bf3 - beamformer algorithm 3, voice pitch FFT bin phase delay and sum See Also: bf2.m, SLABForm BF3, bfpitch.m BF2 is a standard xcorr-based delay and sum beamformer. BF3 is also a somewhat standard delay and sum beamformer but the delays are extracted from FFT phase at the voice pitch period rather than using an xcorr. The hope was to improve performance in reverberant environments. This project was paused shortly after the initial version of the algorithm was developed.
