Claim 16:
17. The method of claim 16, wherein performing the smoothing processing on the current audio variable-speed data to obtain the smooth audio variable-speed data comprises:
determining a starting position of a signal segment to be smoothed in the current audio variable-speed data and an ending position of the signal segment to be smoothed in the current audio variable-speed data;
determining, according to a set quartic function calculation formula, a target signal strength value and a first derivative of the starting position and a target signal strength value and a first derivative of the ending position; and
forming a smooth curve based on the target signal strength value and the first derivative of the starting position and the target signal strength value and the first derivative of the ending position, and using the smooth curve to replace the signal segment to be smoothed to obtain the smooth audio variable-speed data of the current audio variable-speed data.
