CfgAmmo class attributes

[A.Cipher 4]

Hello there ,

 

I have a question about some attributes of the CfgAmmo conf class , these attributes are soundHit[] ,soundFly[] and soundEngine[].

here some example of use of these

 

soundHit[] = {"a3\sounds_f\weapons\Explosion\gr_explosion_1.wss", 15.8489, 1, 1000};
soundFly[] = {"a3\sounds_f\weapons\Cannons\cannon_30mm.wss",1,1};
soundEngine[] = {"a3\sounds_f\weapons\Cannons\cannon_1.wss",1,1};

I want to know about these "number" paramater signification for each one of them.

 

I googled them but with no luck :'(

  

THX :)
