    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.

    Abstract translation: 音乐信息搜索方法包括从音频数据中提取调制频谱,通过使用与所提取的调制频谱相关的预设峰值点的位置信息产生调制频谱峰值音频指纹,将生成的调制频谱峰值点音频指纹转换为指示 通过哈希函数存储在散列表上的哈希表和哈希值的地址,以及通过提取与音频查询剪辑相关的散列键并将提取的散列键与所指示的哈希表的地址进行比较来搜索音乐信息。
