Abstract
Sound source localization in real time can be employed in numerous applications such as filtering, beamforming, security system integration, etc. Algorithms employed in this field require not only fast processing speed but also enough accuracy to properly cope with the application requirements. This work presents accuracy benchmarks of a hybrid approach previously proposed, which is based on the Generalized Cross Correlation (GCC), and the Delay and Sum beamforming (DSB). Tests were performed considering a linear microphone array simulated in MATLAB. Analysis through variations in array size, number of microphones, spacing and other characteristics, were included. Results obtained show that the proposed algorithm is as good as the DSB under some conditions that can be easily met.
