How to load a file into a html5 audio tag

Question

How would a I load a audio file from a <input type="file"> tag into a audio tag? I have tried :

<input type="file" id="file"></input>
<script>
var file = document.getElementById("file");
var audio = document.createElement("audio");
audio.src = file.value;
document.write(audio)
</script>

I believe it will satisfy your needs. First, the file input needs to be bound via JavaScript or jQuery (if you prefer). You can use Blob ^{browser support}

The following is a very basic example;

<input type="file" id="file"></input>
<audio id="audio" controls autoplay></audio>

We bind the #file for changes using AddEventListener as below

// Check for BlobURL support
var blob = window.URL || window.webkitURL;
    if (!blob) {
        console.log('Your browser does not support Blob URLs :(');
        return;           
    }

document.getElementById('file').addEventListener('change', function(event){

        consolePrint('change on input#file triggered');
        var file = this.files[0],
         fileURL = blob.createObjectURL(file);
        console.log(file);
        console.log('File name: '+file.name);
        console.log('File type: '+file.type);
        console.log('File BlobURL: '+ fileURL);
        document.getElementById('audio').src = fileURL;

});

Or the other hand, here's a nice and more interactive example I created

<iframe style="height:600px;width:102.7%;margin:-10px;overflow:hidden;" src="//jsfiddle.net/adamazad/0oy5moph/embedded/result,js,html,css/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
