Frequency waterfall charts of a few familiar favourites - Page 2

post #31 of 531
You know Jeremy, I ended up goin there just last night and DOh! I found them...did not know they were there since I thought those were only older movies they had put together, Dark City, 5th Element..ect...hopefully they or someone do more as new movies are reviewed. I'd like to see where my SVS 22-31cs stacks up...

Hey guys, how do you know if a sub is producing harmonics or true signal (HZ)?
post #32 of 531
the only way to really know is to measure it.
post #33 of 531
I'm surprised nobody mentioned "The Haunting"...well besides having Catherine Zeta Jones as eye candy, its not a very good show, but its bass levels are up there with the best I think.
post #34 of 531
Sihan,

The Haunting is another one that SVS has on their site. (See link in post #25 above.)

Ming,

Just to clarify, I would be happy to see your software's version of any of these that have been mentioned that are already posted on SVS (U-571, Toy Story 2, Haunting, etc). The last one that SVS did was Phantom Menace and there have been several bass-heavy DVDs that have come out since TPM that I and others have been interested to see. Personally, I prefer Ming's flat waterfalls over SVS's 3D ones. Also, SVS's tend to be around 10-20 seconds at a time while Ming's have been a minute or more.

The next one that I'm waiting to see is Monsters, Inc. The "23-19" sock explosion, the "Hey Ted, Good Morning!" scene when the Godzilla/dinosaur monster steps off the curb, and two different instances when Boo laughs and knocks out the lights. Whenever you get around to it, Ming! Thanks!

Will be getting to TS2, Monsters Inc. But I'd really don't want to duplicate what SVS has. But just for you, I'll do it once I've run out of movies to plot. I do hope to be HTF's resident waterfall plotter, so I'll do my best to include everyone's suggestion; so once in a while, I'll post the few favourites, duplicated or not.

I don't have "The Haunting" so I'm not able to do a plot for that.



Just a few days ago, I tried plotting for "Panic Room" since I remembered hearing pretty deep bass (~20hz) in one of the high-tension moments. I can't find that scene now.

But definately, there is losta pretty deep bass scattered all over the movie. Go listen for it if the sub can go infrasonic.

Ok, will get to TS2 and M Inc friday nite! Happy listening.

Hi MingL:

The scene you are trying to find is when the leaking natural gas explodes and rips out of the ductwork and into the bedroom and panic room. Very impressive bass in that passage.

BTW, great work on this stuff. It's probably more time consuming that any of us realize and I'm sure I speak for all the readers when I say it is much appreciated.

It's really amazing how much high amplitude subsonic bass content exists in some of these DVDs. Full bore stuff at 10-12 Hz - holy moses!

Regards,

Ed

Monster Inc: 23-19 sock scene



Infrasonics down to 5hz? Yes. This sock scene appears to be impressive, but not all will feel the same.

There is alot of energy between 28hz to 45hz. This coincides with 35hz to 60hz room modes of typical HT setups. Therefore, whatever bass between 5hz and 20hz will most likely be unheard/unfelt as compared to the bulk at 30hz. Still an impressive scene.

Because there is still lots of infrasonic bass 10dBs lower than the peak at 30hz, the infrasonics can cause ported subs to unload and bottom-out.

That's why I moved up to dual Ultras. I can now get over 100 dB @ 10hz. Yowza! I could consistently bottom my single out with We Were Soldiers - "Broken Arrow" scene. If you've got that one, check it out!! I'd love to see how it measures. It could happen a number of times from when the jet launches from the carrier to when the dive bombers start dropping the bombs on the battlefield. I think it's my favorite and most awesome bass demo scene. Great movie too!! Incredible sound track!! Incredible story. Amazing thing is that it is a true story, very accurately and realistically produced. Not for the faint of heart.

I never tried Monsters Inc. at reference levels 'cause a different audience is involved for that flic here

Thanks again for all this, Ming!! It is very cool to SEE what I'm hearing!!

Ming,

What's next?

I'd still like to see your graphs of several other spots from Fellowship of the Ring:

-There's one sequence where Gandalf is looking at Mordor from a distance and then when the ringwraiths exit Minas Morgul and ride past our POV, there should be some deep bass there.
-When the four Hobbits are hiding under the roots of the tree and the wraith is scaring the bugs out of the ground, there are some deep synth. tones that would be cool to see.
-Cave troll
-Balrog

-Arizona explosion from Pearl Harbor

-You don't happen to be a Harry Connick, Jr. fan do you? On his 1994 album, She, there's a song, "Joe Slam And The Spaceship" that has some infrasonics worth looking at.

-Blue Man Group - "Audio" if you have it, I can identify some deep bass moments for you to chart.

Ming, it appears that I've got your work cut out for you! Thanks for your efforts.

Isn't it great to have a sub that can handle this material?

I know I'm loving it
post #41 of 531
hell ya mark!!! My bose system is kicking arse with this material!!!!!!
post #42 of 531
My Kenwood HTB Sub used to slope off pretty quick starting around 30-35Hz. It's amazing to see how much content there is in the depths that I was missing before I built my Tempest-based sonosub.

Like on Jurassic Lunch, pretty much all of the stomping content is below 30Hz, so I wasn't really hearing anything until the dino roars. Imagine my surprise when I listened to that track with the Tempest.

Just a show of hands, who wold like to see the bass content of Telarc's 1812 Overture hybrid SACD (CD layer) with the real-life cannons blasting off?
post #44 of 531
ok to 1812.


Ming, if you have Unbreakable there is this great infrasonic bass content at the beginning before the actual train derail.
It starts when Bruce Willis resting his head against the window.I don't think this scene was ever measured or published,it would be great to see it.

BTW use the DTS track on this one,this particular scene is much more "pronounced" on the DTS track then on the DD track.
Or for fun you can measure both.
Thanks!

Lewis,

"Unbreakable" is another that SVS has charted on their website. See "Train Ride" here.

MingL,

For what it's worth. SVS also has the Telarc 1812 cannon shots charted here, but again, I prefer your charts to theirs, so go for it!

I agree....I like your charts better

Yeah but I wonder if it's the DTS track, it is quiet louder,and I'm not talk about overall loudness,it seems that only the bass got pumped,at least on this scene.

Okie guys, here's a bass overload of the few "reference" dvds for bass.

Toy Story 2, opening Sequence




Generally a well loved bass test sequence. Bulk of the the loudest bass peaks are in the 30hz region, in the TS2 logo stomping onto screen and the rocket bursts from Buzz's rockets.

Infrasonics stretch really low here. Thou it does stretch almost to oHz, those are almost 20dBs lower than the 30hz peaks. But there are certain instances where the infrasonic bass can be felt without the overwhelming 30hz peak.

IMO, a bass fest for anyone without an EQ subwoofer system. Its practically bass everywhere from 0-100hz.

For those with subwoofer EQ'ed system, this disc will demonstrate what deep bass is all about: Controlled yet aggressive!

U-571 CH 15: Depth Charged

This is the initial portion of the U-571 "Depth Charged" chapter.



Here we start off with the german destroyer charging thru the water. That evident with that slight bass shot as indicated above.



Subsequently, depth charge explosions all peak about 30-40hz. It will be tough to pick out the infrasonics because we are constantly overwhelmed by the boomy explosions at those peak frequencies.

Generally, all the depth charge explosions are centred about 35hz, extending down below 15hz. Generally, all subs will do the explosions with aplomb. Not all subs will reach down deep thou. Is that gonna make a big diff whether it goes deep or not?

Frankly, its noticeable ONLY IF you've heard this movie with all its infrasonic glory intact. For someone who has never heard the movies with its infrasonics glory, it difficult for them to understand whats the big deal with the extra bass extension. For example, the infrasonics can only be felt/heard if the depth charges are explosion in the background. Esp in Chapter 15 (01:19:00-01:19:30) partially not captured in the waterfall charts where we have some smaller background explosions during a tense conversation. Those background explosions explode from 30hz to just below 20hz. We can easily point out these have some infrasonics since its not overwhelmd by 40hz bass peaks unlike normal close-quarter explosions. Close quarter explosions will overwhelm all infrasonics with all its low-mid bass content.

On a bass head POV, the depth charges will impress visitors not familiar with deep bass. It goes loud, heavy and scary. Palms sweating, legs shivering and eye lid flapping bass.

Definately a good movie to show off any subwoofer. Not a movie to show off infrasonic ability, but good enough to show off bass quantity.

IMO, this movie will clearly be one of the best movies to show off and demo the benefits of with and without subwoofin' EQ. With room modes typically between 30-50hz, a good EQ standard will remove the blurred and smeared bass details which otherwise un-eq'ed system will suffer from. Try it! It certainly was the case with my BFD on/off comparison!

Just remember we'll need a house curve to show it all off!

I'll just do a quick one for Telarc's SACD hybrid 1812 Overture later on.

Have been slightly busier lately coz I'm starting to learn the ropes of THD testing for my SVS.

I'll come back more with fight club, and boo crying/laughing scenes from Monster Inc.

As always GREAT job MingL!
post #53 of 531
Hey Ming,

I know this will sound funny here with the likes of Jurassic Lunch, FOTR, SWII, etc. but do you happen to have "Notting Hill" in your collection?

My wife and I were watching this last night for the first time since I built my Tempest sonosub. During Chapter 3 when Anna kisses William, there's a pretty nice rumble that I had never noticed before. I'm guessing that it's in the 24-26Hz range with decent amplitude. There are also a few other similar effects other times in the film (like when Anna first comes into William's bookstore) but those are more like 50Hz I'd guess.

I did a search here and read a few of the DVD reviews on other sites and didn't see any mention of this. Some of the reviews complain that this is your "typical romantic comedy soundtrack" - front heavy, no surrounds, no LFE . . . and generally this is true. But this one scene is probably deep enough that some miss it entirely. Anybody else (who's willing to admit having it :b or renting it) ever noticed this? Just curious.

Yes, Jeremy, you're indeed right. I'm not able to post a waterfall chart for this but here's what I measured.

A deep rumbly at ~22hz along with a second rumble at about 45hz, about 10dBs lower. It lasts as long as the duration of the kiss. I guess its suppose to warm the audience's heart during that kiss.

Most normal subs wouldn't even bring this bass detail loud enough to hear, so I suppose only the priviledged few will be lucky to discover this treat!

Oh, and more movies are using this deep bass to enhance the mood of the film. "Children of the corn" has one such scene where the heartbeat actually pulsates at 20hz.

Thanks, MingL! I never expected such a quick response.

Movie: 8 mile

The last battle scene (approx the last 20 or so minutes of the movie) has a couple of instances where the announcer's mic gets turned off/on or unplugged or something similar... This results in one of the lowest frequency shockwaves I've ever felt through my Paradigm Servo-15.

We've all heard the sound: You've got an amp turned up and you pull a mic out of the plug.

Anyone else notice this? I think it's probably a complete mistake that it was included, but it's frequency is so low it's not at all heard, just felt - most subs wouldn't even play it properly. I rewound the movie and bit I watched the excursion on the Server-15 driver on this - quite scary!

Any new ones Mingl? I just got a pair of new subs and I'm on the lookout for the super low stuff that ALL of my friends are missing in there HT set up.

Great work Ming. Hopefully this won't lead to a bunch of blown woofers. Four or five years ago when the Telarc CD first came out I played the "Jurassic Lunch" cut on an 18" Velodyne servo sub and at first heard nothing, then in a few seconds I heard some cracking sounds coming from a bedroom followed by severe rattling in a china closet in the nearby kitchen. It was unreal and I repeated it several times for audio friends. One even insisted on hearing it on his Bag End 18". On the Bag End we saw a lot of cone activity but not much else. I also tried a JBL B-460 (18 in a ported enclosure), but it didn't even respond. The CD has a disclaimer regarding the deep bass and I would advise all to be very careful about the level you try to play it at, especially with small or ported subs. Ported subs do not offer the mechanical protection that a sealed box does so play with care. These tracks add some validity to owning multiple 18's.

I'm looking forward to the next wave of blockbuster movies. Have got myself a preview copy of the LOTR:TTT DVD that will impress most deep bass freaks. Hint: Blackriders on wings Sorry, this scene is not available on current DVDs as any trailers.

I'll check out 8 mile soon(not today).
