At IFA in Berlin, Fraunhofer presented its Enhanced Low Delay AAC codec (AAC-ELD) as the “next generation” video telephony solution for SmartTVs.
Demonstrations were put on at a Fraunhofer booth to demonstrate improvements in audio quality using AAC-ELD for SmartTV communications apps. Billed as “Full-HD Voice",” AAC-ELD supports audio bandwidth of more than 14 kHz (as compared to 3.4 kHz on a PSTN-grade voice call).
AAC-ELD is supported in both Apple iOS and later versions of the Android operating system. Fraunhofer hopes to see the codec continue to proliferate and be applied to both audio and video communications solutions.
