The Bioacoustics Research Program at Cornell University has made the first alpha build of Raven Pro 1.5 available on our web site, http://RavenSoundSoftware.com. Raven was created to help scientists acquire, visualize, measure, and analyze sounds. The availability of version 1.5 comes at the 10th anniversary of the first beta release of Raven 1.0. Version 1.5 is the 9th version of Raven to be released and includes a gridded selection review and annotation tool that should be useful for rapid review and human classification of selections created by detectors or manual human browsing. It also includes support for real clock times in the time axis, new playback features, and the ability to compare selection tables to assess detector performance. Available in an upcoming build is an auto-save feature in the selection table. One-time 30-day trial licenses of Raven Pro 1.4, which can be used with version 1.5, are available by writing to raven_orders@cornell.edu. For more information on the software, including a history of the product since its first beta release on October 31, 2002, please visit our web site, http://RavenSoundSoftware.com. We hope that users on this listserve will take advantage of this opportunity to try out the new version of the software.
