script to read the time on an audio file
// Create a non-dom allocated Audio element
var audio = document.createElement('audio');
// Add a change event listener to the file input
document.getElementById("fileinput").addEventListener('change', function(event){

// Obtain the duration in seconds of the audio file (with milliseconds as well, a float value)
var duration = audio.duration;
// example 12.3234 seconds
console.log("The duration of the song is of: " + duration + " seconds");
// Alternatively, just display the integer value with
// parseInt(duration)
// 12 seconds
},false);
