Figure 4
Plot of SNR as the unmixing matrix coefficient is varied, for the two channels shown in Figure 3. The first (a) fixes the primary microphone as constant and adds the secondary microphone scaled by . The second (b) fixes the secondary microphone as constant and adds the primary microphone scaled by . Both yield approximately the same peak.
