Raven Software
Raven is a software program for the acquisition, visualization, measurement, and analysis of sounds. We offer several different packages:
Raven Workbench
Raven Workbench is a comprehensive suite of applications designed to enhance and replace the capabilities of Raven Pro, and support your audio analysis and passive acoustic monitoring (PAM) workflow. Our goal is to provide a set of modern software tools that are easier to use and focused on various steps in the PAM workflow.
Raven Annotate
For the creation, editing, and reviewing of a list of selections made from a sound file or a sequential array of sound files.
Raven Expedition
For the display and annotation of long-term spectrogram averages and which has an option to generate spectrograms using a hybrid-millidecade frequency scale.
Raven Intelligence
For applying machine learning models to audio data, enabling you to automate sound detection and classification and train new sound detector-classifiers.
Raven Compass
For the preparation of sound files for sound analysis, performing such tasks as changing audio file format, audio encoding, sample rate, bit depth, file name, etc. (replacing Sox-o-matic)
Why update?
Raven Pro has been in development for over 20 years. The methods and approach for analyzing acoustic data has changed over that time, and we need new tools that are easier to use, more flexible, and more modern to adapt to these changes.
By separating the features into smaller simple applications sharing a common core, we can be more flexible and responsive when adding new features.
Will Raven Workbench replace Raven Pro & Raven Lite?
Maintaining legacy software takes a lot of work. Eventually we will no longer sell or support Raven Pro, replacing it with the new Workbench apps.
Legacy downloads will still be available. We will release a version with updated license terms allowing free access to it after support ends.
Raven Pro
Raven Pro is 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 Pro is one of the most widely used programs worldwide for the analysis of animal sounds, used in more than 1000 peer-reviewed scientific publications. Check out our introductory video tutorials on how to use Raven Pro.
We distribute Raven Pro free of charge to:
- People from low and middle-income countries
- Native Americans, Native Alaskans, Native Hawaiians, First Nations, Pacific Islands, Australian Aboriginals, and other aboriginal people
- Members of the Cornell community, including alums and former employees
Raven Lite
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 Exhibit
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.
