The Guardian’s Science Weekly podcast has an excellent interview with field recording legend Bernie Krause.
Bernie Krause has been recording wild soundscapes -- the wind in the trees, the chirping of birds, the subtle sounds of insect larvae -- for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's symphonies, from the grunting of a sea anemone to the sad calls of a beaver in mourning.
Bernie Krause has been recording wildlife sounds, or "soundscapes," for over forty years. He's amassed the largest archive in the world, and in doing so, can chart how wildlife sounds have changed over the course of climate change.
