This is a question related to the game Deadly Shadows, not the separate soundtrack included.

I just noticed that the soundtrack that came alongside Deadly Shadows is kind of muffled sounding, as if it was recorded from an outside source.

I was wondering if it was possible to directly extract the soundtrack from the game itself, and if this would make any difference to the sound quality.

Thanks for the help! BTW my personal favorite track is tied between Southquarter and Clocktower :)

Yes, it is possible, and it most likely would indeed make a difference since the original files from the game are in ogg format instead of mp3.

However you'll need to use special tools for that.
To this day, the only one I am aware of to automatically perform the task is called deconcat and can be downloaded from here: http://trollz1.free.fr/?p=deconcat
Be warned though that it is to be used from command line, which most people may not find very user friendly.

If you're not afraid of that though, here's a quick way to use it :
- create a directory where you want to have the files extracted
- download deconcat.exe and deconcat.conf to this directory
- from command line, get into that directory
- run the following command line :
deconcat "path_to_your_thief3_folder\CONTENT\T3\Sounds\SchemaMetafile_DVD1.csc"
- do the same thing with SchemaMetafile_DVD2.csc and SchemaMetafile_DVD3.csc

It should create about 20 thousand .ogg files. Typically he smaller ones contain voices, while the larger ones (those above 400 Kb) mostly contain the game's music tracks or long speeches (such as mission intros).

Your advice sounds pretty solid. I'm gonna double check with some taffer friends before trying it, but just to check here:
Would these .ogg files be compatible with Windows Player Media? Would coverting them to MP3 have the same effect as the soundtrack that was already given?

Thanks again!

I don't usually use Windows Media Player so I just tried reading one of the tracks with it (version 12) and even though it gave a message about the file extension not being recognized, it still read OK.

About what converting to mp3 would do to the tracks, I guess it would depend on which quality settings you use.
