Taking the famous Qingdao Shadow Capital Project as an example, he introduced how Wanda Travel has selected technology and equipment systems in large-scale performing arts venues. He also shared the technical details of using the variable reverberation technology to complete the function transformation in the large-scale multi-purpose performance hall. Everyone showed great interest in his speech and raised many issues of concern to everyone. They all said that they have the opportunity to visit the Oriental Film City and listen to the wonderful sound of the largest variable reverberation hall in China.

The technical exchange activities in the afternoon are very colorful. Qiao Yue and Lin Jing, who rushed from the Peking University Laboratory, brought a spherical 3D microphone system. They first introduced the development process and results of this project. This is one of the key experimental projects of artificial intelligence of Peking University School of Information. It is hosted by Professor Qu Tianshu and guides students to develop. This achievement has already published academic papers and applied for patents. Everyone listened with great interest to the system's live pickup and playback through headphones, giving high praise. It has a very clear sound quality and very detailed and accurate sound orientation. Everyone is very interested in its application in practical situations, and put forward some suggestions for improvement.
