With this technology, conference calls will be easy to follow and much less exhausting, phone calls in noisy environments will be easier to understand, and being on hold will sound as if listening to a concert on an mp3 player.
The Fraunhofer Audio Communication Engine combines several elements that may be incorporated in future 4G handsets. First, the specifically designed MPEG audio communications codec "AAC Enhanced Low Delay" ensures CD quality audio at very low coding delays and bit rates. Second, multi-channel echo control software removes echoes, providing hands-free convenience and complete freedom to move around in a room. Finally, a specially matched IP streaming stack and error concealment tools allow for high-quality audio even under adverse network conditions.
