A program was developed to extract the fundamental frequencies from Korean traditional music. It calculates the short time frequency spectrum using a STFT and finds the approximate fundamental frequency using the SHS method. Then, it finally extracts the fundamental frequency of a tone accurately using an iterative method. It is shown that the program extracts the accurate fundamental frequencies from vibratos as well as from stationary tones.
