5 star. Idk. What do you think MaxM and Dave??

Yes, sometimes the peak hold has not reset from the last graph. For each cap I have to grab the graph, send it to paint and crop/name it, snap a pic of and note the time stamp of the beginning and end of the scene.

 

Sitting there waiting for the PH to reset is a drag, especially when you have a dozen movies to catch up on and losing the PH because you set it shorter but took too long to set the screen to a decent frame to take a pic of it just as aggravating, especially when all you have to do is glance at the colors and you have that information anyway.

 

I believe I'm going to eliminate the PH/Ave bar from my caps, as I have in the past. This will allow me to use the dozens I already have without having to do them all over for the sake of the PH/Ave feature.

I think that is a great idea, and would save a ton of redundant work. The waterfalls are awesome for relative levels per frequency in a scene and esp for specific effects (sweeps, booms), and don't necessarily need the P/A graph there as well.

X-Men tonight.
