Welcome to the Purdue Soundscape Ecology Project
BioScience paper - This section contains the sound files of the Pijanowski et al. (2011) BioScience article titled "Soundscape Ecology: The Science of Sound in the Landscape."
Tippecanoe Soundscape - This site contains an interface to over 32,000 15-min recordings made in 2008 at 7 sites in Tippecanoe County, Indiana. Each 15-min recording was analyzed for the amount of acoustic diversity and as well as the composition of acoustic frequencies. Recordings started at the top of every hour. The recordings were stored originally as wav files in 44.1 kHz, 16 bit format. Files were compressed to FLAC for long term storage and to MP3 for listening over the web.
La Selva Soundscape - This site contains over 9,000 recordings made in 2008 at 24 sites in the La Selva Field Station and the Braulio Carrillo National Park, Costa Rica. The sites covered a range of elevations, from 100 meters to about 600 meters above sea level.

Soundscape Tools
- Pumilio is a free and open source PHP/MySQL application for the management of sound archives and the visualization and manipulation of sound files.
- Users can plot a day (or longer) of the acoustic diversity index of the Tippecanoe Soundscape.
- Scripts in R language are available to obtain the acoustic diversity index out of wav sound files.
