Abstract :
Target sound orientation plays an increasingly important role in modern war. This paper introduces a target sound orientation system based on multichannel sound card. It research on the MFCC feature parameters extraction, HMM algorithm for sound recognition, and time delay estimation based on LMS adaptive filter. The system is easy to build and extend with high accurateness.
