aishoot/Sound_Localization_Algorithms ? reverse-engineered prompt

Build me a small sound source localization project that lets me compare a few classic methods on microphone array data. I want beamforming, GCC PHAT, SRP PHAT, MUSIC, ESPRIT, and MVDR, with clear examples showing how each one estimates direction of arrival and how the results differ.

Please make it easy to run the demos, with simple scripts or notebooks, and include a clear example using a microphone array so I can see 2D or 3D localization plots and spectrum style outputs. If there are multiple versions of MUSIC, keep the best one as the main example and make the others easy to inspect. Add short explanations in plain language so I can understand what each method is doing, and include sample results or figures if possible. If anything is unclear, look up current docs or references online and use the most practical approach.
