<P>PROBLEM TO BE SOLVED: To achieve a voice signal converter, making voice easy to listen to and heightening the feeling of being there. <P>SOLUTION: The voice signal converter 1 converts a right voice signal corresponding to a right channel and a left voice signal corresponding to a left channel to a central normal voice output signal corresponding to a center channel, a right voice output signal corresponding to the right channel and a left voice output signal corresponding to the left channel. A common component extracting part 3 extracts a common component contained in common in the right voice signal and the left voice signal, and an inverter part 5 generates the central voice output signal from the common component. A multiplication part 4 decreases a component calculated by subtracting the common component from the right voice signal and the left voice signal, respectively, and the inverter part 5 generates time signals of the right voice output signal and the left voice output signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
