Resumo: Vocalizations with an emphasized fundamental are common in many species of animals. Such calls can presumably be sufficiently described by measures of their fundamental shape or 'contour'. Here we describe a software we developed to analyze such vocalizations semi-automatically. The software is particularly designed to cope with vocalizations recorded in a noisy environment. Some of the algorithms implemented (e.g. signal detection, contour detection, contour measurement, validation) and some preliminary applications dealing with calls of different species of birds are presented. Finally, we briefly discuss the possible significance of such vocalizations.
