ABSTRACT:
An audio signal reproduction apparatus for reproducing scratch sound from an optical disk. Scratch reproduction operation is performed through use of a jog dial and a turntable. When either the jog dial or the turn table has been actuated, a rotational operation signal of the thus-actuated element is supplied to a main system controller of the apparatus. The main system controller detects a rotational direction and a rotational speed, which have been achieved at the time of scratching operation, on the basis of the rotational operation signal, thereby controlling reading of audio data from memory. The main system controller processes the rotational operation signal in accordance with a jog dial/turntable switching signal, thereby controlling reading of audio data such that the same scratching sound is output when the same rotational operation has been performed.
