title: audio progress bar in angularjs
body: <p>I'm trying to create a web audio player using angularjs. 
  I'm not using the html5 "controls" attribute for the player since I want a specific style. I have play/pause/next/prev buttons but I've been struggling trying to create an interactive progress bar. I've read different options to create "static" progress bars (for example using bootstrap) that shows the progress but the user can't seek and jump to a different part of the song. I think I'm missing something, it can't be that difficult to create a seekable progress bar. Does anybody has an idea about how this should be done? 
  thanks</p>
  
  <p>Edit: other possibility could be using some of those libraries that wrap the audio element and add functionalities. Did anybody use some of this libraries? </p>
