Bringing Noisefree to Handsfree: New Release of QNX Middleware Boosts Quality of In-Car Phone Conversations

QNX Software Systems today announced a new release of the QNX(R) Aviage(R) acoustic processing kit, an innovative software product that dramatically reduces the cost and improves the quality of handsfree systems for the automobile.

Built on proven technology deployed in more than 60 vehicle platforms from Audi, BMW, Chrysler, Fiat, GM, Honda, Hyundai, Mercedes-Benz, and other automakers, the QNX Aviage acoustic processing kit replaces dedicated voice- processing hardware with a small, efficient software solution. The kit uses patented algorithms to extract the human voice from noisy car interiors, thereby improving the clarity and user experience of handsfree phone conversations.

The new release of the QNX Aviage acoustic processing kit introduces several new capabilities, including: automatic gain control to maximize the dynamic range of incoming audio; a parametric equalizer for precise control over in-car sound quality; dynamic level control for automatically raising volume levels during periods of high cabin noise; a limiter/compressor to provide consistent speech level; a bandwidth extension feature for fuller- sounding conversations; and an enhanced diagnostics module to simplify system integration issues.

With other solutions, it often takes a week or more to tune noise suppression and echo cancellation for a specific vehicle. With the new QNX Aviage kit, the tuning process typically takes less than half a day. To make system optimization even easier, the new release includes a Windows-based, remote-control utility that lets developers interactively turn features on or off, tweak settings, adjust performance, start and stop streaming audio, restart and reset the library, log events, and run diagnostics -- all while a handsfree call is in progress.

Highly customizable, the QNX Aviage acoustic processing kit offers a modular library of software algorithms that system designers can use individually or in combination, based on application requirements. This modular architecture, along with support for multiple processors and DSPs, allows system designers to easily update, modify, and reuse the kit across multiple product lines. As a result, customers can maximize investments in development and further reduce production costs.

"Handsfree systems are the key to improving the interaction between the driver and in-car electronics, and the new release of the QNX Aviage acoustic processing kit introduces several features that make handsfree conversations more intelligible and enjoyable," said Andrew Poliak, worldwide automotive sales director at QNX Software Systems. "Just as important, the kit makes handsfree systems affordable for a much larger range of automobiles, including economy models."

Availability and hardware support

The QNX Aviage acoustic processing kit v1.2 is slated for release June 27. The kit runs on a variety of 32-bit CPUs and DSPs, including ARM9+, SH-4+, PowerPC processors, and TI C64x DSPs.
