New software release supports connectivity with Mentor’s A2B Analyzer to deliver closed-loop, multichannel A2B audio testing
BEAVERTON, OREGON, December 14, 2017: Audio Precision today announced support, in collaboration with Mentor, a Siemens business, for multichannel audio performance testing of A2B systems and components. A2B (Automotive Audio Bus®) is the digital audio bus technology developed by Analog Devices, Inc. to deliver high-quality audio over an unshielded, twisted-pair wire. By distributing audio and control data together with clock and power over a single wire, A2B significantly reduces the weight of existing cable harnesses (by upwards of 75% in key applications), resulting in improved vehicle fuel efficiency.
Testing Audio Performance of A2B Devices
From simulation and bench testing in early-stage development, to validation and production testing, having a closed-loop system to measure audio and dynamic signal performance over an A2B network is an integral part of incorporating the bus technology into next-generation automotive systems. By combining the capabilities of Audio Precision’s APx500 audio analyzers and software, and Mentor’s A2B Analyzer System, software and ASIO driver, developers can easily create a complete, closed-loop multichannel A2B audio test system.
Within this test system, the Mentor analyzer platform provides straightforward A2B network configuration and simulation, as well as flexible routing, and high-fidelity audio. The APx audio analyzer delivers comprehensive, multichannel audio measurement analysis and offers a wide range of interface options, including analog, Bluetooth®, digital serial (TDM) and PDM. Working as a complete system, these tools eliminate the effort required to develop, and support, in-house, custom test solutions.
“Audio technology—whether for hands-free calling, active noise cancelling or passenger entertainment—is an integral part of the automobile’s continued evolution as a technology platform,” stated Dave Schmoldt, Audio Precision CEO. “We’re thrilled to support automotive developers as they seek to evaluate, and incorporate, A2B into the design of their vehicles, sub-systems, and components.”
Mentor is a long-established automotive systems supplier, engaged with nearly every leading OEM and Tier 1 supplier, and providing design tools and embedded software in the areas of connectivity, electrification, autonomous drive and vehicle architecture.
