摘要：

A new low bitrate audio coding technology (further denoted as "ExAC") based on Enhanced Audio Coding (EAC) and Spectral Band Replication (SBR) is introduced. The major building blocks of the coding schemes are explained, in which EAC works as a core coder and SBR works as a powerful bandwidth extension module. The new coding technology provides a high quality audio compression scheme for a broad range of applications, including the high-density laser video diskette, HDTV and very low bitrate applications such as AM audio broadcasting and streaming.
