NOTE: The Gate Start and Gate Stop positions in the table above can
be expressed in a number of different ways. The usual way of
representing theses positions is based on the sound path. It might
also be useful to express them relative to the depth, the true depth
or the surface distance. This allows you to better understand which
part of the piece being expected is covered by the gate.
