| 摘 要： | 为改善5.1通路环绕声的双耳重放性能,提出一种基于低价头踪迹跟踪模块的动态双耳重放方法。头踪迹跟踪模块通过单片机采集磁传感器、加速度传感器的输出数据,计算出倾听者头部水平方向信息,并将其经USB接口传给计算机进行动态双耳声信号合成。心理声学实验表明,本文提出的方法可以消除虚拟声源前后混乱和头中定位现象,提升5.1通路环绕声双耳重放的虚拟声源定位性能。

| Abstract: | This work proposes a scheme for improving binaural reproduction of 5.1 channel surround sound by using dynamic rendering with low cost head-tracking module. The head-tracking module consists of a magnetic sensor and an accelerometer. A microcontroller unit is used to calculate the horizontal orientation of the listener"s head. The orientation data is transmitted to the PC via the serial port for dynamic binaural synthesis. Psychoacoustic experiment indicates that the scheme eliminates the front-back confusion and in-head-localization and therefore improves the localization performance in the binaural 5.1 channel reproduction. |
