I purchased a song from AudioJungle and unfortunately it has some type of crackle artifact that I can't seem to remove. Here's a brief clip of the audio:

You can hear what almost sounds like a vibration on the right channel. I really don't know of a better way to describe it or what the proper term for this is (which makes it difficult to search for). Is there a way to remove this with Audacity or a similar program?
