摘要
结合音频检索发展现状,描述了当前相关研究的进展,介绍了现在最常用到的音频检索方法,讨论了与音频检索相关的关键技术:音频特征提取、音频分割和分类。基于内容的音乐检索研究是一种涉及音乐理论、信号处理、模式识别等相关领域的综合学科研究,其在音乐数据库管理I、nternet音乐检索以及生活娱乐等方面都具有非常重要的意义。分析并总结出音乐内容及其检索的概念,给出音乐检索的系统结构,综述了基于内容的音乐检索方法,最后指出了音频检索发展的前景。
Traditional simple method of retrieval is no longer adequate for multimedia data, since the digitized representation of images, video, or data do not convey the reality of these mediaitems. The research of contentbased musical retrieval is composed of the study of musical theoretics, signal processing and pattem recognition. And it is significant for the management of the music digital library, the music search in the Intemet and the daily amusement. Therefore, contentbased retrieval for audio data is realized taking such intrinsic features of multimedia data into account. Surveys recent studies on content- based retrieval for music databases from the point of view of some fundamental issues.
