AudioSource.spread

Description

Sets the spread angle a 3d stereo or multichannel sound in speaker space.

0 = all sound channels are located at the same speaker location and is 'mono'. 360 = all subchannels are located at the opposite speaker location to the speaker location that it should be according to 3D position. Default = 0.

	// when any AudioSource goes trough this transform, it will set it as 'mono'
	// and will restore the value to 3D effect after exiting
	// Make sure the audio source has a collider.
	function OnTriggerEnter(other : Collider) {
		var audio = other.GetComponent.<AudioSource>();
		
		if(audio)
			audio.spread = 0;
	}

	function OnTriggerExit(other : Collider) {
		var audio = other.GetComponent.<AudioSource>();
		
		if(audio)
			audio.spread = 360;
	}
