Description

16-bit PCM will continue to play its role of standard digital storage medium as it did since the advent of Compact Disc, but the entire digital technology movement is directing toward higher-efficiency coding as found in some of recent applications. Defined as emission coder based on TDAC transform. Dolby AC-3 employs a filter bank with critical band principle derived from human auditory model, overlapping windowing for improved block-to-block continuity, and furthermore by processing 5-channel audio data as an entity, its performance is exceptional for a given bit-rate unlike multiplying independent channel coders. This paper also discusses necessary infra-structural establishment for multi-channel programs.
