QNX® Acoustics for Engine Sound Enhancement provides a comprehensive tool and runtime library to help automakers and tier 1s create or maintain signature engine sounds and enhance the appeal of their vehicles. The technology helps enhance naturally transmitted engine sounds by playing synthesized sounds synchronized to the vehicle's realtime data, including RPM and engine load, over the vehicle's speakers.
The QNX Acoustics for Engine Sound Enhancement runtime library integrates into a vehicle's infotainment system or audio system DSP to play back synthesized engine sounds synchronized to the realtime vehicle data.
As more advanced technologies are being employed to improve fuel economy, the sound character inside the vehicle is changing. For example, an engine that deactivates 3 of its 6 cylinders to reduce fuel consumption sounds noticeably different from when it's operating on all 6 cylinders. A gasoline-electric hybrid vehicle sounds different depending on which engine is operating.
