The new solution comes integrated into NXP chipsets with ITU-T P100 and CarPlay pre-certification
NXP Semiconductors has announced a new echo cancellation noise reduction solution (ECNR) that it claims will significantly reduce the problem of noisy voice communications and provide 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 DSPs. The new NXP ECNR solution is also ITU-T P1110 and CarPlay pre-certified.
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 of the above 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 and we want to deliver this leading market-proven technology to our automotive customers,” said Alexandre Henon, marketing director of audio solutions at NXP.
