i like adobe audition. works really well for situations like this. i'm sure there's another prog you can use, but that's my personal fav.

found this on another site

All .vob files have the video and audio multiplexed together, so they need to be separated out as a first step. You can do this with VOBEdit, which handles .mp2 and ac3 audio.

Once you have the audio file, if it's an .mp2 you can open it with Audacity and raise the volume (= increase the amplitude). If it's .ac3 then you will need a free trial of some commercial software like Womble MPEG Video Wizard to do this step.

Either way, you then need to remultiplex the changed audio back with the video file. You can use ImagoMPEG-Muxer to do this.

Then you should have your .vob file back with increased volume...

vob edit....nice.....thanx that is exactly what i was looking for...a program that runs direct from the exe....i have cool edit to do the audio...but.....

supposedly cool edit supports ac3...but im not getting anything but interference out of the ac3 file when i open it in cool edit...when checked with vlc player the file plays fine....funny

any help from here?
thanx so far
JR

::::edit....hahahaha....cool edit is now adobe audition

Posted by Mother on 11-09-2007 09:49 AM:

If the AC3 stream has the correct dialnorm value, there should be no need to alter volume. The decoder in your DVD player or AV recevier will read the dialnorm and normalize the sound to Dolby's reference level.

You can use VOBDNorm to directly alter the dialnorm value of AC3 tracks within VOBs - without the need to demux or re-encode. For example, if the original stream has a dialnorm of 27, changing it to 31 will give you a 4dB increase on playback.

hmmmm....you do know who you are talking to right?

anyways i gave it a pop....not only do i know what a cmd prompt is...i actually know how to open one...but thats about as far as my knowledge gets...

anyway i found this http://forum.videohelp.com/topic322240.html and the tail end is from the programmer for the app....but shn might do better explaining it to me cause i think its in french

can you give me the actual commands?

quote:
Code: "path-to-exe\vobdnorm.exe" "input.vob" "output.vob" 31

i take that to mean at the prompt type

"G:\DL Shit\vobdnorm\vobdnorm.exe" "VTS_01_1.VOB" "VTS_01_1fix.VOB" 31

but the input file is not found...i put it in the same folder as the vobdnorm.exe...
also supposedly i can add the other file i want to raise it to and it will seek its own volumes...any clue on how to do that?

Posted by Jay Are on 11-10-2007 08:25 AM:

typically with a command prompt situation, you would have to put the path again when telling it which .vob is the source.

"G:\DL Shit\vobdnorm\vobdnorm.exe" "g:\dl shit\vobdorm\VTS_01_1.VOB" "g:\dl shit\vobdorm\VTS_01_1fix.VOB" 31

now, i've never used this software before, but i do know that DOS takes issue with filenames and directories that are longer than 8 characters or have a space in them. perhaps that is the issue? also the "quotes". i've never known them to be accepted by command-line utilities, but again, i've never used this particular software.

thanx jr

i figured that was the case after my last post and i tried exactly that command...same results...input file not found

Posted by Mother on 11-10-2007 10:53 PM:

Here's a guide I wrote on another forum:

1. Make 2 new folders on your hard drive (named "original" and "fixed"). Copy all the files off your original disc into the first folder.

2. Download the program VOBDNorm from here: ftp://ftp.coises.com/vobdnorm-1.0.zip, and extract the exe file into your command path (e.g. c:\windows\system32).

3. Open a command window, and navigate to where your original and fixed folders are located.

4. Type the following command:
VOBDorm original\VTS_01_1.VOB fixed\VTS_01_1.VOB 31

5. Repeat step 4 for VTS_01_2.VOB up to VTS_01_5.VOB.

6. Copy the IFO and BUP files from original into fixed.

7. Now burn the contents of the fixed folder as a DVD-video with Nero, etc...

Posted by ZootedLooter on 11-11-2007 11:24 AM:

still donging this up....so far im at step 3

....im noticing without quotes..navigating becomes a command

the folders are here
G:\DL Shit\vobdnorm\original and G:\DL Shit\vobdnorm\fixed

there is an exe file in the vobdnorm folder as well as the one i extracted into the system 32 folder

no combination of attempts worked....ive tried one line navigation and commands...then ive tried opening the exe then navigating to the vob and fixing...and some other retard shit....but i notice that you arent opening the exe file in your guide...does that make any difference?

im fooked

im gonna go lick some windows before i try this one again

Posted by Jay Are on 11-11-2007 12:27 PM:

i think i get where she's going with this.

once you have the cmp prompt open, you can run the vobdnorm software from within any directory, since you copied it to you system folder earlier.

sounds like any other DOS software, but step 3 looks like the command doesn't work unless you are actually in the orig folder that has your vobs.

that's the only thing i can think of from looking at the step-by-step that would prevent the software from finding the files. but again, my knowledge of said software is limited.

sorry i can't be of more help.

By navigate, I mean at the command prompt, type:

code:
G:

to change to the G drive, then type

code:CD DL Shit
CD {directory where you put your original and fixed folders}

to change the working directory.

Posted by ZootedLooter on 11-11-2007 05:02 PM:

ingenious

ok im moving up the steps...im at 4 now

VOBDorm original\VTS_01_1.VOB fixed\VTS_01_1.VOB 31
gets "vodb norm is not recognized as a cmd batch file and some other fuck you resonse"

lol - i loved what about bob!

on the issue, if you have already extracted to your sys32 folder, this should run. if not, put it in there and get to work on step 5 already!

im about to get this shite and try it myself...

4 is the last step needed

but the cmd mother gave me doesnt work in the context typed....

"vodb norm is not recognized as a cmd batch file and some other fuck you response"

and thanx to both of you for your time and patience with the drooler

Posted by Mother on 11-12-2007 12:18 AM:

If you put the exe into your windows/system32 folder, the only thing I can think of is that you're spelling it vodbnorm instead of vobdnorm...

Don't you need quotes around the commands/paths that have spaces?

Posted by Jay Are on 11-12-2007 07:59 PM:

ok, so i did find the forum that had the instructions that mother gave earlier (not sure, but that thread had the UN Moth3r; is that u?) and it does give the same instructions.

linky

in that case, the person instructed says it worked like a charm.

yeah that forum is a starwars fan site...its definitley our mother....so anyway the reason why it worked for this guy is cause he is not the looter

Posted by ZootedLooter on 11-12-2007 09:08 PM:

WOO HOO!!!!!

i went with the original plan and went back to the one line command and it worked....i did alittle editing on the part of the new folders and heres the one that worked....nice app mother

"G:\DL Shit\vobdnorm\vobdnorm.exe" "G:\DL Shit\vobdnorm\original\VTS_01_1.VOB" "G:\DL Shit\vobdnorm\fixed\VTS_01_1fix.VOB" 31
worked

thanx your a real mother...
and you too JR...your ok...i dont care what people say

::::::::::::::::::AAAAAAAAARRRRRRGGGGGGHHH
HHHH!!!!!!!!!!!!!!!!!!!!

mother fucker...the value of 31 is not loud enough....it doesnt seem to have changed....i dont want to lower the other values to meet it cause then the tv will hiss....i checked it with vlc...will the value read different if its on a dvdplayer?

i got worse luck than eddie mush

Give me some fuckin' credit!

Posted by Mother on 11-13-2007 09:23 AM:

This method will only work if the Dolby Digital decoder recognises and applies dialogue normalisation. All hardware decoders - DVD players or AV receivers - should do. I think PowerDVD does as well, but I'm not sure about VLC.

It also depends on what the original dialnorm value was set to. Most commercial DVDs are 27dB, but some are already set to 31dB. For these, you cannot increase the volume this way.

yes, vlc does. sounds like the dialnorm was already set to 31db. wouldn't recommend lowering the others to match, but perhaps adobe can help.

i used audition once to raise the volume on an AVI. worked great and i even took out some background noise (it was a grinding sound, but i'm sure it would work with a hiss too) and normalize the audio by itself before rejoining with the original avi.

worth a shot if all else fails...

ps - glad it finally worked - kinda

hmmmm ok lolo credit given even if you read my spot where i notice the quotes are needed ......
but truely thanx for the help

im gonna give this cunt a shot...maybe vlc dont read the dialnorm ...the vob im trying to raise is a tv rrecording...so the dialnorm is only set to what the station put out...im adding it to previous rips i made with a dvd recorder...same channnel...they mustve lowered the volume on the station that day...the other 3 videos are all at the same volume

if that dont work..im gonna upgrade to adobe audition since cool edit changed...and then its square one for the mong

.......to be continued

::::bah...no go....im gonna have to raise it from the ac3 file

Posted by Jay Are on 11-14-2007 02:44 AM:

man if there's one thing i know about CATV, it's that the ppl who own the shows do their own audio; about half actually get it right. daily i would have to explain to old ppl why some channels are louder than others, though i think they were just lonely and confused as to why some channels are louder than others.

You're going to have to re-encode anyway, you may as well work with the uncompressed audio.

Assume it's 2.0 audio as it's recorded off the TV? Should be an easy process:
1. Use PGCDemux to demux the raw audio (AC3) and video (MPEG-2) streams from the DVD.
2. If Audition won't decode AC3, convert to WAV beforehand with Azid, Besweet, whatever.
3. Normalize in Audition, save out new file as WAV.
4. Encode WAV to a new AC3 using Aften.
5. Multiplex new audio with video from step 1 to get your fixed VOBs.

Good luck!

that guide is for making 5 or 6 ch audio...

quote:
it's possible to create 6 channels that you can then encode to surround sound using AC3, DTS or other 5.1 encoders.

im thinking plugins arent for ac3...just how to prep before converting ......am i wrong?

alternatively with the apps i have installed i can strip the ac3 audio....or use vdubmpeg to extract a wave file....but i cant remux with a wav..convert wav to ac3.. or edit an ac3....

mother...do any of those apps run right off the exe?....i hate installing more shit than the unessisary crap i already have....aaaaaarrrrrgggghhhhh

No, it'll work with 2.0 audio (as mentioned above step 1).

Not wrong just... incoherent.

PgcDemux runs off the exe. Azid and BeSweet don't need installtion, they are both command line apps - but that's no problem now you've mastered VOBDNorm usage! BeSweet has more options and you can also get a GUI for it, but for simple AC3 to WAV conversion Azid will be fine.

Posted by ZootedLooter on 11-17-2007 08:39 PM:

**UPDATE**

ive spent hours on this....(because im stubborn)....i could probably just wait until it comes back on again and rerip it...but im determined...

so last night i started on your guide mother...and i played around with besweet cause i found it on my hd(from my early pal conversions to ntsc)...i used 2 methods to raise volume from ac3 to ac3....and one worked pretty good...but the sync was out after remuxing.....i used ImagoMPEG-Muxer.exe to remux...i noticed the 5 MB file was now 7MB after volume leveling and it started out of sync around a second or so...i also tried converting to wav(it self leveled the volume also)...so i instantly converted back and again was out of sync after remux

so i tried a remux with the original ac3 file...again with ImagoMPEG-Muxer...it gives an error saying that the original ac3 file is not a valid audio file...but like i said.. after volume raising i can remux...hmmm?????...too bad its out of sync

so i started from scratch and i tried this guide
http://forum.videohelp.com/topic317...%20vol%20volume
also a much better volume but still out of sync

....shit stained again

also jay ares guide is not a plugin for audition to handle ac3 files...i would still need a conversion

Posted by Jay Are on 11-22-2007 04:48 PM:

i think i gave you the wrong bookmark in my last post... sorry for the confusion.

With Adobe Audition, what you need to do is dynamics processing.

Select the entire sound file, then go to the effects menu -> amplitude -> dynamics processing. Select the 'classic softknee' preset and click OK.

This runs the file through a filter where the dynamics of the file are adjusted to fit the curve, in this case, making the softer parts louder and vice versa. If you want to strengthen or weaken the effect, you can manually adjust the curve. Don't overdo it though - it can make parts of it sound washy.

*UPDATE*

i took another shot....i reinstalled an old canopus procoder...2 i think...and i made a dvd complient mpg and used the loudness filter

THE LOOTER WINS

finafuckinly
thanx for the help and patience guys

Posted by Jay Are on 12-06-2007 03:54 AM:

great success! although i did not help in any way, shape or form, that's not how i choose to remember it.

hell i'm just glad to see another issue resolved.
