Free Raven licenses

Raven Lite

Raven Lite licenses, previously priced at $25 each, are now free. Download the software from the Download page, then get a free license.

Demonstration Version

From this web site, you can download a demo version of Raven which lacks the ability to save files, and runs for only ten minutes at a time. To enable all features of Raven, you must purchase a license. Once you have purchased a license, you will receive an e-mail message containing a license code and instructions for transforming the demo version into a fully functional version. No further downloads will be needed for this purpose.

Trial Evaluation Licenses

If the demo version does not give you enough time to evaluate Raven, write to raven_orders@cornell.edu for a one-time, free 30-day trial license.

Instructors can request an evaluation license of Raven to use for six (6) months in their classrooms on a single computer to evaluate Raven's usefulness as an aid in teaching.

License Awards

In 2005, BRP awarded a small number of free licenses for Raven to researchers in the field of animal bioacoustics. These awards were intended to make Raven available to investigators for whom the standard $400 license fee would have been prohibitive, such as researchers in developing countries or graduate students without access to large research grants. Awards were intended for basic research on the functions, mechanisms, development, or evolution of animal acoustic communication systems, or for conservation-oriented applied research. Award decisions were made by a committee of BRP scientists and software developers on the basis of scientific merit and financial need.

For more information and to see the winners of the free licenses, click here. This awards program has been discontinued in favor of two newer programs, one that provides students with a 75% discount off the price of Raven Pro, and the second that provides country discounts for Raven users in many countries.


A discount of 100% off the price of Raven Pro is available to non-commercial users from over 100 countries based on Gross Domestic Product (GDP) per capita at Purchasing Power Parity (PPP), a metric used by the United Nations as part of its Human Development Index.

Students and postdocs can license Raven for $100 instead of $400. The license lasts for a year and can be renewed for free as long as the student or postdoc remains a student or postdoc. Click here for more information on student licenses.


Upgrades from any Raven (Pro) version to Raven Pro 1.4 and Raven Pro 1.5 are free. Download the new version of Raven Pro and reuse your existing serial number. There are no free upgrades from Raven Lite to Raven Pro.

Why aren't all versions of Raven free?

Funding for the initial release of Raven was provided by a grant from the National Science Foundation (NSF). The grant funded part of the initial development and stipulated that subsequent and on-going development be funded from sales of Raven. All stages have been supplemented from the budget of the Bioacoustics Research Program. Thanks for helping us to recover our initial investment and for supporting current Raven development.

For information on other software developed at the Bioacoustics Research Program, some of which is free, visit the BRP software site.
