Effect of β on SRP-NMF performance. Subplots show the histograms of SRP-NMF on a mixture of 4 sources taken from SiSEC database (dev1_male4_liverec_250ms_5cm_mix.wav) with DT=35 and β varying from 0 to 80. β is displayed on each of the subplots. The x-axis shows DoA (degrees). The y-axis is the (normalized) frequency of DoAs
