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.

Sound Analysis Workshop

The Bioacoustics Research Program is offering a five-day introductory-level Sound Analysis Workshop featuring Raven Pro from Monday October 2 to Friday October 6, 2017 at the Cornell Lab of Ornithology in Ithaca, New York.

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.

Raven Pro 1.5


The Raven developers just released a major new update of Raven Pro 1.5, which includes two new features as well as a number of bug fixes and improvements. With this update, the "beta" designation has been officially removed, so we recommend that Raven Pro 1.4 users install Raven Pro 1.5 instead.

To get Raven Pro 1.5, you must re-install Raven Pro whether you have Raven Pro 1.5 beta or Raven Pro 1.4. The automatic update feature cannot do this. Please contact Raven Software Support if you have any question.
