title: Redux or Pub/Sub?
body: <p>I have a react app which will record audio.
  When the user presses a button the component should cause it's parent to run a stopRecording() routine, resulting in saving the file and some json data about conditions and triggering a user flow.</p>
  
  <p>I'd been looking into Redux which seems fine for JSON data but I'm less sure about audio files.
  But does Redux fulfill the purpose of pub/sub for notifying components they should do stuff.</p>
