Developed and optimized an end-to-end audio localization system for the ECLAIR-Robotics/crackle repository, focusing on real-time sound direction estimation using multi-microphone arrays. Leveraging Python and Arduino C++, the work integrated sensor data acquisition, FFT-based audio analysis, and cross-correlation algorithms to enable robust time-difference calculations and 3D localization. The system featured dynamic Arduino port detection, ROS2 publishing for real-time visualization, and modular code organization for maintainability. Emphasis was placed on data integrity, code refactoring, and debugging support, resulting in a scalable pipeline suitable for robotics applications and future machine learning integration, with enhancements to both hardware interfacing and software reliability.
