摘要
声景研究中常常需要对声音的原生环境进行音视频记录,以用于主观评价中的场景重现.沉浸式视听技术的发展可以使重放的场景从传统的二维平面向三维立体空间拓展,从而让人类得到更逼真的视听体验.为了研究不同沉浸式技术在记录声景内容方面的有效性,本文使用了 2种不同的方案采录了 4个点位的声景素材,并采用主观评价实验的方法对采录的数据进行研究分析.结果显示,全景视频+FOA音频的记录方案总体呈现出更好的视听表现.
Abstract
The subjective evaluation was one of the important methods of soundscape research,thus the audio-visual reproduction of soundscape was often required in research.The development of immersive audiovisual technologies makes it feasible to expand the reproduced scenes from the traditional 2-D plane to the 3-D space.To study the effectiveness of different immersive techniques in terms of recorded soundscape content,two different methods were used to record soundscape material in 4 scenes and the recorded data were analyzed using subjective evaluation experiments.The results showed that the methods using panoramic video and FOA audio presented a better overall audiovisual performance.
