I have successfully ripped sounds from a mod (specifically Bdub's helicopter sounds) and they seem loud when played on VLC. In-game they sound so tame.
I don't think editing the WAV file and reimporting will fix it. It has something to do in the game instead.
Is there a way to increase the volume of sound via xml?
Most of the changes that can be done via xml upon inspection only relates to stealth, or am I misunderstanding how it works?
