摘要

A method for measuring the similarity between the beat spectra of two or more audio works. A distance formula is used to measure the similarity by rhythm and tempo between shortened beat spectra B1(L) and B2(L). The result is a vector which measures the similarity of rhythm and tempo. A distance formula is used to measure the rhythmic similarity between the scaled beat spectra B1(L) and B2(L). The result is a measure of rhythmically similar music regardless of the tempo. 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.
