title: How can you only extract 30 seconds of audio using ffmpeg
body: <p>I am using ffmpeg for audio conversion. I am using this command:</p>
  
  <pre><code>ffmpeg -i file.mp3 file.wav
  </code></pre>
  
  <p>This works fine. However I only want to my output file to contain maximum 1 minute of audio. How can I do that using ffmpeg?</p>
