Immersive Acoustics via Next-Generation Networks: Achieving High-Fidelity Audio in the Metaverse

The rapid evolution of the Metaverse demands integrated solutions that merge advanced telecommunication networks with immersive audio technologies. High-fidelity, low-latency audio transmission relies on robust network infrastructures such as 5G, emerging 6G, network slicing, and edge computing that deliver high throughput and ultra-reliable connectivity. This paper investigates how these advanced networking technologies can be synergistically combined with state-of-the-art acoustic rendering techniques, including spatial audio and binaural processing, to enable immersive audio applications in the Metaverse. By analyzing key application scenarios and mapping critical performance indicators for both network and acoustic quality, we highlight the pivotal role of telecommunication advancements in meeting the stringent requirements for real-time, immersive experiences. Open challenges and future research directions are discussed, emphasizing the convergence between next-generation networks and immersive audio to shape the future of interactive virtual environments.
