Bob Capranica was a towering figure in the field of auditory neuroethology. Among his many contributions are the exploitation of the anuran auditory system as a general vertebrate model for studying communication, the introduction of a signal processing approach for quantifying sender–receiver dynamics, and the concept of the matched filter for efficient neural processing of complex vocal signals. In this paper, meant to honor Bob on his election to Fellow of the International Society for Neuroethology, I provide a description and analysis of some of his most important research, and I highlight how the concepts and data he contributed still inspire neuroethology today.
