About
Raven Pro is a professional-grade sound analysis software suite built by the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology. Designed for bioacousticians, wildlife researchers, and environmental scientists, Raven Pro enables detailed acoustic analysis through an intuitive multi-window interface that displays waveforms, spectrograms, and cepstrograms simultaneously. The software excels at visualizing and measuring sound features—including frequency, duration, amplitude, and bandwidth—allowing researchers to annotate, classify, and compare vocalizations from birds, mammals, insects, and other sound-producing organisms. Selection tables streamline the annotation workflow, making it easy to catalog large volumes of recordings from passive acoustic monitoring deployments. Raven Pro supports batch processing and a range of audio file formats, making it suitable for both in-lab analysis and post-field data processing. Its measurement tools are highly configurable, enabling precise extraction of acoustic parameters for scientific publication. The software is also widely used in educational settings, with Cornell offering virtual lab training and video tutorials. Raven Pro is the professional tier offering in a family that includes the free Raven Lite and the newer cloud-oriented Raven Workbench. It is an industry standard in passive acoustic monitoring and bioacoustics research, trusted by institutions and independent researchers worldwide.
Key Features

- Broad File Format Support: Import and work with a wide variety of audio file formats commonly used in field recording and bioacoustics research.
Use Cases
- Analyzing bird vocalizations and song structure for ornithological research and species identification.
- Processing long-duration passive acoustic monitoring recordings to detect and log wildlife sound events.
- Annotating and measuring acoustic parameters for peer-reviewed bioacoustics publications.
- Teaching students the principles of sound analysis and acoustic ecology in university or virtual lab settings.
- Monitoring soundscapes for conservation assessments and biodiversity surveys in ecologically sensitive areas.
Pros
- Industry-Standard for Bioacoustics: Developed and maintained by the Cornell Lab of Ornithology, Raven Pro is trusted worldwide as the benchmark tool for acoustic ecology and wildlife sound analysis.
- Comprehensive Visualization: The multi-window interface provides simultaneous views of sound data, enabling nuanced analysis not possible with simpler tools.
- Strong Educational Resources: Backed by Cornell's virtual labs, video tutorials, and knowledge base, users at all experience levels can get up to speed quickly.
Cons
- Paid License Required: Raven Pro requires a purchased license, which may be a barrier for individual researchers or institutions with limited budgets (a free Lite version exists but lacks advanced features).
- Desktop-Only Application: Raven Pro runs only on desktop operating systems and is not available as a web or mobile app, limiting remote or collaborative workflows.
- Steep Learning Curve for Beginners: The depth of features and scientific terminology can be overwhelming for users who are new to acoustics or bioacoustics research.
Frequently Asked Questions
