| 中文摘要: |
| 自上世纪30年代引入立体声以来,人类对逼真的听觉体验一直进行着孜孜不倦的追求。双耳音频处理技术基于人耳听觉感知特性,利用计算机和数字信号处理等技术在听者双耳鼓膜处模拟出与真实场景相同的声压,以期给人以“身临其境”的体验,一直是音频信号处理中的重要研究内容,特别是近两年随着虚拟现实等应用的蓬勃发展,得到更多关注。本文主要围绕双耳音频处理技术中所涉及的主要关键环节：双耳录音、双耳合成、耳机重放、扬声器重放、头跟踪等领域,以及相关典型应用场景进行较为系统介绍,最后给出总结和展望。 |
| 英文摘要: |
| Since the introduction of stereophonic sound in the 30s of last century, human beings have been pursuing more authentic auditory experience. Binaural technology tries to simulate the same sound pressure at listener’s eardrums as that in a real sound scene by using the signal processing techniques, which is expected to offer listener an immersed sense. It has been an important research topic in the field of audio signal processing, especially in the last two years with the boom of virtual reality. This paper mainly focuses on the key issues in binaural technology: binaural recording, binaural synthesis, headphone-based binaural audio playback, loudspeaker-based binaural audio playback, head movement tracking and the associated typical applications. Finally, the summary and prospect are outlined. |
