There was a little bit of odd buzzing on "C'mon! Don't be like that, honey."
after reviewing the audition, I'm not sure what that was. I've never had that problem before and it was most likely something as simple as me accidentally bumping my mic stand.
I think I've had it happen to me before, too. The best way to prevent this is to simply listen back to what you recorded before exporting it to a WAV or MP3. It helps if you do a small amount of editing/trimming to make what you recorded sound as good as possible for the director of whatever project you're auditioning for. And even if you don't get a part, your submitted audition can be listened to by other potential directors for them to consider you for other projects!
