I challenge you to import these two files into Ardour (onto two tracks)
and invert the phase of the other track to hear the difference between
the files. By adjusting the level of one track about 1.5 dB, the tracks
should cancel each other out. It will be hard to hit the exact right
level for total cancellation, but you should notice, that nothing stands
out from the difference signal.
