AES67
R&D Background
Currently, there are numerous types of audio protocols on the market, but their
development concepts fail to effectively respond to the evolving trends of
platformization, digitalization, networking, professionalization, and
ecologicalization, let alone achieving efficient docking and centralized control.
Closed and semi-closed proprietary protocols have emerged in large numbers
in the market, but due to their limited service scope, user satisfaction remains
low. Meanwhile, integrated chips spanning audio and video face technical
barriers in protocol docking, and their prices remain high.
To overcome the long-standing technical challenges in the industry, such as
incompatible audio protocols, difficult network adaptation, lack of ecological
deployment, low interface openness, and dependence on professionals, and to
quickly penetrate both existing and growing markets, Soundking relies on the
industry-standard RAVENNA/AES67 as its foundation to drive innovation and
upgrading of system products. With core technologies such as modular channel
scalability, autonomous DSP redundancy backup algorithm mechanism,
voiceprint large model I/O separation, and IoT visualization as its mission for
industry development, Soundking also ensures good compatibility with other
mainstream audio and video protocols worldwide. Through integration with IoT,
it can achieve technical control of the overall audio ecosystem, opening up
broader market space for the industry.
This series of products is widely applicable to various settings such as
government agencies, radio and television stations, transportation hubs, sports
venues, theaters, military units, schools, and theme parks.
