New Config Line?

[bigpickle 0]

Hey I found this new line inside the SoundShader config for the Katiba rifle while working on some audio. Its the customCategory line.

 

    class Katiba_Tail_SoundSet: Rifle_Tail_Base_SoundSet
    {
        soundShaders[]={"Katiba_tailTrees_SoundShader","Katiba_tailForest_SoundShader","Katiba_tailMeadows_SoundShader","Katiba_tailHouses_SoundShader"};
        volumeFactor=1.3;
        customCategory="limit2";
        frequencyRandomizer=1.5;
    };

 

Any ideas what it does?
