1. A method for automatically classifying melodic movement properties of audio data, comprising:

  • applying audio data to a peak detection process;

    detecting the location of at least one prominent peak represented by the audio data in a frequency spectrum and determining the energy of the at least one prominent peak;

    storing the location of the at least one prominent peak and the energy of the at least one prominent peak into at least one output matrix;

    applying data stored in said at least one output matrix to critical band masking filtering;

    applying data stored in said at least one output matrix to a peak continuation process; and

    applying data stored in said at least one output matrix to a melodic movement vector calculation process that determines pitch class movement data corresponding to the audio data for the melodic movement vector.
