When you say "hum" - do you mean 60 or 120 Hz hum, or something else? Is the hum consistent in frequency? If so, then the technical term for what you're seeing is a "notch filter," which you can apply to the MP3's and basically drop out the narrowly selected frequency to just "cut" the hum frequency out of the recordings.
