1. An audio reproducing apparatus comprising:

  • audio decoding means for decoding an input audio signal frame by frame;

    data expanding/compressing means for subjecting data in a decoded frame to time-scale modification process;

    a frame sequence table which contains a sequence determined according to a given speed rate in which respective frames are to be expanded/compressed;

    frame counting means for counting the number of frames of the input audio signal; and

    data expansion/compression control means for instructing the data expanding/compressing means to subject the frame to one of time-scale compression process, time-scale expansion process, and process without time-scale modification process, with reference to the frame sequence table based on a count value output from the frame counting means, the data expanding/compressing means subjecting the audio signal to time-scale modification process in accordance with an instruction signal from the data expansion/compression control means.
