3D沉浸式音乐录音传声器阵列技术发展综述

Review on the Development of 3D Immersive Microphone Arrays Technology for Music Recording

随着视听技术的发展进步,音频技术从最初的单声道技术发展到现在的3D沉浸式音频技术。3D沉浸式音频是一种划时代的音响创作新趋势,它可以拓宽音乐创作思路,丰富音乐的表现力,让听众实现身临其境的沉浸式体验。3D沉浸式音频初期主要应用于影视领域,后来逐步拓展到音乐、游戏及互联网视频等新领域。近年来,国内外提出了许多用于3D沉浸式音乐录音的传声器阵列技术,为了根据录制内容选择最合适的录制方式,必须了解不同传声器阵列的设计原则以及优缺点等。本文根据传声器的配置、设计理念及用途,对现有几种常见的3D沉浸式传声器阵列进行分类,并对不同传声器阵列的国内外研究成果进行综述,为创建身临其境的听觉体验提供理论和实践上的见解,总结以往研究的局限性和未来3D沉浸式录音方面的研究课题。

With the development and progress of audio-visual technology, audio technology has developed from the original single track to the 3D immersive audio technology nowadays. 3D immersive audio is an epoch-making new trend of sound creation, which can broaden the ideas of music creation, enrich the expressive force of music, and enable the audience to achieve immersive experience.3D immersive audio was mainly applied in the field of film and television at the beginning, and gradually expanded to new fields such as music, games and Internet video. In recent years, many microphone array technologies for 3D immersive music recording have been proposed from domestic and overseas. How to choose the most appropriate recording method according to the recording content, so it is necessary to understand the design principles, advantages and disadvantages of different microphone arrays. This paper based on the configuration, design idea and purpose field of microphone, to classify several common 3D immersive microphone arrays, and review on several research results of microphone arrays at home and abroad, to create immersive audio experience provide insights on the theory and practice, summed up the limitations of previous research and the future research subjects on 3D immersive sound recording.
