Brief Introduction on ACC

Advanced Audio Coding, or AAC, is a MPEG (Motion Pictures Experts Group) audio standard first adopted as part of the MPEG-2 family of standards. Like its predecessor, MP3, AAC is a Lossy Compression format capable of delivering relatively high quality at relatively low bitrates. There are actually two AAC specifications. In addition to the MPEG-2 version of AAC, which was also referred to early on as NBC for Non Backwards Compatible, there’s a newer specification developed for MPEG-4. This version is normally found in the MP4 Container, either with or without accompanying video.
