基于MATLAB的多声道动声效果研究

The Research of Running-sound Effect of Multi-track System Based on MATLAB

随着3D视频技术的出现及流行,观众在欣赏3D视频的同时对声音效果也有了更高的要求。在现有多声道音频标准下,研究了基于一个高保真的声音文件,通过MATLAB对其进行读取和高斯函数处理,再将处理后的数据输出为新的声音文件,并进行分割,送到各个声道播放。通过仿真及现场听者测试,使听者的听觉感受犹如身临其境的动声效果。

With the emergence and development of 3D video technology,audiences have higher expectations to the sound effect when watching the 3D video.Under the existing audio standard of the multi-track,this paper researches a hi-fi audio file.The file is read and disposed by Gaussian function in MATLAB.After disposed,the data of the file is saved as a new audio file,and then this audio file is divided into several parts and each part is saved as an audio file.Then each audio file is sent to a track to play.By simulation and test,the effect makes the audience as if they are in the scene.
