News Content:
On December 7th, 2023, the Zhong关村 Audio-Visual Industry Technology Innovation Alliance approved and released the “Informational Technology – Virtual Reality Content Expression Audio” (Standard No. T/AI 125-2023) group standard. The standard was jointly drafted by 18 enterprises, including TikTok, WeChat, Xiaomi, Huawei, and more.
The standard describes the metadata, renderers, and data flow methods required for virtual reality audio expression. It supports 3DOF and 6DOF virtual reality scenarios and other necessary technologies. All the technologies in the standard have undergone third-party testing and verification, including formal verification, functional verification, and subjective testing for rendering effects. They have also been system-validated in actual systems. This standard will be released first as an AVS group standard and is expected to be promoted to a national standard and an IEEE international standard.
The release of this standard fills the gap in domestic virtual reality audio technology standards and aims to play a key role in the development of related international standards. This standard will be released first as an AVS group standard and is expected to be promoted to a national standard and an IEEE international standard.
