Sound Analysis Workshop

BRP Sounds Analysis Workshop

The Bioacoustics Research Program at the Cornell Lab of Ornithology offers a week-long introductory-level Sound Analysis Workshop, usually twice per year. The workshop is intended primarily for biologists interested in analysis, visualization, and measurement of animal sounds. We cover 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. Spring workshops also include a brief introduction to techniques for targeted field recording using directional microphones.


Next workshop: Fall 2019 (Dates: TBD) 

Since its inception in 2007, over 400 participants from 43 countries have participated in the workshop, with basic and applied research interests in the sounds of birds, marine mammals, bats and other terrestrial mammals, frogs, insects, and fish.

The workshop provides an opportunity to exchange ideas with fellow participants on your sound analysis work and to develop new contacts with staff and researchers in the Bioacoustics Research Program.

 Workshop Content and Format

Workshop content is presented in the form of lectures, demos, discussions, and hands-on exercises covering general principles and specific techniques in Raven Pro. Spring workshops include early two early morning field recording practice sessions. In the last two days of the workshop we focus on review and follow-up of core material and on specific needs and interests of the participants, in both small-group and individualized consultation sessions. Limiting the class size to 12 participants allows us to give attention to each individual’s needs. Throughout the week, guest presentations by Cornell and visiting researchers illustrate diverse applications of analysis principles and techniques discussed in the workshop.

Is this Workshop Right for You?

In a one-week workshop, there is not enough time to cover everything that participants might need to know in order to use bioacoustic principles and methods in their work. Instead, our goal is to provide a basic foundation of concepts and tools, upon which participants can continue to build after the workshop ends.

The following two documents should help you determine whether this workshop would be worthwhile for you, given your specific interests and needs.

The standard fee for the workshop is approximately $1,430, but students enrolled in a degree program are eligible for the discount rate of $1,080. A deposit of $300 is required to reserve a place. The fee includes tuition, course materials, lunch for six days, a one-year license for Raven Pro and a hard copy of the Raven Pro User’s Manual. (Students may renew the Raven license for as long as they remain students.) Participants are responsible for their transportation, accommodation, and meals other than lunch. A range of accommodations is available nearby.

Workshop registration is open to anyone. However, we ask that potential participants first complete a brief online questionnaire about interests and background, in order to ensure a good match between workshop content and participant interests..

Participants are expected to provide their own Windows or Mac laptop.

About Automated Species Identification

Some people who consider attending the Sound Analysis Workshop hope to learn about the use of software to automatically find and identify sounds made by multiple species in audio recordings. Raven Pro cannot automatically identify animal species by their sounds. Although fully automated acoustic species identification is an active area of research and development, we are not aware of any software that performs this task reliably under a wide range of conditions. The Sound Analysis Workshop does include discussion of Raven Pro’s band-limited energy detector (BLED). The BLED can find generic acoustic events of specified durations in a specified frequency band. Depending on the recording, the sounds found may be from multiple sources in addition to an intended “target.”
