Description

This codec is the latest upgrade to the MPEGAAC family. It improves significantly the audio quality of musicand speech particularly at very low bit rates of 8 kbit/s and more,and is compatible with HE-AAC streams. This demo is streaming RadioHaugaland in Norway at 16 kbit/s.

This demo is made for our broadcast solutions TheRadioHub incorporation with Fraunhofer IIS.

Low bitrate streaming benefits both the radiostation andlistener as lower demand for bandwidth brings cost down andstability up.

TheRadioHub-team can deliver xHE-applications with high qualityat a low price.

Extended HE-AAC combines the advantages of existing speech andmusic codecs. By adding a new set of encoding tools to the HE-AACv2audio codec, Extended HE-AAC outperforms dedicated speech andgeneral audio coding schemes and bridges the gap between bothworlds, providing consistent high quality audio for all signaltypes. As a result, Extended HE-AAC can improve the quality ofexisting low bit rate services or more audio channels can betransmitted at a given bit rate.

ISO MPEG initiated this standardization activity in 2008, when acall for proposals on unified speech and audio coding technologywas issued. In the following years, Fraunhofer IIS was one of thedriving forces in the standardization process. The new AACgeneration is now presented for the first time by Fraunhofer IIS atMobile World Congress.
