Task

Automotive consumer expectations have increased dramatically over the past decade. This is true not only for high-performance branded sound systems, but also for non-branded sound systems. A superior audio system and an effective soundscape with customized chimes and alerts can enhance the ownership experience and help establish an automotive brand's identity.

With many OEMs and Tier 1 suppliers focused on delivering maximum value to consumers, audio systems are often not prioritized due to the cost and additional engineering expertise required. Branded audio is typically out of reach for more value-conscious market segments, meaning engaging, customized audio experiences have traditionally been limited to premium models and higher trim levels.

FEATURES AND BENEFITS OF ADI LISTN EZ-AUDIO SOLUTIONS

Analog Devices, Inc. now offers the ADSP-21562-AUTO board, designed to deliver premium audio for automotive head unit applications. The ADSP-21562 audio processor is an upgrade from its predecessor, the SHARC core, with a powerful SHARC+ DSP core that natively supports double-precision floating-point arithmetic. The built-in Audio Weaver library is optimized for the SHARC+ architecture, including leveraging the on-chip FIR/IIR accelerators.

DSP Concepts' Audio Weaver is an audio experience design platform that accelerates in-vehicle audio development, fosters product team collaboration, and makes audio innovation easier. This low-code embedded platform reduces risk and complexity with drag-and-drop host applications used for functional design and audio processing libraries built on high-performance SHARC+ DSP cores. With these tools, Audio Weaver assists automotive audio designers at every step from prototype to production.

The ADI LISTN EZ-AUDIO system includes AWE Tune™, a full-featured automotive audio tuning system that works in conjunction with Audio Weaver. With an intuitive graphical user interface, AWE Tune makes it easy to customize and iterate on your audio system by tuning multiple channels simultaneously, creating and duplicating presets, locking already defined presets, and more. CPU load monitoring and tuning report generation allow developers to ensure their system has enough headroom to manage all of Audio Weaver's signal flow.

With these products packaged as an integrated solution, ADI and DSP Concepts provide a complete, optimized toolkit that works right out of the box and can be customized as needed. Optimized built-in libraries allow for trouble-free and efficient development and include all the tools you need to test and tune your system.

A single combined hardware and software solution allows OEMs to easily apply fully featured, pre-configured audio layouts with the required user controls and features to any vehicle cabin.

• Stereo entertainment audio output with up to 12 speaker channels
• Volume/Mute/Balance/Fade/Tone Control
• Speed compensated volume adjustment
• Full matrix mixer for entertainment channels with delay, gain and hardware accelerated IIR EQ
• Fully featured chimes and prompts

Customer Experience

OEMs looking to deliver cost-effective vehicles are often forced to deprioritize entertainment systems because they require additional software integration expertise, audio teams, and specialized tools for system tuning. Speed to market is critical, and cost-effective, hassle-free solutions are required.

The ADI LISTN EZ-AUDIO system solves these challenges simply and quickly. By contacting ADI to obtain an evaluation version, OEMs get everything they need to implement the system in their automotive cabin. The included ADSP-21562-AUTO board is pre-flashed with the board support package firmware image and includes documentation detailing the control API and example scripts. OEMs can then easily test and tune the system using AWE Tune software without the need for software integration expertise.

By implementing this evaluation package, OEMs have all the tools to easily customize and implement a high quality entertainment system in their cabin. The only limitation of the evaluation version is that the audio will have a distinctive tone after 1 hour of operation.

After OEMs have evaluated the package's features and tuned the system to their needs, they can negotiate a license agreement with Analog Devices to obtain production software with no audio artifacts. This solution allows OEMs to save on research and development costs associated with in-house development of entertainment systems and provides a high-quality audio signal flow that differentiates them from the competition. The production version includes all hardware files, allowing OEMs to continue production with minimal cost and effort. Additionally, for OEMs with specific needs, Analog Devices also offers customized design and board support package options.
