MUSIC INFORMATION RETRIEVAL BASED DATA INFRASTRUCTURE FOR ETHNOGRAPHIC SOUND RECORDINGS ARCHIVES

基于汉堡大学音乐学研究所过去十年的原创性研究，将开发一个基于内容的数字化历史民族志记录数据库基础设施方案，该方案围绕数据提取功能，采用信号处理操作员，由专业的语言学指导。因此，提出的项目解决了音乐学、系统音乐学和民族音乐学的核心要求，即以上下文和语义集成的方式提供对数字音频数据的大型储存库的计算机化访问，以允许通过采用直接从音频信号导出的公共且一致的参数集来对给定数据库内以及类似数据库之间的音频数据进行结论性校对。这是一项基础性研究，在涉及音乐和声音记录的保存和科学研究的广泛应用中有许多实际实施的可能性，在对该研究所拥有的大量历史人种学记录的数字副本进行系统分类的过程中，将进一步实施这一基于MIR的分类方案。一个专门的数字数据库-汉堡大学人种学录音档案馆（ESRA）目前正在收集这些数据，从而为实际执行本项目的主要要求提供了一个理想的开发和测试环境。这些档案尤其具有特殊的道德和伦理责任：它们构成了世界的音乐记忆。在全球文化变迁的影响下，许多口头传播的音乐传统正在迅速消失，另一些则早已灭绝;它们所留下的只是隐藏在民族音乐学档案书架上的历史记录。对科学界来说，一项紧迫的任务是以数字方式保存，并提供足够的机会，至少是这些曾经是生活的音乐文化的微弱痕迹，以免它们随着原始记录媒体的物理解体而被遗忘，永远消失。

Based on original research performed over the course of the past decade at the Institute of Musicology, University of Hamburg, a content-based database infrastructure scheme for digitized historic ethnographic recordings is to be developed, build around data extraction functions employing signal processing operators guided by specialized heuristics.The project proposed thus addresses a central requirement of Music Archiving, Systematic Musicology, and Ethnomusicology, namely providing computerized access to large repositories of digital audio data in a contextually and semantically integrated way to allow for conclusive collation of audio data within a given database, as well as between similar databases, by employing a common and consistent set of parameters derived directly from the audio signal. This constitutes foundational research with numerous possibilities for practical implementation in a wide range of applications dealing with the preservation and the scientific study of recorded music and sound.This MIR-based classification scheme is further to be implemented in the process of systematic categorization of digital copies of the extensive collection of historic ethnographic recordings in the institute's possession. A dedicated digital database, the University of Hamburg Ethnographic Sound Recordings Archive (ESRA) , is currently being populated with such data, thus providing an ideal development and testing environment for the practical implementation of the central claims of the project proposed herein.Besides the particular technical difficulties faced by archives of non-European music, as described below, these archives in particular carry an exceptional moral and ethical responsibility: they constitute the musical memory of the world. Many orally transmitted musical traditions are rapidly fading away under the influences of global cultural change, others have long become extinct; all that is left of them are the historic recordings hidden in the shelves of ethnomusicological archives. It is an urgent mandate to the scientific community to digitally preserve, and to provide adequate access to, at least these faint traces of what were once living musical cultures, lest they sink into oblivion as the original recording media physically disintegrate, becoming lost forever.
