Cfgsfx parameters

[mcnorth 0]

Can anyone tell me what the parameters in this line mean?

empty[]={"","","","",1,30,90};

It comes from the following paragraph in a Description.ext file and is related to using custom sound effects.

class CfgSFX

{

sounds[]={"PSG", "mg"};

class PSG

{

sounds[]={"sound1"};

name="PSG";

sound1[]={"PSG.ogg",0.100000,1,0.5,0,2,5};

empty[]={"","","","",1,30,90};

};

};
