title: Build HTML5 audio player with web audio API
body: <p>The <code>&lt;audio&gt;</code> tag streams the input and plays it. This is not suitable when we have to sync multiple audios. Explained here in SO answer <a href="https://stackoverflow.com/a/16498601/287100">https://stackoverflow.com/a/16498601/287100</a></p>
  
  <p>So I would like to build an audio player which doesn't stream audio rather it downloads it or uses web audio API. I know how to load audio using API but don't know how to hook up it with progress bar with seeking feature.</p>
