UbiSoft Audio Stream Decoder

[clayman]

Hi Zench, and thanks again for your tool. A quick one -- Does it support Prince of persia 2008 .forge files? I'm dying to be able to extract the music from the game.

I don't know. It's probably like Assassin's Creed, doable but very very difficult. I'm probably not a good person to ask because I don't have the game. Perhaps Kataah can help you? We were just trying a few posts ago but I'm not sure what the verdict was. But hey just give it a shot and see if it works.

So if anyone wants to decode the voice tracks from SC1 PC (which is the only place I saw it), just tell me.

I want more than anyother sound streams! Coz I'm going to translate speeches for the game, so can I extract and import with your tool?

Hello zench i took a look at double agent for 360 and it seems to use a different ubi stream version rather than the pc version.

i provided the SS4 file below, this seems compressed as the pc's is 1gb, this is like 300mb.


Could it be XMA mixed?

Yes. Here's a tool I made to more or less decode it automatically. First do a layer extract on the big file, then extract this ZIP to a directory with towave, and then run DecodeCurrentDir. It's more of a hack so it doesn't work 100 percent of the time but it should be okay.

Thx zench.

BTW will this work for other headerless xma's if i can edit the batch file?

plz Zench make so to extract wav/import in 1st splinter cell game's sound speech files, i want to translate it

[Zench]

I suppose it might. It just looks for the 08 00 00 00 pattern in the file and replaces what was before it with a generic header.

Don't worry, I haven't forgotten about you. I know it's been a long time, but I've been very busy recently so I just haven't had time to work on it. I assure you, it may take a long time (being a few months or more), but I will finish it.

Edit: Fixed little mistake in the search pattern.

I suppose it might. It just looks for the 00 00 00 08 pattern in the file and replaces what was before it with a generic header..

Tried some hacks but didnt seem to work. it just generated the header only in the output xma file, i might be doing soemthing wrong but not sure.

My file only has the stream id at the beginning.

[Zench]

I don't know if this will help or not but it actually searches for 08 00 00 00 with the 08 at the beginning, not the other way around like I wrote before. And that pattern has to be on an offset that is a multiple of 4 (for example 0 4 8 ...).

[OrangeC]

Your right, however there are other xma types with different patters to decode from, like 1C 00 00 00 ect ect.

This tool has a lot of potential though, its such a pain doing headerless xma's one by one then renaming the decoded file again after you convert.

Okay i have used the maki plug in to extract the BAO's it is indeed xma data, and the patter retaisn the same as zench said, so i put in the xma header before the 08000 pattern and it converted one of the files, i dont know how it willl work for interleaved files, but i will try.

EDIT: Okay interleaved streams didn't decode, i think this is our main problem here.

This is more of an XMA issue rather than a UbiSoft stream issue, right? I really don't know that much about XMA. What we need to do is to parse the headers, I think. Sorry that I haven't been working on this.

Status update for SC1 voice audio: I'm about 75% done with the decoder. There is still a little bit of noise in the decoded audio which I have to locate the source of.

Thanks Zench! I'm just finished translating Splinter Cell 1 text and waiting you to finish it,

See your P.M.
