METHOD OF COMPARING AT LEAST TWO AUDIO WORKS, PROGRAM FOR REALIZING THE METHOD ON COMPUTER, AND METHOD OF DETERMINING BEAT SPECTRUM OF AUDIO WORK

摘要

PPROBLEM TO BE SOLVED: To provide a method of measuring the similarity between beat spectra of at least two audio works. PSOLUTION: A distance formula is used to measure the similarity by rhythm and tempo between shortened beat spectra, and as a result, a vector which measures the similarity of rhythm and tempo is obtained. A distance formula is used to measure the rhythmic similarity between scaled beat spectra, and as a result, a measure of rhythmically similar music regardless of the tempo is obtained. The method can be used in a wide variety of applications including concatenating music with similar tempos, automatic music sequencing, classification of music into genres, search for music with similar rhythmic structures, search for music with similar rhythmic and tempo structures, and ranking music according to a similarity measure.
