A method and a system for converting sampling rate targeting specific sampling rate are provided to perform sampling rate conversion for the frequency band unable to be accommodated for input sampling rate of conventional audio, by using an optimized conversion factor and coefficient value. According to a sampling rate conversion method, output sampling rate is determined by referring to input sampling rate. An intermediate frequency is calculated by using the input sampling rate and the output sampling rate. A plurality of conversion factors is derived from the relationship among the intermediate frequency, the input sampling rate and the output sampling rate. A coefficient value of a function used in sampling rate conversion is determined by using the derived conversion factors selectively. Sampling rate is converted by using the function.
