Embodiment Construction

[0033]Certain exemplary embodiments of the inventive concept will now be described in more detail with reference to the accompanying drawings.

[0034] In the following description, the same drawing reference numerals are used for the same elements even in different drawings. Matters defined in the description, such as detailed structures and elements, are provided to help a comprehensive understanding of the inventive concept. Therefore, it is apparent that exemplary embodiments of the inventive concept can be carried out without those expressly defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the disclosure with unnecessary detail.

[0035] figure 1 is a block diagram of a music information search device according to an exemplary embodiment.

[0036] refer to figure 1 , the music information search device 100 includes a modulation spectrum audio fingerprint generator 110 and an audio data searcher 120 .

Abstract

A music information searching method includes extracting modulating spectrums from audio data, generating modulating spectrum peak point audio fingerprints by using position information which relates to preset peak points from the extracted modulating spectrums, converting the generated modulating spectrum peak point audio fingerprints into hash keys which indicate addresses of hash tables and hash values that are stored on the hash tables via hash functions, and searching music information by extracting hash keys which relate to audio query clips and comparing the extracted hash keys with the indicated addresses of the hash tables.

Description

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 725,666, filed November 13, 2012, with the United States Patent and Trademark Office and 10-2013-, filed July 12, 2012, with the Korean Intellectual Property Office Priority of Korean Patent Application No. 0082245, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Methods and devices consistent with the disclosure herein relate to a music information search method and device thereof, and more particularly, to a music information search method using modulation spectrum and device thereof. Background technique [0003] Existing music information search methods extract features for searching audio by using a power spectrum generated as a result of converting an audio signal into a frequency domain using Fast Fourier Transform (FFT). Therefore, a problem occurs because such a method is not robust against various noise environments. [000...
