摘要
提出了一种基于头相关传输函数的三维空间环绕声的耳机重放方法。该方法打破了以往耳机重放多声道音频系统中采用二维信号馈给的方式,通过使用具有一定仰角的HRTF数据,给音频信号加入竖直方向的听音效果,使得听者感觉到更加强烈的立体感。非正式主观测试结果表明,与二维信号馈给方式相比,所提出的虚拟三维空间环绕声系统具有更好的立体感。
A virtual three-dimensional sound reproducing method is proposed in this paper. Based on HRTF （ Head-Related Transfer Function）, this paper introduced a novel three-dimensional sound location method. In this method, non-zero elevation HRTF data＇ are chosen to add the third dimension effect, which makes the sound more stereo. Informal subjective testing results show that, comparing to the two-dimensional method, the proposed three-dimensional method has a better stereo effect.
