Abstract
Through analyzing the humming melodies pitch extraction and retrieval algorithm, a complete system framework of Query By Humming(QBH)is proposed. It includes the melody feature extraction and approximate melody matching in MIDI music database. The Mel Frequency Cepstral Coefficients(MFCC)is extracted. Through analyzing the theory of DTW algorithm, the cosine similarity of the delta duration sequence is added with the characteristics of the sound for per-formance improvement of the system. Experiments are conducted in a test set of 340 MIDI songs. The system gets a success rate of top-3 increased by 3.7%and a 16%time reduction.关键词
