Sound Analysis Workshop

Bioacoustics Research Program


Sound Analysis Workshop Banner 

The Bioacoustics Research Program at the Cornell Lab of Ornithology offers a five-day 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. The workshop covers basic principles of spectrographic analysis and measurement of animal sounds, as well as specific tools and techniquesin Raven Pro, a sound analysis application program developed by BRP. 

The next workshop will take place in the fall of 2017. The dates have not been chosen yet, but if you'd be interested in attending, please contact Liz Rowland,

Since its inception in 2007, more than 200 participants from 32 countries have taken the class, 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 excellent opportunity to exchange ideas with fellow participants on your sound analysis research and to develop new contacts with staff and researchers in the Bioacoustics Research Program.

Workshop content and format

The first three days of the workshop consist mainly of lectures, demos, discussions, and hands-on exercises covering general principles andspecific techniques in Raven Pro. In the last two days we focus on review and follow-up of this core material and on specific needs and interests of the participants, in both small-group and individualized consultation sessions. Limiting the class size to 11 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.

Registration and logistics

The course is presented at the Imogene Powers Johnson Center for Birds and Biodiversity, home of the Cornell Lab of Ornithology, in Ithaca, New York.

The standard fee for the course is $1,400, but students enrolled in a degree program are eligible for the discount rate of $1,050. A deposit of $300 is required to reserve a place. The fee includes tuition, course materials, lunch for five 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."
