From Utah Public Radio:
Thousands of animal and ambient sounds from 11 western states have been recorded and archived in a digital library in Utah. While fascinating in their own right, sounds can also be used to track environmental change.
Conservationists, scientists, volunteers, and state and federal agency employees have contributed over 2,600 animal sounds that are now housed at the biggest library of its kind in the west, called the Western Soundscape Archive. The project was founded by recording engineer Jeff Rice and digital librarian Kenning Arlitsch in order to document the sounds of animals living in the west and to make people aware so they will want to protect the environments where these animals live.
The digital sound archive is kept at the University of Utah’s Willard J. Marriott Library. Anna Neatrour helped develop the archive.
