How Automotive Audio Bus (A²B) Technology and Digital Microphones Enable Superior Performance in Emerging Automotive Applications

How Automotive Audio Bus (A2B) Technology and Digital Microphones Enable Superior Performance in Emerging Automotive ApplicationsWithin the automotive in-cabin electronics segment, it’s becoming increasingly clear that the universe of audio-, voice-, and acoustics-related applications is rapidly expanding as car manufacturers attempt to differentiate their vehicles from the competition. Additionally, as average consumers become more tech savvy, their expectations related to both the driving experience and level of personal interaction with the vehicle are expanding significantly. Looking to the future, audible or acoustics-based techniques will become a critical component in Level 4/Level 5 autonomous vehicle engine control units (ECUs) as they attempt to detect the presence of emergency vehicles.

This article is about Automotive Audio Bus® (A2B®) technology explains recent advances in digital microphone and connectivity technologies. These innovations are enabling swift adoption of game-changing applications for future generations of vehicle infotainment systems.
