The present document specifies a coded representation of audio information, and specifies the decoding process. Informative information on the encoding process is included. The coded representation specified herein is suitable for use in digital audio transmission and storage applications. The coded representation may convey from 1 to 5 full bandwidth audio channels, along with a low frequency enhancement channel. A wide range of encoded bit-rates is supported by the present document. A short form designation of the audio coding algorithm specified in the body of the present document (whether or not annex D is included) is AC-3. The short form designation of the audio coding algorithm specified in annex E is E-AC-3.
