Hi
Thanks for all your replies.
I did some further testing. I rased db to + 100 on a soundfile which is low on volume inside the mission in the description. I saved . . . restarted ArmA once again. No audible changement to hear therefore I guess you can't raise volume of an audiofile by simply modifying db value in the description.ext. At least for me it doesn't work. In case I have a low volume audiofile I have to re-edit the volume with my soundeditor. That's my conclusion . . . I don't know if anyone else experienced the same or differently.
Please give some feedback in case someone did some experimenting on this matter in question.
