Thanks Dave...I also e-mailed you. Here is the graph:




EDIT: Dave, there is an update available for SL ...should I DL it?



Got it, and bingo:

One thing: Change the sampling rate back to 48k Hz. 96k Hz with a decimation of 4 (my setting) gives a sampling rate of 24,000 Hz. What that does is spread the resolution across twice the number of frequencies, which is why the graph is pixelated, like my old settings were (which is when I graphed the scene in the above pic for comparison).

If you change back to 48k Hz, it should match mine perfectly.

The only other thing is that with a 0-480 Hz scale, there are no division lines to tell you what frequency the content is. It would be perfect if there were an option for the grid in the waterfall to be in 30 Hz increments, but there is no such option, so for now, you have it as good as it can be.

It's just a glitch thing (the frequency scale) that I don't know how to deal with yet.

If you could change the sample rate to 48000 and run that scene 1 more thime, I'll appreciate it.

Thanks Dave!

Here is the graph with 48K Hz...now the division lines are back.

I also took the 0-120Hz scale from the other screen capture and pasted it on top of the 0-480Hz...do you think this will work?

P/A chart is off but I could do the same for it or skip it for individual scenes.

OK folks,

I got my correction file to get accurate data down to 2Hz to work. Here's Immortals (see previous post):

I will get to work on a few others today. Battle:LA is next.

EDIT - Updated, level-matched graph on previous post.

Battle:LA.

EDIT - Rankings below as well as updated graph.

Level - 4 Stars (112.11dB composite)
Extension - 5 Stars (1Hz)
Dynamics - 4 Stars (25.91dB)
Execution - 5 Stars - In my opinion, one of the finest mixes utilizing ULF ever created. No easily detectable clipping, utilization of the entire LFE band, and most of all, it sounded right. The helo ride to the FOB is great stuff. The alien weapons have a touch of 20 and below Hz to give them extra weight.

Overall rating - 4.5 Stars

Recommendation - Buy. This film has some cheesy parts, and I may be biased being a former US Marine, but I really think this is demo material.


The Incredible Hulk is next.

The Incredible Hulk. Still the one track I hold others to.

EDIT - Updated graph and Ratings below:

Level - 5 Stars (112.99dB composite)
Extension - 5 Stars (2Hz)
Dynamics - 4 Stars (25.61dB)
Execution - 5 Stars - Still the track I hold all others to. It has everything.

Overall Rating: 4.75 Stars

Avengers, the biggest LF disappointment of all time, but also indirectly the reason this thread was started, so you have to give it that.

Level - 4 Stars (110.53dB composite)
Extension - 2 Stars (21Hz)
Dynamics - 4 Stars (26.13dB)
Execution - 3 Stars - 1 Star deducted for lack of extension, 1 star deducted for lack of continuity with previous Marvel films, and a general 'mail-in' of the soundtrack. It is my personal theory that the highpass filter was put into effect after several subwoofer drivers were blown during the mixing of this film. It is too bad this got such filtering, as it is such a great film. You can even see sweeps that should have dug down to the teens just disappear in the filter's grasp. Oh well.

Overall Rating - 3.25 Stars. What a shame.

Overall Recommendation - Reluctantly, I still say BUY. It is that good a film, putting together all of the characters in a great way, with comic-book one-liners throughout.

Here's Tron:Legacy.

Level - 5 Stars (113.03dB composite)
Extension - 5-Stars (1Hz)
Dynamics - 4 Stars (25.26dB)
Execution - 3 Stars - Really good track, but look closely at the extension. Save for a few scenes, the average graph tells most of the tale. It's F10 is only 22Hz. The problem with this track is the clipping in the LCR and Surround channels (the LFE channel is suprisingly unaffected). An article reported that the director Joseph Kosinski went back and 'modified' the soundtrack for the BluRay release. Too bad. At first, I thought the clipping almost intentional, given Daft Punk's music style, but it is not always the case. 3 Stars for the clipping.

Overall Rating: 4.25 Stars

Recommendation - A reluctant Buy. The visuals in this film are so tremendous, that they can even overpower the botched sound at times.

I asked Kyle but he hasn't gotten back to me on this. I am stuck with the same problem myself. I will contact him again.

You know what's even more disappointing?? After I finished building my theater I was going to open with that pos. I haven't even seen it yet so it was going to a great opener and now...........it's a rental. You're right though at least something came from it.

Thanks for the graphs Max.

Your welcome folks.

I just figured out how to do real comparos with the films. Check it out, Battle:LA vs Avengers (had to downsize, ran out of upload space):

Any film can now be directly compared to another if a question should arise, and not just with the octave values.

JSS

PS - From all comparisons I have done, Immortals is King. Too bad the limiters clipped the track.

EDIT - Immortals is no longer king after a level-matching issue. Graph deleted to save upload space.

There are still many films to go, WOTW, WOTT, and others. So far, I threw in the heavy hitters I own or have on loan, and Immortals took it to 'em. I am again out of town this weekend. If I get a chance, I'll get some more graphs done after that, and update the first post with ratings and ask for consensus on them, as well as any other films to graph. I plan on doing Project X, Scott Pilgrim, CitW, Prometheus, The Transformers Films, and The Iron Man films as well as Captain America and other requests. We should have a really good databass soon.

Awesome stuff Max. Is there an export function out of SL? Never knew that if so...Looks like you are importing this into Excel or OO? Anyway really cool. Make sure that you do the movie 9 if you get a chance. I don't think it will best some of the super heavyweights but i expect it will earn it's 5 stars. Another good one would be The Hurt Locker.

BTW I brought the attachments limit to Kyle's attention last night. He is going to look into it when he gets a chance (He is closing on a new home so you know how that is. Might take a few days.) Sorry about that. We will get it fixed.

Ricci,

I export peak/avg screen caps from SpecLab, then extract the data using the Java application DataThief, then import that into Excel, to be able to generate all kinds of charts, and direct comparisons. I measured my roll off and applied a correction curve in Excel, so I am flat to 2Hz.

Dynamics per octave and overall can also be calculated by subtracting average from peak power calculations. These numbers combined with individual scene waterfalls should provide a solid objective reference for rating LF content in films.

I'll add 9 and The Hurt Locker as well as WotW to the Netflix queue.

Fantastic graph, Max! Comparisons like that would be very helpful. :)

One oldie from my dvd graphing days I'd like to see is Running Scared. Had some good single digit content, iirc. The openning shootout alone, even...

So I went back and was looking at some data....and found a mistake. Immortals is a bit high in level due to the settings I was using. I will re-run it when I get a chance....something tells me that TIH may end up on top again...

Finding the best way to do this to be able to do comparos has meant some trial and error...

I also found an error on Avengers and Tron. They were a dB or 2 too low, so they will be updated. I now have a checklist to follow to ensure all films will be level matched.

I also have Sin City to run in addition to all of the requests above...not expecting too much ULF, but I remember it being better than OK, and a terrific film...

OK, I got all of the graphs above level-matched and updated. More soon. Now that the graphs are level matched, here's TIH vs Immortals. Will update the first post with films graphed and rating soon.

Cool. Looks like TIH has one scene where there is a good 8.5Hz spike, but Immortals actually has more content below 25Hz overall?

BTW, I was curious about the B:LA trace. It looks like there is more content at 3Hz than anything else? Is that right? It's an odd looking trace compared to all the others.
