Abstract:
A method of reproducing audio signals, comprising the steps of:reading a predetermined amount of original audio signals from a recording medium;filtering said original audio signals to extract basic audio signals;detecting zero-cross points in said basic audio signals;dividing said original audio signals into a plurality of frames, each having a starting point and a terminating point which corresponds to a detected zero-cross point on a time axis;thinning out said plurality of frames;monitoring the results of said detecting step to recognize no zero-cross point sections of said basic audio signals for which said detecting step fails to detect zero-cross points;reducing an amount of original audio signal data for portions of said original audio signals which correspond to no zero-cross point sections of said basic audio signals recognized by said monitoring step, the amount of reduction being based on a desired accelerated reproducing speed; andreproducing the original audio signals in accordance with the results of said thinning and reducing steps to accelerate reproducing speed.
