OPPO, Major Audio Corporates Lead to Form Audio Quality Society


OPPO announce that it will work with the China Audio Industry Association and several of the major audio corporations to launch the Audio Quality Society (AQS) which is part of OPPO’s ongoing efforts to enhance consumers audio experience in the 5G era.

The AQS brings together device vendors, upstream and downstream companies in the headset supply chain as well as audio chip manufacturers and professional testing institutions. The inaugural board members include (in alphabetical order) Bestechnic, China Electronics Standardization Institute (CESI), Edifier, HiBy, HiVi, HIFIMAN, Knowles, MediaTek, Savitech, Xiaomi and vivo. As one of the founders and core technology contributors to AQS, OPPO will serve as a standing board member.

In the past few years, the discrepancies between Bluetooth audio transmission standards and audio codec formats have led to the quality of the audio transmission being to some extent compromised, and therefore, resulting at times in a poor experience for consumers.

The AQS standards aim to break down the barriers posed by wireless audio transmission codec and hardware, enabling the inter-operability of headphones, audio equipment and smartphones. It is expected that it will improve the audio quality of mobile devices and deliver higher quality audio experiences to users.

Liu Jia, Head of OPPO’s Audio Business, commented that OPPO has laid a solid foundation in the audio products space with its MP3 and high-definition DVD players which were recognized in numerous industry awards and worldwide ratings for its excellent sound quality.

“We hope that by forming the AQS, we will be able to build a platform for communication and cooperation among and between market players. We will work with our partners to jointly develop and promote stricter testing and verification standards as well as driving innovation-based development of the high-definition audio ecosystem.”

The AQS technical standards will focus on six major areas to provide users with high-definition and professional sound quality. The electro-acoustic communication standard will ensure voice call quality through the true wireless stereo (TWS) earphone by undergoing 13 kinds of tests. The music sound effect standard supports LHDC (Low-Latency Hi-Definition Audio Codec) as well as precision configuration of subjective and objective listening scores to ensure audio quality. In addition, the AQS technical standards will impose stricter requirements on environmental noise reduction and Bluetooth connection performance, enabling users to enjoy a quieter listening experience under low-latency transmission.

In terms of music experience, the newly designed UI interactive test will ensure that end users are provided as much as possible with an intuitive human-computer interaction. For the three frequent daily usage scenarios of music, call and voice wake-up, the power consumption test system will ensure the endurance of the TWS earphone, with the aim to provide the best user experience.

The AQS technical standards will strive to be reliable across every link in the whole process, from signal emission, transmission, and processing to sound decoding and speaker playback. The result will be a more immersive high-quality audio experience available across number of devices, delivering a smoother mobile multimedia experience in the 5G era.

For years, OPPO has obtained deep insights into consumers’ needs and preferences through its ground-breaking products and services. Employing its extensive expertise in acoustic technology, OPPO will make contribution to the formulation of the AQS technical standards in the three major areas including Bluetooth codec, electro-acoustic communication and music sound effects, in order to strengthen the matching of earphones with smartphones as well as among other audio devices and optimize the human-computer interactive experience. Based on the current evaluation, OPPO expects that its new generation of smartphones and mid-to-high-end audio products will be fully adapted to the AQS standards in the near future.
