title: How can I Remove a Wandering DC Offset from an Audio Clip?
body: <p>I've licensed some audio clips, but some of them come with what I have learned is a "DC Offset" that should normally have been removed during production.</p>
  
  <p>Audacity's "Normalize" filter is able to fix a static DC Offset, but after applying it to my audio clips, I noticed that their DC offset varies (within 0.5 seconds it could go from 0.05 to 0.03 along a normalized amplitude range). For example:</p>
  
  <p><img src="https://i.stack.imgur.com/xhD4J.png" alt="Wandering DC Offset"></p>
  
  <p>To the left, silence is at 0.02, to the right, it's at 0.00 - this is after normalization by Audacity.</p>
  
  <p>With me not being an audio engineer and not having any professional tools, is there a way to fix this?</p>
