I don't think that's taking into account the harmonic frequencies. The 50Hz buzz is not a sine wave.

  And its frequency is not constant. You'd have to have some kind of adaptive comb filter to remove the original buzz with all its components. I've a feeling that would be tricky to do in a way that doesn't scream "photoshopped" (or whatever the equivalent is for audio).
