The Automotive Audio Bus® (A²B®)* is an emergent technology developed and patented by Analog Devices, Inc. (ADI), and already adopted by a number of key automotive manufacturers.

In addition to a brief overview of A²B, this technote describes the A²B audio testing solution Audio Precision has developed in cooperation with Mentor Automotive. Using an Audio Precision analyzer and the Mentor Automotive A²B Analyzer, you can configure an A²B network for testing the audio performance of A²B-enabled devices. In Technote 135, we’ll use an ADI evaluation board to represent two automotive audio applications.

The discussion will primarily focus on test set-up and connectivity; once the A²B network is established, you can run any audio measurement provided in the APx500 software.

NOTE: This zip file includes the ASIO source and sink session files described in the TechNote.
