Abstract:
A method for calculating a similarity of audio files includes constituting a pitch sequence of a first audio file and a pitch sequence of a second audio file; calculating an eigenvector of the first audio file according to the pitch sequence of the first audio file, and calculating an eigenvector of the second audio file according to the pitch sequence of the second audio file; calculating a similarity between the first audio file and the second audio file according to the eigenvector of the first audio file and the eigenvector of the second audio file.
