Horrible Audio Quality (what can I do about it?)

I recently exported this new video I was making. The audio was reasonably good in the original footage, and also reasonably good while playing in HitFilm. After the export however, the quality was drastically reduced. It was actually sounding bad. I was making this video for YouTube, so now I can't upload till I get this right. Please help!
