APPARATUS FOR DISCRIMINATING AN UN-IDENTIFIED SIGNAL USING A REFERENCE MODEL AND METHOD THEROF

摘要

An apparatus and a method for discriminating an unidentified signal using a reference model are provided to analyze characteristic parameters at every time regions and thus to discriminate a sound/music signal in real time. A method of discriminating an unidentified signal using a reference model includes the steps of converting the unidentified sound/music signal into a frequency/time region(S501), extracting characteristic parameters from the unidentified sound/music signal in the frequency/time region(S502), comparing the extracted characteristic parameters with a reference model and discriminating the kind of the unidentified sound/music signal(S503), providing information on the reference model, converting the unidentified sound/music signal into the frequency/time region(S506), and extracting characteristic parameters from the sound/music signal.
