In article number 1902271, Jun Yang, Han Jia, and co‐workers propose a multi‐source listening system using a microphone with a metamaterial enclosure. The system not only realizes the sound localization and separation in 3D space, but also presents a great real‐time performance in source identification and tracking. The effectiveness of the system is experimentally proven in multiple real scenarios.
