Setup

This is the same example as the third example with more reverberant walls: the room size is 3x4x3 m and the reverberation time is 0.5sec. Room

Discussion

In the more reverberant condition (compared to the third example), the Mod-MFCC based features create a less than ideal cluster for source 1, as well as missing the best SINR microphone for source 2. The speaker embedding based features consistently deliver good (logical) clusters
