Interview with audio pioneer Jim Metzner.

"Sound allows the listener to experience a story. Holistically. So
you hear a sound and information about a subject that words can
only allude to. Sounds can give you another quality of impression."
These are the words of Jim Metzner, who is a longtime expert in
telling stories with sound. His hallmark is the distinctive use of
ambient sound. Beside his productions for National Geographic or
NASA Jim Metzner has been producing a short format science program
since 1988 with more than 6,000 episodes. He acoustically deals
with environmental issues all over the world. More than 250 public
and commercial broadcast outlets worldwide currently air “Pulse of
the Planet”. More than one million listeners per month hear each
episode.
