Fig. 3From: DOA-guided source separation with direction-based initialization and time annotations using complex angular central Gaussian mixture modelsThe noise suppression masks \(\mathcal {M}^{\text {noi}}_{j}(f,t)\) are determined based on each of the J outputs of the initial source separation after time aligning the channels for the respective target DOA. The combination of these steps yields the initial masksBack to article page
