Yes it does. You need to define the sound in Description.ext using:
class CfgRadio. For example:
class CfgRadio
{
sounds[] = {};
class Civi2_11
{
name = "";
sound[] = {"\sound\Civi2_11.ogg", db-100, 1.0};
title = "Well all the civilians are now safe in the lodge. I am ready for your orders.";
};
class Civi2_12
{
name = "";
sound[] = {"\sound\Civi2_12.ogg", db-100, 1.0};
title = "I am now at the lodge, but I am afraid we suffered some civilian casualties on the way. I am ready for your orders.";
};
};
Note that there is a slight difference between this and defining sounds. For CfgRadio you use title but for CfgSounds you use titles
You script the sound as follows:
unitname sideRadio "Civi2_11"
This will give you the standard OFP radio static and click at the end.
For a more pronounced radio interferrence what I have done in the past use some sound editing software that comes with the Roxio CD/DVD buring package. This provides the ability to generate hiss, clicks, static etc. I use this on my voice file. I then tune a shortwave radio in between stations and record the sound. I then use Dexter to merge the two sounds (Roxio doesn't provide the merge capability). I then use this as a normal sound in the mission.
