We present a new device for speaker extraction and physical tracking and demonstrate its use in real conditions. The device is equipped with a dense planar array consisting of 64 microphones mounted on a rotating platform. State-of-the-art blind source extraction algorithms controlled by x-vector piloting are used to extract the desired speaker, which is being tracked by the rotating microphone array. The audience will experience the functionality of the device and the potential of the blind algorithms to extract the speaker from multi-source noisy recordings in a live situation.
