摘要
DirectSound提供了强大的音频处理功能,使得开发者在不需要知道声卡硬件细节的前提下开发出高性能的多媒体程序。本文结合笔者的开发实例,详细阐述了使用DirectSound实现实时音频采集的方法,并设计实现了基于时延估计算法的声阵列定位系统。
With powerful audio processing function provided by DirectSound, the high - quality multimedia software can be designed even without details of hardware. In this paper, the way of real time audio acquisition and the acoustic array location system based on time delay algorithm are discussed. The experimental results show the effectiveness of real - time localization system.
