QNX Acoustics Management Platform

A breakthrough in acoustics for vehicles.

A Fully Integrated Software Architecture to Manage Vehicle Acoustics

The QNX® Acoustics Management Platform (AMP) 3.0 is a breakthrough in automotive software. For the first time, automakers can design and manage the total sonic experience in their cars with a pure software solution designed to run on general-purpose application processor cores–saving bill-of-material costs and cutting time to production while delivering new features and uncompromising sound quality.

Automotive acoustic and audio signal-processing features need to operate simultaneously while sharing microphones and loudspeakers in the vehicle cabin. QNX AMP comes pre-configured with a core set of audio and acoustic functionality and extensibility that meet the requirements of advanced system designs—now, and in the future.

Product Brief

A Pre-Configured, Extensible Solution for Building Cost-Effective Acoustics Systems

Low-Latency Audio Signal Processing

QNX AMP uses a low-latency audio architecture that offers real-time, high-performance signal processing on general-purpose application processors–with time resolution as low as one millisecond. Automakers can eliminate proprietary digital signal processing (DSP) cores or specialized external hardware to implement compute-intensive acoustics applications.

Integrated Solution

QNX AMP offers unified management of all car acoustics, enabling automakers to reduce the cost, complexity and time-to-production of audio signal-processing systems. It also offers flexible options, allowing the use of only the functional modules as demanded by the needs of the system, and deploying them in native QNX, native Linux® or directly in a digital signal processor (DSP).

Seamless Integration with Guest OSs

QNX AMP can be implemented in a virtualized environment using QNX® Hypervisor. This allows seamless integration with Linux and Android™ infotainment guest OSs with full support for all audio functionality.

Powerful Tuning, Analysis and Diagnostic Tools

Powerful Tuning, Analysis and Diagnostic Tools

The QNX LiveAMP tool supports diagnostics required for HEAD Acoustics testing. And LiveAMP enables rapid tuning of parameters to optimize performance to a specific vehicle configuration, with many steps completely automated.

BlackBerry QNX also offers training, tuning, testing and compliance certification.

QNX Acoustics for Voice

QNX® Acoustics for Voice is an advanced, modular library of field-proven algorithms designed to detect and isolate voice from cabin noise including sounds caused by road surfaces, construction, engines, wind, rain and other vehicles. It dramatically improves the clarity, quality and accuracy of in-car communication and speech recognition systems, setting a new benchmark in hands-free quality. QNX Acoustics for Voice supports rigorous requirements for smartphone connectivity including Apple CarPlay® and Android Auto™. Support for WakeWord and Virtual Assistants is also available.

QNX In-Car Communications

QNX® In-Car Communications (ICC) enables safer conversations. Instead of shouting or turning around to be heard, drivers can talk normally to passengers while keeping their eyes on the road. Multiple capture and playback zones allow front-to-back, back-to-front and passenger-to-passenger communication. QNX ICC dynamically adapts to noise conditions and adds enhancement only when needed.

QNX Active Sound Design

QNX® Active Sound Design (ASD) offers a complete vehicle sound design and active noise control solution that allows sound designers to control the desired ambient noise from both within the vehicle and outside the vehicle (Acoustic Vehicle Alerting Systems supported). QNX ASD includes a suite of software components that reduces unwanted cabin noise, enhances and creates new engine sounds and projects sounds to pedestrians. Sound components can be pre-tuned and pre-calibrated in real-time using QNX LiveAMP.

QNX Software Audio Management

QNX® Software Audio Management (QNX SAM) delivers a comprehensive loudspeaker management, media playback and sound field optimization solution built entirely in software, reducing and eliminating the need for external DSPs. It enables high resolution of media playback streams on the main application or infotainment CPU. The audio system architecture is specified via software configuration and can scale from a base-level audio system with four loudspeakers to a high-end audio system with twenty or more loudspeakers.

QNX Chimes and Safety Alerts

As more ADAS and autonomous features are deployed, monitoring of the playback signal is essential for when drivers are required to attend to a situation and take over control. QNX® Chimes and Safety Alerts (QNX CSA) enables the monitoring of chimes and safety alerts using one or more in-cabin microphones and one or more chime reference signals. Because the solution is software-based, automakers can eliminate dedicated ECU hardware.

QNX LiveAMP

QNX® LiveAMP is a PC-based graphical tool for tuning, diagnosis, configuration and analysis of the QNX AMP. QNX LiveAMP is beneficial for real-time and interactive adjustments of all system parameters, injection and streaming of signals and vehicle data at multiple tap-points in the system, tuning automation using QNX CHATS, monitoring using device-under-test and/or reference microphones, real-time spectral displays, configuration file management and offline sound design for QNX ASD.
