Digital SoundĪll sound that you hear during a Digital Cinema presentation is stored and delivered digitally, as mentioned previously. Think of film-based digital sound being similar to an MP3 file and digital cinema sound being like a multi-channel CD. The sound is compressed losslessly, which means that there is no compression used that removes any of the original sound that was produced in the studio. All Digital Cinema Projection systems output sound digitally, whether it is one channel or up to 12 channels that is allowed by the Digital Cinema specification. The movie theater industry is transitioning itself to using Digital Cinema Projection systems, which means that film has been replaced by digital files provided by a computerized server.
