| 内容記述 | A sound field reproduction method which uses blind source separation and head-related transfer function is proposed. In the proposed system, multichannel acoustic signals captured at the distant microphones are encoded to a set of location/signal pairs of virtual sound sources based on frequency-domain ICA. After estimating the locations and the signals of the virtual sources, by convolving the controlled acoustic transfer functions with each signal, the spatial sound at the selected point is constructed. In the evaluation, the sound field made by 6 sound sources is captured using 48 distant microphones and is encoded into set of virtual sound sources. Subjective evaluation shows that there is no significant difference between natural and reconstructed sound when more than 6 virtual sources are used. Therefore the effectiveness of the encoding algorithm as well as the virtual source representation is confirmed. | |||||
