How to add 5.1 (6 channels) to a VOB file

[samjo511]

Hello,

before i start, this forum is awesome..
worth joining here.

so... im seeking for a best solution to add 5.1 (6 channels) to a VOB file.
i hv read some tutorials from this site.. but i cant get it. coz im so noobish in this.
the purpose i wanna do this coz im a BGM (background music) ripper. I like to rip the BGM of a movie without voice. It can be only done extracting 6 WAV channels from a vob file. but Im facing a problem when a dvd comes without these option.
it only hv 2 channels.
so would someone plz help to solve this.

1. Demux the VOB (DGIndex, File->Save Project and Demux Video, among other ways)
2. Remux, substituting your 6 channel AC3 for the original (Muxman)

I'm answering how to replace the current audio with DD 5.1 audio. If your question is how to remove the voice from DD 2.0 audio, then I'd say forget about it.

[samjo511]

thanks manono
wil try now.. n give my result

[samjo511]

i cant understand the second step

[manono]

Geez, open Muxman. Add the M2V video file. Add the DD 5.1 audio file. Give it a Destination. Push the 'Start' button.

[samjo511]

ok. i got u now.
should i add the same ac3 file 6 times ( stream) ?

[manono]

No, why would you do that? Have you seen DVDs before with the same audio track repeated 6 times?

[samjo511]

ok let me explain in my term..
all i want is the vob file should show like the 1st pic.. (5.1)
but some dvds are not encoded with that option n show as 2nd pic.
all i want to do is make the vob file as the 1st one. (adding 6 channels)

[manono]

I already said to load a DD 5.1 audio file. If the audio is really DD 2.0, why on earth would you want to make it DD 5.1? There are posts around here explaining how to convert DD 2.0 to fake DD 5.1. Look around. It's a stupid idea, though, if you ask me.

Samjo511, from your first post it sounds like you're used to ripping 6 channels from a 5.1 track, so that you can capture and isolate just the music, without any vocals. You then want to add the results back into the movie as a 5.1 track. The problem is that you've come across a soundtrack that only has two channels, so you want to know how to do what you're used to doing with a 6-channel track, but you want to do it to a 2-channel track instead. Is that the case? If so, then Manono is right... you can pretty much forget about removing the vocals...
Well, actually, if it's a true Stereo recording, you might be able to minimalize the vocals, but not remove them completely. It's not worth the trouble. You'll end up very frustrated.
Again, Manono is right... you can create a fake 5.1 from a 2.0 source, but there's really no point.
If you're still interested, have questions, comments or whatever, it'll help greatly if you're as specific as possible about what you usually do, what methods you use, what you expect to end up hearing, how you want to use the resulting track(s) and so on.

This won't work.

In (some) 5.1 channel audio you can extract the separate channels to get just the music track.

In stereo, 2-channel, audio the music is mixed with the speech and other sound effects; you cannot extract it (not cleanly or easily anyway).
You cannot convert stereo to 5.1 and get the same channel separation. You can easily mix sound; you cannot easily unmix it.

There are some audio tools you can try to reduce the speech part of the soundtrack, some people do this to make cheap Karaoke tracks, but it damages the music and you can always still hear the speech and other noise.

But again, it doesn't work perfectly.
Better to spend your time looking for the OST CD.

thanks for the reply takearushfan n AlanHK

actually i use this software to do my stuff

DVD Audio Extractor

1) After opening DVD Audio Extractor, in DVD-Video source choose File-Open single DVD VOB file. After choosing the file from DVD click next.

2) In Output Format choose WAV.

Sample rate: 44100Hz
Channels: All 6 channels
Bits per sample: 16 bits

Tick "Save each channel into separate file"
Click Next

3) Choose output location, Tick "Save each channel into separate file". Click next.

so... i mess up when there is no option when selecting the channels to 6 channels. it only shows stereo and mono.
thats i wonder that how to make a dvd file with 6 channels.
thats was my problem. im not doing karaokes.. im just ripping the background musics in a movie.
usually a dvd with 6 channels hv audio without voice in the 1st and 2nd channel. 3rd channel is only voice contained. 4,5.6th are effects.
thats y i wonder to make the dvd file into 6 channels.
any solution?

[takearushfan]

Hm. Well you're kind of confusing me by referring to each channel by number. Instead it might help to say FL, FR (Front Left, Front Right), C (Center), SL, SR (Surround Left/Right) and LFE (Low Frequency Effects). The last one is sort of a fancy was of saying "The bass/subwoofer". Typically, whenever I run across a DVD (or portion of a DVD) where you can isolate only the music, the music is stored in the Surrounds, but there are so many factors that have to do with whether or not you can isolate just the music and how the engineers decided to place the music, vocals, effects and so on in each channel. It's unlikely that the entire movie will have no vocals in those channels, which is why I said "portion" of a DVD. What film are you trying to work on? (don't worry, it's okay to say it). Unfortunately, what AlanHK said is true. If it's a Stereo recording than everything has already been mixed down into those 2 channels, so if you're lucky, all you can really do is possibly reduce the vocals, but not remove them completely. It sucks, I know. Just be glad you're not working with a Mono soundtrack... if that were the case then there'd virtually be literally no possibility of doing anything with it. I'm sorry I can't be of more help

No. I understand what you want to do, and it's impossible.

You cannot "make the dvd file into 6 channels" separated into voice, effects, music, when you only have a stereo track to start with.
The information you need isn't there.

It's exactly like saying "The total of 6 numbers is 52. What are the 6 numbers?"
There are many possible answers. An infinite number if you include decimals.

Oh... I (think) I get it now. He wants the DVD to contain 6 different streams, one for each channel...? I thought he only wanted the music and to have that be a single stream. Yikes. That makes it even worse!

I think he does just want the music, but he's used to doing that by selecting one or two tracks from a 5.1 stream (which will often work), and thinks that a stereo track can be simply be converted to 5.1, then he will apply his usual method.

The problem is that 5.1 and stereo are not the same information in different packages. The conversion is one way.

Another analogy (my last one, I promise): You can turn any meat into sausages; you can't turn sausage back into cuts of meat.

[takearushfan]

Hm. Well I guess there's no sense in trying to pinpoint what his goals/methods are 'til he actually replies, lol.

[samjo511]

Ok. Here I am after 2 years. Yes. You people were right. It is just my crecko mind where I cant understand on that time. Yes. No chance to make those vob files in 5.1 option unless it comes in that option from the manufacturer. Thanks a ton guys.

Sorry for the late reply. :P
