摘要：
Studies on query-by-humming (QBH) have recently become increasingly popular. On the basis of the fact that MP3 and MIDI formats have the advantages of small storage space and high audio quality, thereby making them suitable for Internet applications, we propose a novel approach based on QBH to retrieve information from MP3 and MIDI formats. In the database establishment phase, each music file is first partitioned into a set of musical data objects encoded via mapping function, including bi-gram, tri-gram and four-gram approaches, to establish a music database. In the retrieval phase, the file most similar to the musical test segment can be retrieved from the music database. Experiments were conducted to demonstrate the effectiveness of our approach.
