Frequency waterfall charts of a few familiar favourites - Page 9

I don't have it. Maybe I can rent it some day...

FOTP hasn't been released here yet (R2). I'll rent those others some day, I don't buy those kind of movies (=crap).

Hi Ilkka,

What about that first scene in (SW II) we were talking about over at AVS? The "first" Fly-By of the chrome ship. I know it's been plotted before, but a little up-date in regards, might confirm our calculations. I can give you the :Time-stamp: if you like?

SW2:AOTC (R2 DD-EX)

Check above steve. It's a pretty steady 30-31Hz signal.

30 Hz.... Thanks Ilkka. I guess we'll stay at +3 for correction then. Nice job and very detailed.

Hi,
I’m going to try doing a few waterfall charts over the next week or two.
My first on here will be: Lord of the Rings: The Fellowship of the Ring EE.

I plan on doing the other two LOTR EE's and also I have started on:
Star Wars Ep. 1
Titan A.E
Chronicles of Riddick
Chesky's Magnificent, fabulous, absurd and insane musical 5.1 surround show.

The way I am getting the info and recording what you will see, is via the following steps:

1) I am using my spare Yamaha DVD-CX1 DVD player,
the Audio setting on it are as follows:
Speaker Setting: Multi-Channel (speaker levels set @ 0dB)
PCM Down Conversion: No
Dolby Digital: Bitstream
DTS Digital Surround: Bitstream
D. Range Compression - Off

2) I then connected a Tara Labs subwoofer cable to the
Multi Channel Output/Sub Out Jack on the back of the DVD player.
3) I then ran that cable to my PC.
I have a ‘Sound Blaster Audigy Platinum Ex’ Sound card.
4) I connected a Monster THX Y-Splitter cable to the end of the Tara Labs sub cable.
5) I then connected the cables to the ‘Aux 2’ Left and Right Inputs
on my Break-out box of the Sound Card.
6) I then set my PC to only listen to and record from the Aux 2 input.
Every other input source and audio component was muted.
7) I then used Speclab to analyse the audio info coming from the DVD
Players Sub out jack.

So, all I am analysing is the LFE channel, the .1 channel. I am not crossing over or getting any other info from any other speakers, this theoretically is ONLY the dedicated Sub info that you will be seeing.
If you have crossed over speakers and Bass management, then obviously you may have more info than what is shown here. But I just wanted to make that clear, this is only the Sub channel, there in no front, surround or center channel info being added here.

The setting in the Speclab program are all default. The only thing I changed are the following.
The frequency range if from 0Hz to 120Hz
The volume levels are from -70dB to 0dB
The waterfall scroll intervals are set to 200ms, relatively fast.
And the colours you can see from the chart Keys.

Let me know if there is something not properly done/setup here, should I change the way I am recording and getting my info? To me it seems ok, but I may have missed something.

Also, please let me know what you think so far of the charts themselves, and if I can improve the layout, make it any better, or if there is any more details you would like added?

Enjoy.

Cheers
KJ




The Lord of the Rings, the Fellowship of the Ring (LORT:FR), if some of you have never seen it before is the first instalment in a set of three movies.
I have the PAL version, Region 4, Extended Edition and I used the DTS:ES soundtrack.
LOTR:FR is relatively mild in its bass content, with most people and their sub being able to advantage of the movie and get impressive results.
The main part which I like the best is in Moria, with the Balrog. There is some nice lower level bass there.
Nevertheless, this is still an awesome movie, even if from a ‘bass content’ point of view, the three and a half hour movie is a bit lacking.

Dr. Chesky's Magnificent, Fabulous, Absurd & Insane Musical 5.1 Surround Show.

This is I DVD-A I came across on a shelf one day, I nearly didn't buy it. But after I saw the warning they have on the back of the DVD case :

"WARNING! This disc contains extremely low and powerful bass levels. Set you volume very low at first.
Chesky Records is not responsible for any damage to your speakers."

I though, maybe this could be good

So I bought it, put it my DVD player and played it (note this was before I got my new DD-18 sub).
Yeah, it was ok, certainly was weird and absurd and different. Yet it did grow on me after a while, for it's great use and show-off of surround sound and audio quality.
Anyway, jump a few months forward, after getting a new sub; I played the disc again
. . .
WOW, this has some seriously low bass in it, and is great for anyone wanting to see how much furniture your sub can move across a room, or to test for any broken windows (or at least they will be broken after you listen to the disk to loud)


This is a DVD-Audio, and anybody who is familiar with Chesky Records, knows that they are renowned for their audio quality in recordings. This disk is no exception.
However, I only made the waterfall charts off of the Dolby Digital track present on the Disk, because some people may not have the ability to play DVD-A. But if you do, the DVD-A tracks are of superior quality.

This disk has the weirdest collection of tracks you'll probably find. There is a basket ball game, subway train ride, thunderstorm, mice running around the room, heartbeats, and DRUMs, lots and lots of drums beats from weird and wonderful, exotic drums.
The tracks you’ll see below are the really deep bass content ones, but there are plenty more with a lot of bass between 30Hz and 80Hz.
So if you really want to take advantage of this DVD, you really do need a sub(s) that can reach down deep to at least 18Hz. The first track is a good example. If your sub rolls off at around 28Hz-30Hz, you are missing 90% of the track.

Anyways,

Enjoy


Cheers
KJ

Last chart for today

Titan A.E. (PAL, region 4 version)

This was a pleasantly, surprisingly, good movie. My younger brother borrowed it from the video store just for a new cartoon to watch.
When he had finished, he came down and said to me that it had some good sound effect.
Anyway, I went and watched it as well.

This movie, as most of you know, is a killer in LFE effects.
The opening sequence and the closing sequence are some of the most impressive I’ve seen/heard/felt, and I recommend that (if you have already) watch this movie just for those scenes.

There is a lot of LOUD info from around 15Hz and up in this movie. Pretty much every spaceship fly-by, gun shot and explosion in this movie is room shaking.

Again, just to note, this is ONLY the LFE channel.
If you have your main speakers crossed over at say, 60Hz, you will also get a lot more bass playing out of your sub.
This movie is a prime example why, even if your speakers can go flat to 30Hz, you still should crossover at maybe, 40Hz and send the rest of the bass to a capable Subwoofer.
Because the info from 30Hz down in the front channels will be lost if not crossed over. Because there is a lot of LOW info in the front Left and Right channels that ISN’T in the dedicated LFE channel.
And that is just speaking about those of you who do have large speakers that can go flat to 30Hz, most of us don't have speakers like that, so all the more reason to let the Sub do the work and get as much house crumbling bass as possible.

This movie is a must for those who like a little bit of good vibrations (not the Beach Boys) in your HT room. It's a great demo disc.

Enjoy

Cheers, and good night,
KJ

Fucking awesome, Kaj!

Kaj,

You are doing your thing, and doing it BIG too!

-Ming
-Rudi
-Ilkka

You guys are great for making this the best waterfall thread around! Keep up the great work.

Thanks for the comments
As i said, let me know if there is anything else you would like to see with these charts.

I plan to do LOTR Two Towers today, I'll see how i go

Also, it was asked if anybody was going to do Flight of the Pheonix, and just so your hope aren't up, i do not have a copy of the movie as it has not been released yet down in my part of the world, so i do it


And one quick thing, if you are interested, just to follow up on my point with crossing over speakers etc.
Here is a chart of part of the opeing sequence from Titan A.E. again (compare to above) but this time it is ONLY THE FRONT LEFT AND RIGHT CHANNEL INFO. there is NO sub data in this chart.
As you'll see, there is a fair amount of deep info here as well, and i am sure most people may be missing.
It is the same with most movies.
But of course, if you have huge speakers it dosn't matter much.
anyways . . . just if you were interested.

Cheers
KJ

Kaj, I was just about to ask you to do just this. LFE material without the LFE channel going. This is cool stuff to see.

I have a few requests. Off the top of my head: the Haunting, Saving Private Ryan, and maybe The Day After Tommorow. Specifically, the part when the Atlantic Ocean is bulding up and moving towards New York.

BTW- It would be easier to know when a specific moment happens if you highlight the area where you want are attention. Like the one MingL did for AotC and iRobot.

Kaj,
I second the Day After Tommorow,but a different scene.It's when the fuel lines are froze on a helicopter that was sent to rescue the British Royals. I don't own this disc so I can't give specific time and chapter info,hopefully someone else can. Thanks!

kaj, great stuff! the only movie to ever bottom out my 450-pound sub was The Grudge. if you can get your hands on that movie, it would be one of the best waterfalls available. specifically the knocking towards the end.

eric

Hi all again,

I just finished the Lord of the Rings: The Two Towers. (Region 4, PAL version)

And here it is.


Again note, this is only the dedicated LFE channel. There is a lot of deep info ALSO contained in the fronts and centre channel, so make sure you have you speakers setup correctly. A good example is when Treebeard is talking.
A lot of the 'filler in' bass or 'background' bass is contained in the speaker channels, so make sure you are not missing it.

Anyway,

If you haven't seen this movie (which I highly doubt ) this is a must see, there are a few scenes in here which I especially like, and recommend;

Where the wall is blown up at Helms Deep.
Whenever a Nazgul is onscreen.
When the Gate at Mordor is opened,
When the Horn at Helms Deep is blown,
and the Ents attack on Isengard.

Most of the bass in this movie is at around 30Hz and up, with a few goodies and 20Hz and below.


Anyway, now for the charts.
















Also, Scott Simonian said

"BTW- It would be easier to know when a specific moment happens if you highlight the area where you want are attention. Like the one MingL did for AotC and iRobot."

In reply; I’ll give it a go, See what i can do

My next on which i have already started, is chronicles of Riddick.

I'm not sure when i'll be able to get my hands on a copy of The Grudge, maybe over the enxt couple of weeks.

Well,

Enjoy again


Cheers
KJ

I will do The Haunting and Saving Private Ryan shortly (means around wednesday).

Hello again,

Here is Riddick.

This is was a suprisingly good movie, i quite enjoyed it.

There is a fair amount of LFE in here with a few nice parts, mainly the planet takeover. most of the deep stuff hits 15Hz, with a few parts hitting 10Hz.

I forgot to add the colour scale/key to these charts, so i ask you forgive me, it is just to much of a pain to go back though and add them.
So just to re-cap:

Yello = good
Red = even better
Dark Red = great stuff
and Pink = uber

my next one, hopefully will be Lord of the Rings: The Return of the King, and i'm looking forward it.











Also, if there are any parts/sections of any movie that i have done so far, that you would like to see a waterfall chart from another channel created i.e. Fronts, Center, Surrounds. Let me know.

and again, any suggestions on improvement, say so.

Enjoy

Cheers
KJ

This is a ton of effort, so let me first say thanks and that they are great. If you could expand the vertical scale for more detail, that would be helpful. I have a habit of looking for the pink colors and they are hard to see with the scale you have selected. Thanks.

hi,


I'll see what i can do with my next set of charts i'll play around with my colour settings and chart speed.

Though i might add, honestly, if you can't really tell any 'Pink' parts, then there aren't really any.
Because believe me, if there is a part that is that loud and of decent duration, you will know and see it clearly, and i'll be pointing it out anyway already

But yeah, i'll see if i can imporve it a bit more

thanks for the input

Cheers
KJ

(i might also note, the way i compress the pics, is quite good, and you can actually copy the pics and zoom in a fair amount while keeping a decent level of detail, but whether that helps or not. . . )

Kaj, you're spoiling us.

KEEP IT UP!!

I like the addition of the arrow from the screengrab to the waterfall chart showing where and when events are happening.

JKS

looks great, and highly appreciated.
Since you're asking for suggestions, I'm wondering if there's a way to weigh the scaling... seems like it goes from -70db to 0 linear, blue to pink... but the collective 'we' here are probably more interested in the -30db to 0 range... is there any way to shift it such that the color goes something along the lines of:
-70 to -41 = blue
-40 to -31 = green
-30 to -26 = darker green
-25 to -21 = yellow
-20 to -16 = orange
-15 to -11 = red
-10 to -6 = dark red
-5 to 0 = pink

which would lump the quieter stuff away and focus (and differentiate) on the good area?

how does this suit your fancy:

I used Toy Story 2, the opening part, as it is quick, easy and familiar.

I can have whatever colour you would like. If you don't like the Green, i can use shades of Blue instead, though i thought the green added a better contrast.

Let me know what you would prefer. Do these colours make things clearer, or did you prefer the previous style of charts?
The colours are FULLY editable, i can do what ever you like. I can also save the profile and send it to others if they would like to use the same colour scheme.
Or, if you have a scheme of your own that you'd like me to try out, then let me know and send it to me.

cheers
KJ




This next chart is the FRONT LEFT AND RIGHT Channels, it is suprising the deep bass present here. In fact, note the 00:01:15 point, and compare it to the LFE info. If you don't have your speakers crossed over, you will miss the best bit in that section that goes down to 10Hz. The really deep bass is in the Front channels, not the sub channel.

I'm going to have to email you what I have in mind, since I can't put pictures up it seems... (at least I don't know how)
maybe you can take one scene and do a comparison between the various color schemes to see which one provides us better resolution?
again, your work is greatly appreciated as is, so please don't take this as criticism.

Edit1: (I emailed you twice... the second email has the right picture...)

Edit2: if it's some kind of text file that specifies these ranges, feel free to email me that file... I'll see if I can doctor it up to look like what I have in mind.

Hello again,

Ok, here are three other colour schemes that may be used. (plus the above, previously posted, ones)
(BillyHC, I think the second one I made is what you had in mind???? I hope)

I am here to post the charts, so you tell me how you like them . . . you guys probably know more what you are looking for than I do

Let me know on these . . . again, I can change them at will.

(I am taking no offence or anything : D, in fact, I am surprised at the enthusiasm/response with these things, it's great )

Cheers
KJ

NOTE: the lines in the Colour Key range from -70dB to 0dB, in 10dB intervals.
There is rarely much info in the -10dB to 0dB section, as that is an extreme. Most info, useful info, is between -40dB and -10dB.
The speed has been changed to update the chart every 100ms, so it is a bit more streched on the vertical axis.
The frequency range of the chart has been limited now to only 100Hz.

Kaj, an excellent work much improved for easy viewing.
Now if you would only graph the Day After Tommorow scene I've been asking,[do you have that disc?] I'm dying to see that particular scene[chopper fuel line froze].
Thanks!

thanks, . . . so which chart did you like best? there are four different styles?


Sorry to dissapoint, but i do not have a copy of The Day After Tommorrow.
Believe me, i'd have done it already if i did.
I didn't think it was that great of a movie to purchase, so either somebody else will have to do it, or you'll need to wait till i get a chance to borrow it from the video store, or if sombody has a few spare copies, i'd be more than happy to recieve one, for testing purposes of course

anways,
sorry,

Cheers
KJ

well, funny how things work out

I just went out for a bit, and saw The Day After Tomorrow on special, so i thought, why not, and got it.

I'll have the charts up within the next few days hopefully

SO PLEASE, if you can, let me know how you want the charts displayed, so far i personally like the last one that i did, with the Blue background.
If i get no feedback, i'll go with that one. if you prefer another format, LET ME KNOW.

Cheers
KJ

And for those of you who would like a quick preview of what is to come, here is the requested helicopter freezing scene.

NICE!!! . . . you gotta love the bass present here, even though it is short.

anway . . .

LOTR Return of the King
and The Day After Tomorrow
hopefully both coming up over the next couple of weeks.
(I am not sure when i'll be able to get a hold of the Grudge, maybe someone else may do that one)

Cheers
KJ

again, i won't be able to start this movie for the next day or so, SO PLEASE let me know which chart format/colouring you want (one of the formats already posted, or a completely different one, i don't care)! But once i get started, it'll be too late
