Question by sugitashannon · Mar 27, 2015 at 06:21 AM · wav

How to play wav file from Web?

Hi there.

I'd like to play wav file from Web URL.

I attached AudioSource componento to my GameObject .

And I created the method.

 private void PlaySoundFromURL (string url)
 {
     // url = System.Uri.EscapeUriString (url);
     Debug.Log (url);
     WWW www = new WWW(url);
     audio.clip = www.audioClip;
     audio.Play();
 }

And, I tried it

 PlaySoundFromURL ("http://www-mmsp.ece.mcgill.ca/documents/audioformats/wave/Samples/AFsp/M1F1-Alaw-AFsp.wav");

But, the sound file didn't play.

Could you tell me how to play the file?

Thank you.

I found what I was mistook.

I attached $$anonymous$$ain Camera and I could listen. Because, Audio Listener was far from audio source... and yield was required.

You should wait for the file to be downloaded:

 bool Play = false;

 private IEnumerator PlaySoundFromURL (string url) {
      // url = System.Uri.EscapeUriString (url);
      Debug.Log (url);
      WWW www = new WWW(url);
      yield return www;
      Debug.Log("The file has been downloaded, playing it");
      audio.clip = www.audioClip;
      play = true;
      Debug.Log("Audio played");
 }

 AudioSource audio;

 void Update() {
     if (play) {
         if (!source.isPlaying && source.clip.isReadyToPlay) {
             audio.play();
         }
     }
 }
 
 public void PlayTheSound(string URL) {
      StartCoroutine(PlaySoundFromURL(URL);
 }
 
 string url = "http://www-mmsp.ece.mcgill.ca/documents/audioformats/wave/Samples/AFsp/M1F1-Alaw-AFsp.wav";
 
 void Start() {
      audio = GetComponent<AudioSource>();
      PlayTheSound(url);
 }

Hi

You should read reference. http://docs.unity3d.com/ScriptReference/WWW.html


 using UnityEngine;
 using System.Collections;
 
 [RequireComponent(typeof(AudioSource))]
 public class Getaudio : MonoBehaviour {
     public string url;
     private AudioSource audio;
     // Use this for initialization
     IEnumerator Start () {
         audio = GetComponent<AudioSource>();
 
         while(true){
             if(Input.GetKeyDown(KeyCode.Space)){
                 yield return StartCoroutine("PlaySoundFromURL",url);
             }
             yield return null;
         }
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     private IEnumerator PlaySoundFromURL(string url)
     {
         // url = System.Uri.EscapeUriString (url);
         Debug.Log (url);
         WWW www = new WWW(url);
         yield return www;
         audio.clip = www.audioClip;
         audio.Play();
     }
 }

You can't play an audio file from the web instantly! You'll have to wait till it gets downloaded and then play it. To do this, you can use a coroutine:

 IEnumerator PlaySoundFromURL (string url)
 {
     WWW www = new WWW(url);
 
     while (!www.isDone)
         yield return null;
 
     audio.clip = www.audioClip;
     audio.Play();
 }

To play it:

 StartCoroutine (PlaySoundFromURL ("http://www-mmsp.ece.mcgill.ca/documents/audioformats/wave/Samples/AFsp/M1F1-Alaw-AFsp.wav"));
