The computation of the time delay of arrival (TDOA) between each of the considered channels and the reference channel is repeated along the recording in order for the beamforming to respond to changes in the speaker. In this implementation it is computed every 250ms (called segment size or analysis scroll) over a window of 500ms (called the analysis window) which covers the current analysis segment and the next. The size of the analysis window and of the segment size constitute a tradeoff. A big analysis window or segment window lead to a reduction in the resolution of changes in the TDOA. On the other hand, using a very small analysis window reduces the robustness of the cross-correlation estimation, as less acoustic fr a mes are used to compute it. The reduction of the segment size also increases the computational cost of the system, while not increasing the quality of the output signal.
