Raven is a software program for the acquisition, visualization, measurement, and analysis of sounds.
Raven Pro provides a powerful, user-friendly research and teaching tool for scientists working with acoustic signals. Raven Pro's highly configurable views provide unparalleled flexibility in data display. Student discounts and per country discounts are available.
Raven Exhibit is a sound visualization and recording system optimized for public displays and exhibits in places like science museums, zoos, aquariums, and nature centers.
Raven Lite is a free software program that lets users record, save, and visualize sounds as spectrograms and waveforms. Raven Lite is intended for students, educators, and hobbyists, and can be used for learning about sounds, as an aid in birdsong recognition, and in musical instruction.
Raven on 4K Monitors
Windows users with a 4K monitor may want to install Java 9, which provides for more optimal scaling of fonts and toolbars in Raven. Java 8 is still recommended for Mac OSX systems and Windows systems that don't have 4K monitors.
For more information, see Windows Info for Raven.
The Cornell Bioacoustics Research Program is pleased to announce the release of a series of short video tutorials introducing the most widely used features of Raven Pro 1.5 bioacoustic analysis software.
Although these tutorials "begin at the beginning," experienced users may learn something as well.
Presently the videos are available in English only, but we plan to produce versions in other languages as well.
Raven Lite users may find these videos helpful as well.
We are pleased to announce the SWIFT, our new terrestrial autonomous recording unit.
Our hope is that this unit will enable not only researchers, but also hobbyists, from all over the world to collect acoustics data in support of wildlife conservation efforts.
Order Raven Lite 2.0 free of charge from the Cornell Lab of Ornithology E-Store.
Thanks to Lisa Yang, Sylvia Gallagher, and other generous donors for making this free version possible.

The Bioacoustics Research Program offers a five-day introductory-level Sound Analysis Workshop featuring Raven Pro twice each year.
The workshop is intended primarily for biologists interested in analysis, visualization, and measurement of animal sounds. The workshop covers basic principles of spectrographic analysis and measurement of animal sounds, as well as specific tools and techniques in Raven Pro, a sound analysis application program developed by BRP.
For details, see Sound Analysis Workshop.
