title: What audio file types (e.g., mp3, ogg) are supported by Mobile Safari and HTML5 iOS web apps?
body: <p>There are many SO questions about playing audio files on Mobile Safari, but searching on SO and Google doesn't yield a comprehensive, updated list of audio files supported on Mobile Safari.</p>
  
  <p>Anyone know what the current list of supported audio files is?</p>
  
  <p>We're building a web app for the iPhone.</p>
  
  <p>Thanks!</p>
