Jamin's actually quite good for doing this, since it's got a nice
spectrum display and interactive EQ settings. Failing that, you could
use a LADSPA filter (like "Single band parametric") and a spectrum
analyser (like Jaaa) and just tweak the filter settings until the peak
you see on the analyser disappears.

If it's really mains hum, then you can probably just cut the
frequencies below 130Hz or so.
Maybe a notch filter at 60 Hz would be even better ?
Best,
