Time-domain Differential Microphone Array (DMA) beamforming
It would extremely beneficial to implement the time-domain approach to Differential Microphone Array (DMA) beamforming as described in “First-Order Differential Microphone Arrays from a Time-Domain Broadband Perspective”, by Buchris, Cohen and Benesty.
This would allow the direct use of directional microphones with the time-domain implementation of the optimal observation filters.
