The technology of music retrieval by humming and its application in internet music search system

摘要

This paper applied the technology of music retrieval by humming into music retrieval by humming, proposed a complete framework of humming retrieval. We has proposed a new energy-based note segmentation algorithm and a new approximate matching algorithm—similarity matching. Based on the note segmentation and pitch extraction, we use the characteristics of algorithms to achieve core functions of internet music search system. The author did experiments on the system of internet music search by humming, and got the result that the algorithms' comprehensive efficiency is superior, on the two standard of the query hit ratio and query speed. The framework, which we proposed, is applicable to the internet music search.
