The VisiSonics RealSpace 645 Audio-Visual Panoramic VRAP Camera captures high-resolution panoramic video and full-dimension audio in laboratory or field environments. Online and offline analysis and visualization tools enable sound source identification localization using, among other sources, sound pressure level dynamics. This report aims to extend the user manual produced by VisiSonics by familiarizing potential users of the VRAP with features, display elements, and procedures for operation of the VRAP hardware and software by using an illustrative use case where the VRAP was deployed in the field. The use case addresses limitations of the ecological frequency i.e., prevalence measure, an approach described by Ballas 1993 for determining the representativeness of a set of sounds in a given environment. The use case evaluates the impact of high-quality panoramic audiovisual captures of the environment on the observers ability to extract ecological frequency information from a scene.
