号処理装置。 ゛In an audio signal processing device that alternately writes audio signals into a pair of memories at a constant cycle and alternately reads audio signals from the pair of memories at a constant cycle, a read clock is generated to obtain a read clock of a desired frequency. means, first and second read counters to which the read clock is supplied, synchronous distribution means, and amplitude control means for controlling the amplitude of a plurality of outputs of the synchronous distribution means, ' The counter starts reading from the beginning of the fixed period, and the second reading counter starts operating based on the first reading counter, and completes reading from the memory at the end of the fixed period. , the synchronous distributing means synchronously distributes the first read signal read by the first read counter and the second read signal read by the second read counter, and the amplitude control means synchronously distributes the first read signal read by the first read counter and the second read signal read by the second read counter. An audio signal processing device characterized in that the amplitude of the first read signal is gradually decreased and the amplitude of the second read signal is gradually increased during a period in which the second read signal coexists.゛
