The short sound sample released on NASA's website was compressed, so the twenty-seven minute recording plays back in just seventy-three seconds. The frequencies of these emissions are outside the human audio frequency range and have been shifted downward by a factor of 44.
Now, listen to the first few moments of this short excerpt from the classic 1956 science fiction movie Forbidden Planet.
(Forbidden Planet excerpt)
The soundtrack for the movie was created by Louis and Bebe Barron. The film represents the first instance in which a movie was scored entirely with electronic music. Louis Barron constructed electronic circuits that generated the sounds; most of the tonalities were generated using a ring modulator. In creating the electronic circuits, Barron used the equations in Norbert Weiner's 1948 book Cybernetics: Or, Control and Communication in the Animal and the Machine.
