Does Audacity support that? I don't know, if it doesn't, get Audition (it's not free, PM me...)

Yes, the best solution is to fix the jack. And if that's outside possibility, then her options are reducing the frequency domain that the buzz occupies, in the recording itself. The acceptable effectiveness of this will completely depend on the extent at which intended signals occupy that frequency range.
I'm thinking maybe you are referring to frequency cancellation, which would use two mirrored range of frequencies and invert phases, thus canceling that freq range out... which achieves the same thing as EQing a frequency range out........
Adobe Audition calls that "creating a noise floor"?
What a horrible choice of terminology.
