Distance between microphones for respeaker 4-mic array for raspberry pi

hrishikesh.iitmandi · January 24, 2020, 5:55am

Does anyone know the distance between the microphones of the Respeaker 4-mic array(for raspberry pi), I tried using the .dxf and .skp files to measure distance but they were giving me values like 2081 meters.

I have been using ODAS to do beamforming, but the results are always bad. I think that the config file is wrong in terms of distance between microphones.

Any help would be greatly appreciated.

Thank in Advance

Hi,

when I checked the provided dxf file , it gave me around 58.298 mm from one mic centre point to another mic centre point.
