Maybe. But if the info removed was masked by other, louder sounds, then
wouldn't the two in principle be indistinguishable?

Consider a visual analogy. You're mking a movie, and need to
have a set that looks like the White House. But only the front of the White House
(from a range of angles, so it's the front, and parts of the sides), the Oval Office, and
a few other administrative offices.

Someone then builds a demonstration, which is every part of the WH -- including many of the rooms,
the entire back side, the basement, etc. -- that your movie set didn't include.

There would be a lot of building there, absolutely none of which would have been relevant to the
replication of the WH in your movie.
