Saving multiple channels in one OGG file [CLOSED]

[Roadhog360]

So, I've been trying to save an OGG file with multiple channels.
Basically, I am trying to edit this OGG file, but can't get it to save the way it was.
When I open the file, I get this:

So, I select everything and press OK.

Now, as you can see, there are two channels visible in this screenshot (In total there's about 18).
Each one has a different song.
What I am trying to do is save the OGG the way it was by having those multiple channels.
Every time I save through exporting, it 'squashes' all 18 or so channels into one, causing it to be one glob of about 18 songs at once.
If I save through export multiple, it saves each channel as a separate OGG file.
How can I save the channels/indexes in the OGG file like it was when I opened it?
I saw a thread about this, but it didn't get a good answer, so I'm here to explain it in more detail. Person also said it was MOGG, but the format is actually OGG.
The person who replied also said to go to a gaming forum, but didn't link any forums or anything, so it wasn't very helpful.

Actually, I'll opt for other formats that have multiple channels like this, I'll try to convert it back and report my results here.

To create a multi-channel file (more than 2 channels), you need to enable the "Use custom mix" option in Preferences.

It's up to you do to the research into the best forum, because if this is a MOGG file, Audacity does not support exporting as that (except for exporting multi-channel OGG). It depends where you are going to play the multi-channel OGG file that Audacity exports. It won't work in a game, if it came from a game in the first place.

Please don't misrepresent what I said. I mentioned Doom9 and AfterDawn forums.

Is there even an official specification for Mogg? Other than loads of pirate-ware, it only use seems to be used by Rock Band and Guitar Hero.

That's the problem. MOGG files are usually encrypted if they come from Rock Band/Guitar Hero, so you've already had to use unofficial software to decrypt them into something Audacity can import. That's why you're probably going to have to dig deep into gaming forums, logged into a special area, if you want to figure how to repackage a MOGG after decrypting and editing it.

There is something about the MOGG-specific headers here: http://rockband.scorehero.com/forum/vie ... php?t=7128.

It is an OGG, not an MOGG, and it came from a game, and the game reads the file this way.

Also, I just tried what you said, and it limits me to 32 channels and cuts off some of the game's channels even though the OGG file in the game only has 20.
They just only have odd numbers, here's the game's channels:

Code: Select all

1
3
5
7
9
11
13
15
17
19
21
23
25
27
29
31
33
35
37
39

But it thinks it's 39 channels and only allows channels 1-32. It saves channels 1-32, but also has even numbered channels. In a weird way...
What I mean 'in a weird way' is, the channels of an odd number are copied to the next number to 'fill' in the even numbers with the previous odd number. So the channel 2 it created uses channel 1's audio, channel 4 uses channel 3's audio, etc, so it's copied over.Z
How can I fix this?

If it's from a game as we suspected, it's a MOGG whatever it was renamed as.

To reiterate for you, Audacity supports multi-channel OGG files for playback in standard audio players.

Audacity has no way to package OGG or MOGG files that have non-standard headers and custom indices for use in games.

You may be able to "fix it" by going to the dark side of gaming forums.
