If you did not mix the sound of the two mics, but left
each independent on a channel, the solution is easy (a
mix in post) - but if they are now integrated from mixing
while shooting, you would need to try various signal-processing
tricks to see if you could improve the track (expanding
the lower levels, noise-reduction, gating - mixed with
original?)
