摘要： A sound signal switchover means capable of preventing pop noise sound in an audio system from being generated is down-sized, and a time constant of a time constant unit for the changeover of the sound signals can be varied, thereby enabling the switchover to be implemented with greater smoothness. A sound signal selection means (12) having a plurality of switches (SW 1a′ to SW 2b′) for switching over the sound signal to the sound signal having the different output level is provided between a sound input source, and a sound output means. When switching over the sound signal to the sound signal having the different output level, the sound signals before and after the switchover coexist and the switchover is implemented at that point in time. A time constant unit (8) is made up of a SCF built in an IC, and the time constant τ can be controlled to be freely adjusted by a clock signal Fclk obtained by dividing a reference signal generated in a VCO (6) by a variable frequency dividing rate.
