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.
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.
