Strudelkugel writes "The BBC is reporting that a Californian company has created software that can layer relevant recorded sounds over locations in Google Earth. The firm, Wild Sanctuary, has thousands of hours of recordings from all over the world. Company director Dr. Krause has spent over 40 years collecting sounds from natural and man-made habitats. '... his recordings include more than 15,000 animal noises, and sounds from a huge array of habitats, including cities, deserts, mountains and the marine environment. It is the largest library in existence of natural sound, he said. He said the idea would be to zoom-in on a particular area and then have the option to listen to the accompanying sound.'"
