Computerized auditory scene analysis particularly suited for undersea applications

A digital signal processor is disclosed for analyzing sound signals to determine the identification of the sound and the location of the source of the sound, as well as to present its results as an auditory scene. The processing includes producing a gram representative of a sound signal in time, frequency, and space parameters, and then extracting elements from the gram and features from the elements. The elements and the features are routed to an inference engine, which also receives predefined knowledge from a database. The inference engine derives conclusions, which are used to produce the auditory scene.
