It took archivists with the Macaulay Library at the Cornell Lab of Ornithology, over a dozen years to fully digitize and make available online the world’s largest natural sound collection. The collection dates back to 1929 and contains nearly 150,000 digital audio recordings, equaling more than 10 terabytes of data, with a total run time of 7,513 hours. About 9,000 species are represented. There’s an emphasis on birds, but the collection also includes many sounds of the salty animals – whales, walruses and more.
