Overview

Modern cars contain multiple acoustic and audio signal-processing systems (handling the many microphones and speakers, music, noise and echo cancellation, in car communication etc.) all running simultaneously. These systems often interact with each other in unpredictable ways, unless great care is taken to make each subsystem aware of the others. QNX Acoustics Management Platform (QNX AMP) eliminates this integration headache by offering a unified approach to managing acoustics in the car, allowing subsystems to work together harmoniously. To further reduce software integration efforts, QNX AMP comes pre-configured with built-in audio-signal routing.

Leveraging the power of the QNX Neutrino® Realtime OS, QNX AMP uses a low-latency audio architecture that offers real-time, high-performance signal processing on general-purpose application processors – with unprecedented time resolution as low as one millisecond. As a result, automakers, at their choice, can eliminate proprietary digital signal processing (DSP) cores or specialized external hardware to implement compute-intensive acoustics applications, thereby reducing significant cost of the audio system.
