Blue Snowball Microphone and Mixcraft 5.2?

Okay, so i'm trying to record my voice, but the track seems to be louder than my voice. So, I tried turning the track down, but then you can't really understand what I'm saying and I'm speaking pretty clear so I don't understand why it's not recording loud and clear. My voice is somewhat deep, so when i get too close to the mic, it makes a vibrating sound sort of after it's mixed down to an mp3 file...How can I make my voice louder and more clear without screaming at the top of my lungs and being too close to the mic, using mixcraft 5.2 and the Blue Snowball microphone?
