SPARK Microsystems is set to showcase a revolutionary wireless audio transmission technology at the upcoming AES Show 2024 NY that could fundamentally change wireless audio capabilities. The Canadian fabless semiconductor company claims its ultra-wideband technology can deliver audio quality indistinguishable from wired connections, representing a significant advancement beyond current Bluetooth limitations. The demonstration scheduled for October 10 will feature presentation by audio industry expert Jeff Anderson sharing results of extensive third-party analysis comparing SPARK's UWB digital audio performance to digital wire transmission.
The technology exhibits bit-perfect fidelity with transmission rates up to 24 bits and 96Ks/s, delivering uncorrupted audio bit depth at ultra-low latency. This allows headsets, speakers and other audio equipment to achieve wired-like sound quality without physical constraints. Attendees will experience this firsthand through demonstrations of SPARK's headset demo kit supporting up to 96kHz stereo audio and 48kHz 16-bit microphone back channel with remarkably low latency of less than 7ms. This performance level makes the technology particularly suitable for applications requiring clear, uninterrupted communication where traditional wireless solutions have fallen short.
SPARK's audio technology reportedly outperforms legacy Bluetooth in several key areas including data throughput, latency and power efficiency. It also claims advantages over Wi-Fi-based audio technologies in terms of lower latency and significantly reduced power consumption, potentially leading to longer battery life in wireless audio devices. The implications could be far-reaching for the audio industry, potentially paving the way for a new generation of wireless audio devices that offer the quality of wired systems without physical limitations. This could be particularly impactful in professional audio settings where fidelity and low latency are crucial for both recording and live performance applications.
The technology has already gained recognition from prestigious audio brands including Focal and Sonus Faber who have incorporated SPARK's UWB technology into their products, suggesting growing industry acceptance of this innovative approach to wireless audio transmission. Beyond audio quality improvements, the elimination of wires while maintaining high-fidelity sound could lead to more flexible and adaptable audio setups in various environments from recording studios to live performance venues. The improved power efficiency could also contribute to development of more sustainable and longer-lasting wireless audio devices as the industry continues evolving toward wireless solutions.
