Digital Audio Compression (AC-3, E-AC3) document A/52 specifies information on
the audio information coding and decoding process. The coded representation specified
is suitable for use in digital audio transmission and storage applications, and may convey
from one to five full bandwidth audio channels, along with a low-frequency enhancement
channel. A wide range of encoded bit rates is supported by this specification. Typical
applications of digital audio compression are in satellite or terrestrial audio broadcasting,
delivery of audio over metallic or optical cables, and storage of audio on magnetic, optical,
semiconductor, or other storage media
