New ECNR solution comes integrated in NXP chipsets with ITU-T P100 and CarPlay® pre-certification
EINDHOVEN, The Netherlands, March 27, 2018 (GLOBE NEWSWIRE) -- NXP Semiconductors N.V. (NASDAQ:NXPI), has announced a new echo cancellation noise reduction solution (ECNR) that significantly reduces the problem of noisy voice communications and provides carmakers with a consumer pleasing, hands-free calling experience. The cost-effective solution combines innovative ECNR software that can be easily ported onto NXP i.MX processors and NXP’s leading car radio tuners and DSPs1. The new NXP ECNR solution is also ITU-T P1110 and CarPlay® pre-certified.
Echo and noise can make communication on the road difficult. Echo occurs when the speakers within a car transmit a voice signal from an incoming call, which subsequently ricochets through the vehicle and returns to the microphone. This causes the caller to hear their own voice, which is distracting and can result in broken communications. Additionally, road noise from fans, exhaust, tires, windows and passengers can infiltrate calls and render them unintelligible, ultimately disrupting the driving experience and causing frustration.
The new NXP ECNR solution deals with both problems by removing echoes and filtering out unwanted noise from the cockpit to enhance the sound quality of conversations. Since the ECNR solution can be ported to NXP chipsets and is ITU-T P1110 and CarPlay® pre-certified, it can reduce carmakers’ R&D expenses and speed up the design cycle.
“The NXP ECNR software has been deployed worldwide in more than a billion phones 2 and we want to deliver this leading3 market-proven technology to our automotive customers,” said Alexandre Henon, marketing director of audio solutions at NXP. “We adapted our ECNR to automotive requirements and ported the software on two NXP chipset families to provide NXP customers with an easy to implement, high-performance and architecturally flexible solution depending on where they want to run the ECNR function.”
