Since the audio we hear consists of analog waveforms, not ones and zeroes, the first step in the process of creating a Dolby Digital audio track is to convert the original analog signal into digital information. Encoding and decodingĭolby Digital operates in a world of ones and zeroes - digital information. This expands the creative palette for artists, and allows those of us in the audience to experience greater realism and excitement. With Dolby Digital, it's possible to include a full 5.1-channel audio mix on a film print or a DVD, or as part of a TV broadcast. The smaller the file, the easier it is to distribute.
At its core, Dolby Digital technology represents a very efficient way for movie studios, television networks, and other content providers to compress the size of multichannel audio files without impairing the sound quality.
