In Audacity you try Effect -> Normalize and tick the box that says
"Remove any DC offset".
From http://en.wikipedia.org/wiki/DC_offset :
"DC offset is an offsetting of a signal from zero. The term originated
in electronics, where it refers to a direct current voltage, but the
concept has been extended to any representation of a waveform. DC offset
is the mean amplitude of the waveform; if the mean amplitude is zero,
there is no DC offset.
DC offset is usually undesirable. For example, in audio processing, a
sound that has DC offset will not be at its loudest possible volume when
normalized (because the offset consumes headroom), and this problem can
possibly extend to the mix as a whole, since a sound with DC offset and
a sound without DC offset will have DC offset when mixed. It may also
cause other artifacts depending on what is being done with the signal."
