Today's technical discussion session was the keynote address of the event's organizer, Luo Fei, the head of the audio and video field of Wanda Travel, who was the "New Challenge for the Liberal Business Format - Audio Video Project". 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.

Next, Xie Yong from XYCAD shared their newly developed intelligent network platform—AVL-Top Through this platform, the initial configuration scheme of the sound system applied in different occasions can be simply customized, and a simple and effective tool for the system quotation scheme is provided for the suppliers who are engaged in the fixed installation system. Everyone thinks that this tool is very creative and practical, and it also proposes some suggestions for its application.

Professor Wang Zexiang, the chief expert, and Liu Zili, the director of the R&D department, gave a speech on the theme of "Listening of Listening — Impact of Monitor Speakers on Program Quality". The two lecturers elaborated on the technical performance indicators that the monitor speakers must meet, and clarified some basic concepts of audible electroacoustics. It also vividly describes the performance and anecdotes of various brand monitor speakers in the recording of the program over the years. Everyone expressed their appreciation for such training camp courses. It is recommended to hold special lectures to consolidate your basic knowledge and improve professional skills.
