Abstract: PURPOSE: A sound source search system and a method combining matching algorithms based on a plurality of SVM searching humming are provided to combine DTW(Dynamic Time Warping), EMD(Earth Mover's Distance) and matching score obtained from LS(Linear Scaling) method thereby providing exact sound source search result. CONSTITUTION: An audio signal analyzer(120) analyzes audio signal and extracts feature value of the audio signal. An audio signal matching searcher](140) uses feature value of corrected audio signal and applies the first and the second matching algorithm and produces the first and the second output value. The audio signal matching searcher uses the first and the second output value as an input and produces similarity measured value and searches and extracts sound source having high similarity based on the produced similarity measured value from sound source data base.

Abstract: PURPOSE: A fast music information retrieval system and method based on query by humming are provided to eliminate unnecessary matching attempts to unnecessary matching regions, thereby increase speed of music source retrieval while maintaining accuracy of retrieval. CONSTITUTION: A database (100) stores music sources, and a processor (200) searches for a partial region of the stored music sources and an inputted humming to explore changes of pitch values. The processor extracts feature information related to the explored changes from the inputted humming and the music sources, and measures a distance between the inputted humming and the music sources based on the extracted feature information. If the distance is less than a threshold, the processor performs matching by dynamic time warping (DTW) with the inputted humming and pitch values extracted from the music sources.
