| Abstract(in English) | In multiplex sound analysis, it is generally difficult to recognize the pitch of each sound and the instrument category which belongs. In the conventional system, the sound quantity belonging to the same musical instrument category assumes that it has the same spectrum power ratio (harmonic structure), and analyzes using a fixed harmonic structure. However, harmonic structure is, in general, not constant. In this paper, harmonic structure is variably made by learning instrument sound in advance and making a model by a gauss process regression. And sound quantity to recognize and the category which belongs are specified by finding the optimal combination from this spectrum basis. We show the validity of the proposed system by measuring its recognition accuracy and the system which assumes the case of harmonic structure regularity. |
