Why audio isn't playing when downloaded ?

Hello. I'm trying to download at runtime, various audio file format : Mp3 , Ogg, Wav but I can't play it at runtime.

This is my code:
WWW data = new WWW(audioURL); yield return data;
AudioClip downloadedClip = data.GetAudioClipCompressed(false, AudioType.OGGVORBIS) as AudioClip;
if (downloadedClip != null)
{
_audio.clip = downloadedClip;
}
...

This code to play Audio:

public void PlayAudio() {
// Here clip is play
if (_audio.clip != null && _audio.isPlaying == false)
_audio.Play();
else
Debug.Log("Background music not present!");
_audio.loop = true;
}

I've also try to download Audio using this code:

using (UnityWebRequest www2 = UnityWebRequestMultimedia.GetAudioClip(audioURL, AudioType.OGGVORBIS))
{
yield return www2.SendWebRequest();

if (www2.isHttpError)
{
Debug.Log(www2.error);
LogAdd(www.error, true);
}
else
{
AudioClip downloadedClip = DownloadHandlerAudioClip.GetContent(www2);
_audio.clip = downloadedClip;
}
}

I can't use AssetBundle because my web app is interactive: user can upload file (audio) then they will be reproduced later.

Can you help me ?

Thanks

 

EDIT: When uploading Mp3 error is: Streaming of 'mpeg' on this platform is not supported UnityEngine.Networking.DownloadHandlerAudioClip:GetContent(UnityWebRequest)

 

EDIT: no way to make it works on WebGL/browser. Using Editor it seems to work (specially with OGG). But the same code, same build, not works on webgl...

 

If you want to download music and stream it, do it in your index.html. You will need to `play` inside a click handler.
