| Abstract(in English) | In general, the farther the distance between the microphone and the sound source, the greater the spatial propagation spread of the sound source signal. However, in an actual sound field, the degree of spatial propagation spread cannot be determined in advance because it depends on the operating environment, such as room volume, wall material, sound source location, and a kind of sound source. Therefore, it is desirable to use a sound source separation method that is adaptable to such a situation. In this study, an adaptive filter is applied to the sound source separation signals based on complex weighted sum circuits to deal with spatial propagation spreading. Several experimental results in real room environments are shown to present the effectiveness of the proposed method. |
