Hi there,
For DOA, there are 2 ways, one is Step 4. DOA(Direction of Arrival) on <LINK_TEXT text=“http://wiki.seeedstudio.com/ReSpeaker_C … e-solution”>http://wiki.seeedstudio.com/ReSpeaker_Core_v2.0/#open-source-solution</LINK_TEXT>. the other way is <LINK_TEXT text=“http://respeaker.io/librespeaker_doc/cl … sNode.html”>http://respeaker.io/librespeaker_doc/classrespeaker_1_1VepDoaKwsNode.html</LINK_TEXT>
If you only do the doa, the respeaker mic array v2.0 shall be better solution. thanks.
Bill
