Shanghai, March 27, 2026 — Dolby Laboratories, a leader in immersive entertainment experiences, and Tencent Music Entertainment Group's leading music streaming platform QQ Music today jointly announced plans to introduce a new upgrade of Dolby Atmos technology for the QQ Music mobile app through Dolby's flagship audio codec technology — Dolby AC-4. With this upgrade, QQ Music will become the first mainstream music streaming platform to support the latest upgrade of Dolby AC-4, marking another important milestone on the path to providing high-quality immersive music experiences at scale.
With the support of Dolby AC-4, QQ Music's Dolby Atmos continues to optimize, enhancing the experience in fidelity and accuracy while better preserving the artistic intent of the creators than ever before. The music remains vibrant, multidimensional, and emotionally charged, bringing listeners closer to the artistic expression behind each piece.
Key upgrade features include:
Faithfully presenting artistic intent with exceptional fidelity: With the support of Dolby Atmos, every detail heard by listeners from the original mix can be preserved with quality comparable to professional studio standards. Vocals, instrument sounds, and spatial elements are restored with clear layers and depth, allowing the music to be presented as precisely as the artist intended — capturing every subtle detail, emotional rhythm, and sonic impact. Comprehensive upgrade of the headphone listening experience: Building on the familiar Dolby Atmos experience, this upgrade brings a clearer and more natural sense of space. Vocals and instrument sounds are precisely positioned in the sound field, without any sense of crowding or constriction. The sound field performance is more stable and clear, with details and layers distinctly discernible.
Javier Foncillas, Vice President of Business Development and Global Sales at Dolby Laboratories, stated: “As streaming platforms become the primary medium for music consumption, the quality of the audio experience is more important than ever. Our collaboration with QQ Music to introduce the latest upgrade features of Dolby AC-4 is a strategic move in line with this trend. Together, we will bring listeners a higher level of audio fidelity and clarity while providing artists and record companies with a more powerful and reliable platform to carry their creative intent.”
Zhou Wenjiang, Vice President of Technology at Tencent Music Entertainment Group QQ Music &amp; Kuwo Music, stated: “TME is always committed to embracing cutting-edge innovation to provide users with extraordinary experiences. Our long-term collaboration with Dolby has always aimed at continuously expanding the possibilities of music platforms. This time, QQ Music once again takes the lead in integrating the latest upgrade of Dolby AC-4, bringing higher fidelity, clearer, and more nuanced experiences to platform users, setting a new benchmark for streaming music platforms, allowing users to enjoy immersion while
&#34;Experience the most authentic charm of music.&#34;
The long-term collaboration between Dolby and Tencent Music Entertainment Group began in 2022, when QQ Music became the first Chinese music platform to support Dolby Atmos. Since then, the cooperation has deepened, and in 2023, QQ Music became the first music platform in China to support both Dolby Atmos and Dolby Vision. The Dolby Atmos music service has also expanded to a wide variety of terminal devices, including mobile phones, computers, televisions, and even cars, allowing users to enjoy their favorite music in Dolby versions anytime and anywhere. Building on this positive momentum, Tencent Music Entertainment Group has further expanded the Dolby Atmos music service to more of its platforms, including Kugou Music, Kuwo Music, and the international market-oriented JOOX
