<P>PROBLEM TO BE SOLVED: To provide a low-pitched sound reproducing device for generating and outputting a low-pass component from each sound signal supplied from a plurality of sound signal input devices. <P>SOLUTION: Each input signal subjected to unique signal processing by each signal processor is input to a mixer (a mixer block) 4 of the next stage, respectively. The mixer 4 generates the low-pass component of the sound signal by mixing each of sound signal processing outputs subjected to the unique sound signal processing with a plurality of the sound signal processors, respectively. A plurality of the sound signal processing outputs supplied to the mixer 4 are already filtered in each signal processor, and the desired low-pass components are extracted from a plurality of the sound signal processing outputs. The mixer further generates the low-pass components on the basis of an adjustable mixture ratio. <P>COPYRIGHT: (C)2007,JPO&INPIT |
