in the testing.cbf there are only a few sounds of the nature looped folder not all..
The main thing with an addon is, that Vietcong only needs to read what is altered.
I modified the files that are in the addons, thats al i need.
The key is that you locate sound files in a map you dont want, you create a fake wav file, give it the name of the ones you want to be silenced, and stcik them in your addon.
what exactly are we listening for?
silence
EDIT:
its possible you still hear some sounds, i only "removed" the ocean, and the crickets.
