Voice and Acoustic Signal Processing
Voice and Acoustic Signal Processing Solutions
Analog Devices understands that an immersive, in-cabin audio experience is one of the primary differentiators in purchasing a car.
From infotainment to hands-free communication, with a person or with a machine—think Siri, Alexa, or OK Google—we have utilized its sophisticated IP to develop ADI LISTN™, a portfolio of high-performance microphone audio signal processing software solutions that fulfill the highest automotive industry standards.
Value and Benefits
With a mature IP equipped on millions of cars on the road, the ADI LISTN solution is easy to integrate and tune, reducing your time to market. Its performance-leading software is flexible, customizable, and supports any hardware platform. It offers hardware implementations that are resource efficient as well as optimized hardware implementation, resulting in high-quality processing and deterministic performance with low latency.
In addition, our solution provides compliance with the highest automotive quality standards (ITU-T p.1100/1110/1120/1140) that pass multiple Apple CarPlay and Google Android Auto certifications, reduced evaluation time and time to market, and minimization of error rates, our portfolio enables exceptional performance not only in human communication, but also when processing audio before the recognition engine receives it.
All ADI LISTN software is available as building blocks in SigmaStudio®, and as libraries for integration with CrossCore® Embedded Studio (CCES), on ADI SHARC® DSPs, or any tool chain as required for compiling on a third-party CPU or SoC.

Audio Signal Processing Software Tools
ADI LISTN Tuning Tool
The ADI LISTN tuning tool is a graphical user interface (GUI) that connects to the target via Ethernet, UART, or SPI. With the ADI LISTN automotive audio signal processing suite and its tuning capabilities, it is easy to create a system that passes the relevant automotive specifications such as ITU-T p.1100/1110/1120/1140 and Apple CarPlay.
SigmaStudio
The SigmaStudio® graphical development tool is the programming, development, and tuning software for the SigmaDSP® and SHARC audio processors and A2B transceivers. Familiar audio processing blocks can be wired together as in a schematic, and the compiler generates DSP-ready code and a control surface for setting and tuning parameters.
CrossCore® Embedded Studio (CCES)
CrossCore Embedded Studio is a world-class integrated development environment (IDE) for the ADI Blackfin®, SHARC, and Arm® processor families. CCES also offers Blackfin and SHARC developers highly integrated add-in support for drivers, services, and algorithmic software modules.
