WICC 2021 is about to be held in Lychee, will reveal the key technology of high-quality experience

On July 24th, the 3rd Global Internet Communication Cloud Conference (WICC 2021) hosted by Rongyun, a leading global Internet communication cloud manufacturer, will be held in Beijing Park Hyatt Hotel. At present, more than 1,000 developers have signed up to participate in the conference. Their greatest benefit is not only to listen to the technical leaders of the main forum, but also the afternoon technical sub-forum, advanced technologies and best practices shared by technical leaders in the industry, these insights It will stimulate more industrial vitality and drive and accelerate the development of the communications cloud industry.

In the technical sub-forum of scene-based empowerment and innovation, China's online audio platform Lizhi (LIZI.US) will be brought by senior audio engineer Ma Pengfei to share the technology of "Litchi Audio Experience Optimization Evolution" to explain the Lichee recording/live broadcast live for developers The evolution of the architecture and how to improve the audio quality and other core technologies of Lychee are very much to look forward to.

Demystify the core technology for optimizing high sound quality

The technology sub-forum of scenario-based empowerment and innovation mainly brings developers the sharing of scenario-based best technical practices. As the speaker of this audio scene, Ma Pengfei, after joining Litchi, he is mainly responsible for the client's audio collection, algorithm processing, codec, sound rendering, adaptation of various types of models, etc., and provides corresponding audio solutions around the interactive entertainment industry The program ensures high-quality sound effects in live broadcast, recording and other scenarios, and has accumulated rich practical experience.

Technology sharing is the purpose of his participation. He bluntly said, "In the field of pure audio, there are not many who really do the technology thoroughly. The advantage of Lychee lies in the sound processing technology. Our original intention is to connect all people with sound. Together. So in terms of sound quality, it is necessary to work hard, to refine the work, and to continuously optimize ordinary sound quality into high sound quality in different application scenarios, and to bring users the best experience." During the sharing, he will talk about the popular high sound quality The live broadcast scene is explained. Among them, how to deal with the key data in sound playback is the main technical highlight.

In addition, Litchi also has a unique voice intelligent recommendation technology, which can recommend corresponding anchor programs or music to customers in a targeted and more accurate manner according to the tone and language. For example, according to the language, you can recommend programs in English, Korean, and dialects. Combining the application scenarios of sound intelligent recommendation technology, Litchi will reveal how to polish the core technology of high sound quality, and achieve the best sound quality in the current scene through a refined sound quality configuration scheme.

Differentiated competitive thinking makes lychee "true fragrance", which is also a reference for developers

The online audio market has increased significantly due to Clubhouse's fire at the beginning of the year, and it has once again attracted great attention as the "first stock of China's online audio industry".

Since its establishment in 2013, Litchi has been committed to letting people connect people with sound through its product portfolio. After several years of technical polishing and deep market cultivation, it has cultivated products suitable for different user groups, including the main UGC audio community Litchi App. ; Litchi podcast, which focuses on disseminating premium podcast content and exchanges at home and abroad through big V. Litchi uses diversified and differentiated application products to get stuck in advance, occupying the first-mover advantage.

The success of Litchi once again confirms that "opportunities always favor those who are prepared." For developers, what is important is not to follow the market, but to specialize in technology. Once they aim at the direction of research and development, they must sink without distraction, continue to explore and polish. In any technical field, it takes time and experience to be refined. This is Ma Pengfei's advice to developers with his personal professional experience.

In terms of technical integration practices, his advice to developers is: the best is the best. The technology itself is not good or bad. If you want to integrate a good product, you may face many technical solutions, each with its own advantages and disadvantages. No one solution can meet all scenarios. Therefore, it is necessary to find the most suitable one in the actual development and verification. Be the best solution.

The main purpose of WICC is to promote exchanges, not only among the many technical leaders and developers of WICC, but also among various manufacturers in the industry.

In the future, Litchi will make a strategic layout in terms of the call experience of on-board terminals and the high-quality audio technology of VR scenes. Litchi also hopes to further strengthen exchanges and cooperation with the industry through the WICC technology event, and promote the development of the entire audio industry in the direction of higher quality experience.

Concluding remarks

This WICC conference focuses on real-time audio and video as the main technology sharing. In addition to Litchi Ma Pengfei, the audio-related technical content includes "New Progress in Communication Acoustics" by Li Xiaodong, a researcher at the Institute of Acoustics of the Chinese Academy of Sciences, and Zang Qilong, a senior developer of Rongyun iOS "Exploring the evolution direction of a new generation of PaaS services based on the language chat room scene SDK" and so on. How will the conference "wake up the ears" at that time, let us wait for WICC 2021.
