Audio channels

i’m not quite sure of how voice allocation is supposed to work on iPhone. I’ve used Wav files for my SFX in order to enable overlaps and simultaneous audio but i don’t seem to be getting that. If a 2nd audio event is triggered on the same instance of the Audio Source component the first is terminated but the 2nd doesn’t play. If it’s on a different instance then the first is terminated and the 2nd takes over. This is exactly the behavior you would expect if the audio was encoded AAC or whatever. I must be missing something.

I don’t experience anything like that; you’re using multiple distinct AudioSource components? Each one can only play one sound at a time. You can add any number to a single GameObject though.

it only does it when it gets to the iPhone - works fine in unity.

No idea then…I have several sounds playing simultaneously on the device as well as Unity.

eric, i want to try a second AudioSource component on the same GO. How do i determine which AudioSource is used when i use ‘audio.clip =’ or do i need to create a separate child object to attach it to with it’s own script?

Creating a separate child object is probably easier in some cases, but what I’m doing is basically this, with 3 audiosource components:

enum Audio {Background1, Background2, FootSteps}
private var myAudio : AudioSource[];
var backgroundLoop : AudioClip;

function Start () {
	myAudio = Array(GetComponents(AudioSource)).ToBuiltin(AudioSource);
	myAudio[Audio.Background1].loop = true;
	myAudio[Audio.Background2].loop = true;
	myAudio[Audio.Background1].clip = backgroundLoop;
	// etc.
}
