| Abstract(in English) | We have previously proposed a processing model OPTIMA for music scene analysis and implemented its experimental system. However, the system was not robust to signals with overlapped frequency components. In this paper, we present a new method that improves this problem by using overlap pattern of frequency components. Weighted template-matching method is applied to identify sound sources repeatedly to each frequency component cluster. The weight is evaluated according to the significance of each feature of the signal. When multiple components are overlapped, our system adaptively modifies features of an input signal to a combination of overlapped components. The experimental results show that the system can identify sound sources of 60 to 69% of musical notes. It also showed improvement the accuracy about 5%, compared to the result without the proposed mechanism. |
