Fraunhofer IIS Premieres Extended HE-AAC

New member of AAC audio codec family enables improved speech and music audio quality

Fraunhofer IIS will premiere Extended HE-AAC, the latest upgrade to the MPEG AAC family next week at the Mobile World Congress.

The codec developer says Extended HE-AAC significantly improves the audio quality of music and speech, particularly at very low bit rates of 8 kbps and more, and is compatible with HE-AAC streams.

As a result, Extended HE-AAC can improve the quality of existing low bitrate services or more audio channels can be transmitted at a given bit rate, according to Fraunhofer.

ISO MPEG initiated this standardization activity in 2008, when a call for proposals on unified speech and audio coding technology was issued. Fraunhofer has been a driver of the standardization process.

The Mobile World Congress is Feb. 27 – March 1 in Barcelona.
