Abstract
An audio signal processing circuit for demodulating an audio multiplexed signal and outputting the demodulated signal extracts a second audio signal from the audio multiplexed signal, has plural amplifying units for amplifying the second audio signal with different gains, respectively, and selects one of the plural amplifying units, and the selected amplifying units selectively outputs an amplified audio signal.
