title: Capturing Audio signals in Qt
body: <p>I was wondering if it is possible to capture a copy of the audio output in Qt so I can process it. <a href="http://doc.qt.io/qt-5/audiooverview.html#monitoring-audio-data-during-playback-or-recording" rel="nofollow noreferrer">Here</a> they said it's possible to monitor the playback, but I think it's only possible if you use a self made music player, which I don't want. I want to capture the signal from no matter where it is player (youtube, spotify, facebook, etc.). Is there a way to analyze this data with Qt? Is it possible to set my output of my soundcard as a QMediaSource?</p>
  
  <p>Thank you in advance.</p>
