One of the greatest editing discoveries I've ever made it reading my novel aloud. This is one of the last steps in the editing process that I do and it always amazes me how much I catch even after so much work by myself and my beta readers. I've even caught things an editor has missed this way.
Tip: When you think you're finished editing your novel read it aloud, either to someone or to yourself. It's important to take your time with it and not just read what your eye 'thinks' it sees, but what is really on the page.
A few friends of mine have a program that has their computer read it aloud to them. Super cool, but the computer voice would kind of freak me out. But if you're adventurous and techie enough, it's probably worth a shot.
