Once the TDOA values of all channels have been computed, we have seen above that it is desirable to apply a TDOA post-processing to obtain the set of delay values to be applied to each of the signals when performing the filter-and-sum as proposed in eq. 2.33. We propose and implement two different filtering steps: Noisy TDOA detection and elimination (TDOA continuity enhancement), and 1-best TDOA selection from the M-best computed vector.
