| Abstract: | 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. |
