Hi:
Making a beamformer with the drawing you made should be possible. Is this a fixed beam that you want to create? What do you mean by Broadway?
There are only 2 positions show in the drawing and no angle or directionality shown for the analog microphone. Can you explain more your application?
Be cautious that any beamforming algorithms would be sensitive to absolute gain and gain tolerances on the microphones.
If you could share more about the application, we might be able to comment further.
Regards
Miguel
