Medal of Honor Frontline Sounds?
 

Is it possible to get sounds from MOHFL and transfer them onto the CPU and make a mod out of it?

probably not, the only way you could do it is to record the sound effects diretly from the game into some kind of audio editor, some thing like Audacity or Pro Tools LE. The bigest problem you are going to run into is trying to remove the ambient sound effects from the gun sound effect that you are trying to isolate. What you will probably end up doing is distorting the sound effect so much, by using what ever EQ or editing you end up using that the effect will be unusable or just sound terrible. Some might work but I think most won't. It would be an interesting experiment to say the least.
