Audio Vivid Hits 1 Million Vehicles, Accelerating the Global Shift Toward 3D In-Car Audio

November , 2025, the UHD World Association announced a major milestone for the in-car adoption of the spatial audio standard Audio Vivid: the number of vehicles equipped with the technology has officially surpassed one million units.

A Global Breakthrough: Audio Vivid Becomes One of the World’s Four Leading 3D Audio Standards

As the world’s first audio codec standard built on AI technology, Audio Vivid has joined Dolby AC-4, MPEG-H, and DTS-UHD as one of the four major global 3D audio standards, and was officially adopted as a national standard in August 2025.

To deliver a stable and immersive listening experience in complex driving environments, Audio Vivid builds a complete solution for automotive spatial audio powered by cutting-edge acoustic processing technologies.

Key technological breakthroughs include:

• Support for 7th-order HOA binaural rendering and 128-track real-time audio rendering
• End-to-end codec latency reduced to below 80 ms, with binaural rendering latency further lowered to under 40 ms
• A wide sampling-rate range from 32 kHz to 192 kHz, ensuring high-fidelity output even under high-speed noise conditions

On top of this robust technical foundation, Audio Vivid introduces a transformative enhancement to the in-car listening experience:

• Breaking free from traditional channel-based limitations, it enables precise positioning and free movement of sound objects in 3D space
• With its unique “Golden Listening Position” feature, users can select their preferred seat to optimize sound rendering, allowing every passenger to enjoy a personalized immersive audio experience

Audio Vivid also demonstrates exceptional adaptability across multiple scenarios. After undergoing extreme testing in live music festival environments, key signature capabilities—such as its distinctive high/low frequency drum separation—have been successfully migrated into the automotive use case. This innovation not only elevates music enjoyment but also allows for more accurate localization of environmental sounds, enhancing safety during driving.

Industry Adoption: Increasing Automaker Partners and Rapid Expansion

Driven by accelerating industrialization, vehicle installations of Audio Vivid have exceeded one million units, with more than ten major automakers—including HarmonyOS Smart Vehicles, Chery, Great Wall Motor, GAC, Avatr, Deepal, and Voyah—already adopting the technology.

• 29 vehicle models currently support Audio Vivid
• Expected to expand to 35 models by the end of the year

Leveraging UWA’s network of 480+ global member enterprises, technical integration with most mainstream automotive brands has been completed, enabling a continuously expanding ecosystem.

These achievements highlight Audio Vivid’s broad compatibility across vehicle types and price ranges, setting a new benchmark for in-car audio quality.

Ecosystem Deployment: Building a Full “Standard–Content–Devices” Value Chain

On the content side, Audio Vivid has partnered with major platforms including NetEase Cloud Music, Himalaya, and Huawei Music, creating a massive catalog of:

• 8 million+ music tracks
• 3,300 hours of Audio Vivid spatial audio drama content across more than 20 popular genres (film/TV IP, parenting, mystery, etc.)

The ecosystem also enables seamless “person–vehicle–home” experiences:

• Deep compatibility with smart screens, headphones, and IoT devices
• Full adaptation for automotive versions of CCTV Video and Yunting, ensuring a consistent immersive experience across all user scenarios

International & Regulatory Recognition: A Chinese Standard Reaches the World

Audio Vivid has passed the IEC 61937-17 international certification and has been recognized by the International Telecommunication Union (ITU).

According to Vincent Zhang, Secretary-General of UWA, the association is committed to building a comprehensive standards system across the entire audiovisual chain and accelerating the deployment of UHD technologies across all industries.

• 153 ecosystem enterprises now support HDR Vivid
• 122 ecosystem enterprises support Audio Vivid
• 1,675 devices have completed Vivid certification
• 23 color-grading studios and 29 mixing studios certified for content production
• Audio Vivid has been included in procurement specifications for top telecom operators’ set-top boxes, enabling adaptation across 70+ million terminals

A Landmark Transition: From Technological Leadership to Market Leadership

With the milestone of one million equipped vehicles, Audio Vivid is building a strong technological moat for audio industry.

This audio standards are now advancing along the path of “technological innovation → scenario validation → scaled deployment → global standardization”, accelerating rapidly in the global UHD audiovisual lan
