SPARK Microsystems' UWB Technology Achieves Bit-Perfect Wireless Audio Transmission

SPARK Microsystems has released third-party analysis demonstrating that their ultra-wideband technology achieves bit-perfect wireless audio delivery with ultra-low latency under 7 milliseconds. The research conducted by independent audio engineering consultant Jeff Anderson compared SPARK's UWB technology to competing audio codecs including LDAC, aptX HD, aptX LL, and SBC using Fast Fourier Transform measurements with wired equipment as the reference standard.

The findings reveal that SPARK's UWB technology delivers audio indistinguishable from wired transmission while Bluetooth codecs showed elevated noise floors, noticeable distortion at higher frequencies, and latency ranging from 30 to 200 milliseconds. This breakthrough has significant implications for the audio industry with high-end brands including Sonus Faber and Focal already adopting the technology in their products. Rejean Bedel, Groupe Marketing Manager at Focal, described this advancement as marking a turning point for high-end audio enabling seamless wire-free products without sound quality compromise.

Beyond superior audio quality SPARK's UWB technology offers bi-directional audio transport supporting an additional bit-perfect low-latency uncompressed audio back channel. Frederic Nabki, Co-founder and CTO of SPARK Microsystems emphasized that for decades the industry accepted compromises in sound quality latency and energy efficiency to make wireless audio possible but their low-power UWB technology changes this dynamic delivering bit-perfect audio exactly as encoded at the source.

The timing of this breakthrough is crucial as demand for high-fidelity wireless audio solutions grows amid increasing wireless interference. SPARK's technology provides unparalleled stability and performance while being optimized for low power consumption making it ideal for battery-powered devices. This combination of superior audio quality ultra-low latency and energy efficiency positions SPARK's UWB technology as transformative for the wireless audio market potentially reshaping consumer expectations and industry standards.
