Microphone Array Sound Source Localization Delay Estimation Algorithm

This article explores the implementation of delay estimation algorithms for microphone array sound source localization and their applications in acoustic source positioning. These algorithms enable microphone arrays to accurately locate sound sources, thereby enhancing the precision of speech recognition and audio processing systems. We examine various aspects of the algorithm, including its comparative performance metrics and methodologies for identifying the most effective algorithm. The implementation typically involves calculating time difference of arrival (TDOA) between microphone pairs using cross-correlation techniques, with key functions including signal preprocessing, peak detection in correlation plots, and coordinate transformation. Additionally, we investigate how to integrate this algorithm with other localization methods such as beamforming or MUSIC algorithms to achieve superior results. Finally, we discuss future development directions for delay estimation algorithms and their potential applications in other domains such as robotics, surveillance systems, and acoustic monitoring. Through this article, readers will gain comprehensive understanding of microphone array sound source localization delay estimation algorithms and appreciate their critical importance in modern audio processing applications.
