Summary:A method for controlling the speed of audio signals is provided. The method is based on a TSM that uses an optimized AMDF and an OLA. According to the method, the number of frame sets is differently set depending a TSM speed rate to set the interval of a speed rate, and the number of frame sets required for adjusting the speed rate is determined. Subsequently, a TSM process is performed only when the TSM process is required for the frame set determined to adjust the speed rate, and speed processing is performed such that an input frame becomes an output frame otherwise.
