Improving Sound Source Localization Accuracy Through Steered Response Power Techniques: A Comprehensive Review

The Steered Response Power (SRP) method is a widely used technique for sound source localization that can provide satisfactory performance in moderately reverberant and noisy scenarios. This work presents a comprehensive review of over 200 papers on SRP and its variants, with a focus on improving the method's computational efficiency, robustness in adverse environments, and ability to localize multiple sources.
