title: How can I get the current sound level of the current audio output device?
body: <p>I'm looking for a way to tap into the current audio output on a Mac, then return a value representing the current sound level.</p>
  
  <p>By sound level, I mean the amount of noise being generated by the output. I'm <strong>NOT</strong> asking how to get the current volume level of the output device. </p>
