Actually it is useful for volume normalization, in those cases where the
overall sound level is either too low or too high. I have used Clément's
first patch set for over 2 weeks now on about 200 videofiles with an
average duration of 1 hour. It worked exactly as what we expected:
lowering the sound level of a few recordings and increasing the volume
of most recordings.
