In particular, we use this modified apparatus in relation to the problem of the instrument intonation, i.e., how to obtain correctly tuned notes on these string instruments. The experimental procedures presented in this study can become a more structured laboratory activity to be used in general physics courses or acoustics classes.展开更多
近20年来,音频压缩技术的成熟及互联网的普及使得音乐迅速从磁带和激光唱盘(CD)转变为互联网上以MP3为代表的数字音乐.海量数字音乐带来分类组织、查询检索、内容理解与分析等一系列问题,促使产生了一个新兴的交叉学科,即基于内容的音...近20年来,音频压缩技术的成熟及互联网的普及使得音乐迅速从磁带和激光唱盘(CD)转变为互联网上以MP3为代表的数字音乐.海量数字音乐带来分类组织、查询检索、内容理解与分析等一系列问题,促使产生了一个新兴的交叉学科,即基于内容的音乐信息检索(Content-based Music Information Retrieval,MIR).本文阐述了MIR与音乐科技、声音与音乐计算、计算机听觉、语音信息处理、音乐声学等各个相关领域概念的区别与联系,将MIR技术的数十个研究领域按照与音乐要素的密切程度划分为核心层与应用层.分类总结了各领域的概念、原理、应用、基本技术框架及典型文献,同时介绍了研究中常用的音乐领域知识并明确了中英文术语.最后总结MIR领域存在的各方面问题,并展望其未来发展趋势.展开更多
