Find data

The A2O provides data for hundreds of acoustic sensors across seven Australian ecoregions. The A2O data include acoustic recordings collected by site sensors as well as site information, such as vegetation cover, landform, disturbance and photopoints. These data are available for use under CC BY 4.0 licence.

You can find data by site, ecoregion or participant. You can also browse sites and audio recordings without signing in by selecting an option below. To participate in the analysis work you will need to log in or register for a new account on the A2O data portal.
