Can obtain the angle information of moving source in the stereo field using four microphones and the module of adaptive beam forming in SigmaDSP?

As discussed in “SigmaDSP Two Microphone Beamformer(, a new algorithm has been created for the ADAU1761 that will take two microphones and adaptively beamform in order to directionally focus on an audio source in the stereo field. However, the output of the beamformer is the enhanced source signal, can we directly obtain the angle information of  moving acoustic source, just like the algorithm of Multiple Signal Classification (MUSIC)? In our project, we plan to obtain the angle information of moving acoustic source by use of  four microphones and ADAU1761, could you provide same recommendations or some demos?
