Dolby AC-3 is a flexible audio data compression technology capable of encoding a range of audio channel formats into a low-rate bit stream. Channel formats range from monophonic to 5.1 channels and may include a number of associated audio services. Based on a transform filter bank and psychoacoustics, AC-3 includes the novel features of transmission of a variable frequency resolution spectral envelope and hybrid backward/forward adaptive bit allocation.
