7.1.9 Direction of Arrival (DOA)
On the second tab of the MicArray GUI, one can monitor real time the Direction Of Arrival (DOA) as detected by
the algorithm. The DOA also controls the RGB led illumination (i.e.2 active microphones) End users can easily
perform the same DOA detection inside their own software thanks to the 3
rd
party USB library documented in “
USB API/CUSTOMIZATION” section.
DOA Detect / ON = enabled, OFF = No detection and LED control.
DOA Dir = Manual control of the active microphones when DOA is turned OFF
