4G Phone Calls: Clear As MP3

Phone calls on your mobile 4G phone could sound as clear as an MP3 or CD.

At the Mobile World Congress the inventor of the MP3 format, Fraunhofer, will demo 4G phone calls in stereo CD quality over a 4G cell network. As well as improving the quality of phone call audio, the innovation could bring a welcome quality boost to audio and video streaming services that phone operators offer.

Fraunhofer says its new AAC Enhanced Low Delay codec gives CD quality audio with very low coding delays and bit rates. It’s said to even perform well under adverse network conditions.

Such a boost in phone call quality could make mobile conference calls much easier to understand and less painful to attend. But then maybe there’s no technology that can do that…
