NFS Undercover MUS format?

Welp another EA game and they changed there MUS format.

Instead there are no Mus segments inside here.

Is there any source code out there to convert mus files?
Maybe they simply used some encryption.

[OrangeC]

They are headerless mus segments i found out in that file, problem is these are alot of segments and it will take time to add a SCHII and SCCI or whatever header mus uses, i forogt how to add the ehader chunks so maybe if someone can create a header adder or something.

[Rheini]

How shall that work? WIthout headers you don't know where one sound ends and the other begins (cause I don't believe a single sounds takes up 62MB)

[OrangeC]

Well i looked in the file and it had zeroes in between the data bglocks but i dunno if they are starting or ending blocks or if they are even the starting ending points of the files,

EA did it really complicated with this stream system but its still the same EA/XA codec.

[Rheini]

Seems to be EA's strategy
I'm also fighting with an EA audio format for some time now: viewtopic.php?f=17&t=2756

[OrangeC]

So no way to figure out these headers i presume?

[Rheini]

Well, I guess either they are saved in another file or all files use a defined common format.

[OrangeC]

There are also MPF files but they dont contain the MUS SCHII headers.

[Rheini]

Well if you knew which codec is used, you could probably convert it. Did you try any tools?

[OrangeC]

It stil uses EA/XA codecs, same codec used in other MUS files its just the stream system is differnet, no headers, and we all know how MUS has many segments of mus files inside a bigfile, but without headers, theres nothign to scan them with.

I aslo tried to use EA's Sound exchange program but thats to confusing for me.

[Rheini]

Well what about the tools created for previous games, shouldn't it be easy for their developers to support this game as well?

[OrangeC]

That is the problem, no tools can support can support this yet until someone figures out how the stream system works. It needs the headers, but adding a simple SCHII header won't do it either because it needs the additonal SCCI info and all that. So its complicated for that.

But even though if someone can create a tool that decodes dead space than maybe they can do the same thing for this. I cant even do dead spaces tool on the mus file either.

Well, SCCI and SCDI are very easy, the SCHI header is the crucial part, e.g. supplying the number of samples in the stream.

But even though if someone can create a tool that decodes dead space than maybe they can do the same thing for this. I cant even do dead spaces tool on the mus file either.

Well my point was, that those who developed tools for previous games of the NfS series have a working source code for decoding EA XA ADPCM, thus it should be easier for them to write a tool for this game.

[OrangeC]

Yes thats true but i have not seen any other tools other than sound exchange.

HMM yes i dunno how many samples in a mus segment, most mus segments have a length of 2 seconds so i have no idea how many samples that have.
