New release of QNX acoustic processing suite means less noise, less tuning for hands-free systems

Paul Leroux
This just in: QNX has released version 2.0 of its acoustic processing suite, a modular software library designed to maximize the quality and clarity of automotive hands-free systems.

The suite, used by 18 automakers on over 100 vehicle platforms, provides modules for both the receive side and the send side of hands-free calls. The modules include acoustic echo cancellation, noise reduction, wind blocking, dynamic parametric equalization, bandwidth extension, high frequency encoding, and many others. Together, they enable high-quality voice communication, even in a noisy automotive interior.

Highlights of version 2.0 include:

Enhanced noise reduction — Minimizes audio distortions and significantly improves call clarity. Can also reconstruct speech masked by low-frequency road and engine noise.

Automatic delay calculation and compensation — Eliminates almost all product tuning, enabling automakers to save significant deployment time and expense.

Off-Axis noise rejection — Rejects sound not directly in front of a microphone or speaker, allowing dual-microphone solutions to hone in on the person speaking for greater intelligibility.

The QNX Aviage Acoustic Processing Suite can run on the general purpose processor,
saving the cost of a DSP.
