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.

The implementation has been provided in version v0.5.0. However, it has been noted that the results deviate from those achieved in the literature (“On the Design of Time-Domain Differential Microphone Arrays”, by Buchris, Cohen and Benesty).
So this issue will remain open until better agreement with the literature results is achieved.
