Source code implementation of one-dimensional MUSIC algorithm for microphone array-based sound source localization, featuring signal processing workflow and eigen decomposition methods

Detailed Documentation

This document provides the source code implementation for a one-dimensional MUSIC (Multiple Signal Classification) algorithm designed for sound source localization using microphone arrays. The algorithm achieves precise localization of sound sources through advanced signal processing techniques, including covariance matrix computation, eigenvalue decomposition, and spectral peak search. This capability is crucial for numerous applications, such as enhancing the accuracy of speech recognition and voice command systems, or optimizing audio performance in concert halls and lecture environments. The implementation includes key functions for array signal processing, steering vector calculation, and MUSIC spectrum generation. We believe this complete codebase will benefit engineers and researchers across various fields by providing a foundational implementation that can be extended for further study and optimization of acoustic localization systems.
