title: How do I get ffmpeg to correctly output this wav file?
body: <p>I'm trying to concatenate a lot of wav files and it far exceeds the 4GB limit. </p>
  
  <p>Someone mentioned somewhere that the <code>-rf64 auto option</code> will solve it but -rf64 isn't recognized in the command line. What do I need to do in this command line to solve this problem?</p>
  
  <pre><code>ffmpeg -f concat -rf64 auto -i mylist.txt -c copy output.wav
  </code></pre>
