ABSTRACT:
In a method of reproducing audio signals of the present invention, audio reproducing speed can be changed without changing tone and quality of audio signals. Audio signals are filtered to extract basic audio signals. Zero-cross points in the basic audio signals are detected. The original audio signals are divided into a plurality of frames on the basis of the zero-cross points on a time axis. The frames are thinned out, and the original audio signals are reproduced as voice on the basis of the frames left so as to accelerate reproducing speed. On the other hand, the original audio signals are reproduced by repeating the frame so as to make reproducing speed slower.
