title: ffmpeg - Can I draw an audio channel as an image?
body: <p>I'm wondering if it's possible to draw an audio channel of a video or audio file as an image using ffmpeg, or if there's another tool that would do it on Win2k8 x64. I'm doing this as part of an encoding process after a user uploads a video or audio file.</p>
  
  <p>I'm using ColdFusion 10 to handle the upload and calling cfexecute to run ffmpeg.</p>
  
  <p>I need the image to look something like this (without the horizontal lines):</p>
