QBH System Using Melody Matching Model based on a String Pattern Matching mechanism of Frequency Contours

By D. K. Withanage


Abstract — Query by humming (QBH) refers to music information retrieval systems where short audio clips of singing or humming act as queries. Melody is considered as the most important feature in the queries and the songs. This system proposes a QBH system Using Melody Matching Model Based on a string pattern matching mechanism of frequency contours, which is used to align the input pitch frequency contour with the original music pitch frequency contour. The proposing comparison algorithm provides about of 60 % of accuracy which is comparatively good considering the accuracy level of existing QBH systems
