title: Capture, modify and then output audio in electron
body: <p>I'm trying to capture, modify and finally output audio in node with <a href="http://electron.atom.io" rel="noreferrer">Electron</a> (Mac OSX). These are the steps:</p>
  
  <ol>
  <li>Capture the audio before it's output, possibly via CoreAudio.</li>
  <li>Modify the audio stream/buffer via the Web Audio API.</li>
  <li>Output the modified buffer to the sound device.</li>
  </ol>
  
  <p>I've tried <a href="https://github.com/ZECTBynmo/node-core-audio" rel="noreferrer">node-core-audio</a>. However, the most I can achieve is a rapid glitching sound. Other than this a I haven't been able to find a good solution I/O of audio.</p>
  
  <p>How can I achieve this without sacrificing sound quality?</p>
