The improved compression efficiency of MPEG-2 Advanced Audio Coding (AAC), the most recent MPEG standard for digital audio coding, now allows the transmission of high quality audio stereo-signals over a single ISDN B-channel. The paper describes the advanced features of MPEG-2 AAC and gives an overview about he practical aspects of the main coding parameters, especially for the case of the single ISDN B-channel application and the resulting audio quality.
