In today's rapidly evolving technological landscape, audio plays a crucial role in enhancing user experiences across various domains, from entertainment to communication and beyond. The demand for low-latency and high-fidelity audio has never been higher, as users increasingly expect seamless, immersive, and crystal-clear sound. Especially technologies such as Bluetooth Low Energy (i.e., Bluetooth LE Audio) and ultra-wideband (UWB) are at the forefront of addressing these requirements, promising a future where audio experiences are more immersive, synchronized, and personalized than ever before. As these technologies continue to evolve and integrate into various ecosystems (including high-end smartphones, tablets, and modern vehicles), they hold immense potential for revolutionizing the audio industry and improve our daily interactions with technology. Within this context, we aim to study and quantify the performance offered by UWB technology in terms of suitability for low-latency and high-fidelity audio applications, in order to understand which advantages and disadvantages it offers compared to classical solutions based on Bluetooth Low Energy.
