title: WebRTC - Saving audio stream into file
body: <p>I have two WebRTC peers SENDER (Chrome) and RECEIVER (C++ application).</p>
  
  <p>SENDER initiates a WebTRC connection and sends or streams audio data to RECEIVER.</p>
  
  <p>I need to save the resulting audio data (I don't know typically how long this will be but let's say less than 3 minutes) into a file for later processing.</p>
  
  <p>But I am not sure which end I should do this.  Is it better to save audio on the SENDER side and then send it to RECEIVER?  Or is it better to stream audio from SENDER to RECEIVER and save that stream as it comes into a file on the receiving end?</p>
