A New Parametric Stereo and Multichannel Extension for MPEG-4 Enhanced Low Delay AAC (AAC-ELD)
ISO/MPEG standardizes two communication codecs with low delay: AAC-LD is a well established low delay codec for high quality communication applications such as video conferencing, tele-presence and Voice over IP. Its successor AAC-ELD offers enhanced bit rate efficiency being an ideal solution for broadcast audio gateway codecs. Many existing and upcoming communication applications benefit from the transmission of stereo or multi channel signals at low bit rates. With Low Delay MPEG Surround, ISO has recently standardized a low delay parametric extension for AAC-LD and AAC-ELD. It is based on MPEG Surround technology with specific adaption for low delay operation. This extension comes along with a signicantly improved coding efficiency for transmission of stereo and multi channel signals.
