Abstract

PURPOSE:To achieve the effect of sound field extension, by forming indirect tone signal suitable for monaural signal and stereo signal, by supplying the indirect tone signal to separate delay element and outputting it with the stereo control signal selection. CONSTITUTION:The indirect tone synthesis circuit 1 outputs the L-R signal at stereo signal after synthesis and outputs either one of left or right signal at monaural signal. On the other hand, two delay elements for stereo and monaural are separately located as the delay element 9, they are driven with separate clock signal from the clock oscillation circuit 10 to output the delay signal for monaural and stereo separately, selection is made with the stereo control signal ST at the indirect tone switching circuit 11, and the signal selected at the indirect tone switch circuit 5 is controlled with the switch input signal SW, double broadcast control signal MP and main and sub-control signal MS whether or not the signal selected at the indirect tone switch circuit 5 is transmitted to the post stage.
