Test of pitch extraction algorithms for query-by-singing/humming system

This paper presents the test results of the Query-by-singing/humming(QbSH) system, which are measured with varying the pitch extraction algorithm. The test is for verifying matching engine of our QbSH system of which database is constructed from polyphonic recordings such as MP3 files. For the test, we used 3 different pitch extraction algorithms, and the experimental results are obtained with our matching engine. From the results, we can conclude that our matching engine works well with any pitch extraction algorithm.
