CDR-Info have brought to our attention, news about NEC producing a extension to the current MPEG AAC audio format.

" NEC today announcedd the successful development of a cutting-edge audio coding algorithm as the extension of the current "MPEG AAC (Advanced Audio Coding)" technology.

MPEG-4 AAC is the high-quality general audio coder standardized by ISO. CD-quality sound realised by AAC requires 96Kbps of stereo. NEC's new , MPEG-4 AAC Ext.1 codec has been developed to further decrease bit-rate while maintaining the same audio quality.

The advantage of the new technology is that it realises higher sound quality at lower bit-rates enabling audio services on bandwidth-constrained networks. For example,. 128 kbps of stereo CD quality (MP3) can be encoded into only 48Kbps, an approximate reduction of 50% from MPEG-4 AAC's current requirement of 96Kbps. The new MPEG-4 AAC Ext.1 coding technology also supports high compatibility with current MPEG-4 AAC."

It is always good news when a major manufacturer decides to enhance such a good audio codec, and it will mean better sound at lower quality, helping amongst others, video streaming abilities.
