Ghost breath

ok now yesterday ,I was looking for some sounds to mix some musics in crossfire folder.
I Remenber how did i kill ghosts with it, i mean their Breath.
Ok now u can only ear ghost breath if u r near them and if they r skilled they will kill u.
If you are far u will ear but very, very low then if we could change its volume or frequency we just got our selves a good distance of security to ear them , and offcourse Spray the sh*t out of them

So im asking if some one can look for their breath and tell me where it is ...

This is just a thought ... dont flame

it think its on the rez files
