<p>Below I've included a link to a video demonstrating my problem. The audio sounds fine until I put it into lightworks with another audio track and begin editing. The first clip is both audio tracks together, the second is the top audio track, the third is the bottom audio track, and the last is what it's supposed to sound like.</p>
