The VCO1S A²B Analyzer system is designed specifically for development teams servicing automotive OEMs, automotive suppliers, and audio connectivity equipment suppliers. The deterministic nature of the A²B technology makes it particularly well-suited for automotive audio devices (active speakers, microphones) and newer applications, such as active noise cancellation (ANC), in-car communication and infotainment.
The A²B Analyzer system consists of a compact hardware device, an accompanying C library software development kit (SDK) and network configuration and simulation tools. The hardware device includes a USB 2.0 interface for PC connectivity for audio data and command/control functions. The small form factor device also features a variety of popular audio and connectivity peripherals.
