<P>PROBLEM TO BE SOLVED: To provide a sound circuit capable of improving the stereophonic sense. <P>SOLUTION: The sound circuit is provided with two stereophonic microphones; two gain variable amplifiers each provided on each microphone and for amplifying output signals from the microphones; and a gain control means for controlling the gain of the two gain variable amplifiers; and the gain control means controls both the gain variable amplifiers so as to increase the gain of the gain variable amplifier corresponding to the microphone, whose output signal level is higher and to decrease the gain of the gain variable amplifier corresponding to the microphone whose output signal level is lower. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
