Audio streaming blocks unity

Unity Engine
1

I’m trying to stream a local audio file using the WWW class. The problem is that it blocks unity until it is loaded, in my case the blocking last about 5 seconds:

public IEnumerator audioThread()
{
  while(true)
  {
    if (startStreaming_ )
    {
      WWW location = new WWW("file://audio1.ogg");
      while (!location.isDone)	
      {
              print("before wait..");
              yield return new WaitForSeconds(0.2f);
              print("after wait..");			
      }
      audioSource_.clip = location.oggVorbis;
      audioSource_.loop = true;	
      startStreaming_ = false;
    }			 
    // Wait 100 msec
    yield return new WaitForSeconds(0.1f);
  }
}
void Start () {	
  StartCoroutine(audioThread());
  startStreaming_ = true;
}

I would expect that the audio would “load” in the “background”. It does not and blocks…
What is also strange is that it blocks after having called:

	      yield return new WaitForSeconds(0.2f);

So “before wait…” is printed,
then everything blocks for 5 seconds,
then “after wait…” is printed and the audio is finaly played…

I found this in the WWW.isDone scripting reference:

Have you tried using AudioClip.isReadyToPlay instead? Something like this:

var url : String;
function Start ()
{
    www=new WWW(url);
    audio.clip=www.audioClip;
}

function Update ()
{
    if(!audio.isPlaying  audio.clip.isReadyToPlay)
        audio.Play();
}

Hope it helps! :smile:
Please let us know if it did!
