Audio in online game

Hi, I'm developing a simple third person online shooter with an non-authoritative server. I've synchronized players and projectile view. For now each player listen fire effects of each other players in the scene. How can I make listen to player only sound effects of fire and projectile in the near or at least make listen only sound effects of fire that are in the camera view? This is the code of fire RPC:

function Update { if( Input.GetButtonDown( "Fire1" )) { var viewID : NetworkViewID= Network.AllocateViewID(); networkView.RPC("Fire", RPCMode.AllBuffered, viewID, transform.position); } }

@RPC function Fire (viewID : NetworkViewID, location : Vector3) { // Instantate the prefab locally var instantiatedProjectile : Rigidbody = Instantiate( projectile, transform.position, transform.rotation ); instantiatedProjectile.velocity = transform.TransformDirection( Vector3( 0, 0, speed ) ); AudioSource.PlayClipAtPoint(bulletClip, transform.position); Physics.IgnoreCollision(instantiatedProjectile.collider, transform.root.collider); Destroy(instantiatedProjectile.gameObject, 1); var nView : NetworkView; nView = instantiatedProjectile.GetComponent(NetworkView); nView.viewID = viewID; }
