摘要
利用ADSP BF533 DSP处理器设计了一种二维声源定向系统。系统基于声波到达时间差技术,采用相位匹配算法,对两个传声器采集的声音信号进行分析。通过算法仿真验证了算法的可行性和准确性,并将算法在DSP上实现。
A two-dimensional sound source orientation system is designed with ADSP BF533 DSP as its processor.Analysis of the voice signal from two microphones is made using phase-matching algorithm,based on the technology of time delay of arrive（TDOA）.The paper emulates the feasibility and accuracy of the algorithm,and then implements it on DSP.
