I needed to aid authentication headers for my audio files i was grabbing from a external server. So now im trying to use ajax, i can grab the files fine, but i cant set them as the media source for my player. How do you approach setting a ajax loaded file as a audio source?

EDIT

Ended up fixing it in case someone es back this way.

if (this.mAudioPlayer.canPlayType("audio/mpeg")) {
    this.mExtension = '.mp3';
}else if (this.mAudioPlayer.canPlayType("audio/ogg")) {
    this.mExtension = '.ogg';
} else if (this.mAudioPlayer.canPlayType("audio/mp4")) {
    this.mExtension = '.m4a'; 
}

this.CreateAudioData = function() {

    //downloading audio for use in data:uri
    $.ajax({
        url: aAudioSource + this.mExtension + '.txt',
        type: 'GET',
        context: this,
        async: false,
        beforeSend: function(xhr) {xhr.setRequestHeader('Authorization', window.userId);},
        success: this.EncodeAudioData,
        error: function(xhr, aStatus, aError) { HandleError('Audio Error: ' + aStatus); }
    });
};

this.EncodeAudioData = function(aData) {
    //this.mAudioData = base64_encode(aData);
    this.mAudioData = aData;

    if (this.mExtension == '.m4a') {
        Debug("playing m4a");
        this.mAudioSrc = "data:audio/mp4;base64," + this.mAudioData;
    } else if (this.mExtension == '.ogg') {
        Debug("playing ogg");
        this.mAudioSrc = "data:audio/ogg;base64," + this.mAudioData;
    } else if (this.mExtension == '.mp3') {
        Debug("playing mp3");
        this.mAudioSrc = "data:audio/mp3;base64," + this.mAudioData;
    }

};

this.play = function() {

    if (this.mAudioPlayer.src != this.mAudioSrc) {
        this.mAudioPlayer.src = this.mAudioSrc;
    }
    this.mAudioPlayer.load();
    this.mAudioPlayer.play();
};

Had to do asynch:false, otherwise i would get a small chunk of the audio instead of all of it. Though removing the asynch made debugging easier in the end.

Are you actually downloading the file, or returning it in base64 encoded format (i.e. as a Data URI)?

Changing the source of an audio element via JavaScript is quite straightforward.

<audio id="myAudio" controls />

And then once you have the source,:

var audio = document.getElementById("myAudio");
audio.src = myAudioFile;
audio.type = "type/ogg"; // ony showing an OGG example here

if (this.mAudioPlayer.canPlayType("audio/mpeg")) {
    this.mExtension = '.mp3';
}else if (this.mAudioPlayer.canPlayType("audio/ogg")) {
    this.mExtension = '.ogg';
} else if (this.mAudioPlayer.canPlayType("audio/mp4")) {
    this.mExtension = '.m4a'; 
}

this.CreateAudioData = function() {

//downloading audio for use in data:uri
$.ajax({
    url: aAudioSource + this.mExtension + '.txt',
    type: 'GET',
    context: this,
    async: false,
    beforeSend: function(xhr) {xhr.setRequestHeader('Authorization', window.userId);},
    success: this.EncodeAudioData,
    error: function(xhr, aStatus, aError) { HandleError('Audio Error: ' + aStatus); }
  });
};

this.EncodeAudioData = function(aData) {
  //this.mAudioData = base64_encode(aData);
  this.mAudioData = aData;

  if (this.mExtension == '.m4a') {
    Debug("playing m4a");
    this.mAudioSrc = "data:audio/mp4;base64," + this.mAudioData;
  } else if (this.mExtension == '.ogg') {
    Debug("playing ogg");
    this.mAudioSrc = "data:audio/ogg;base64," + this.mAudioData;
  } else if (this.mExtension == '.mp3') {
    Debug("playing mp3");
    this.mAudioSrc = "data:audio/mp3;base64," + this.mAudioData;
  }

};

this.play = function() {

   if (this.mAudioPlayer.src != this.mAudioSrc) {
       this.mAudioPlayer.src = this.mAudioSrc;
   }
    this.mAudioPlayer.load();
    this.mAudioPlayer.play();
};
