How to play wav file from Web?

Questions & Answers
1

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?

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"));

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);
}
