‘Our primary rerecording format remains 5.1-channel soundtracks,’ considers ‘Doc’ Goldstein, VP of post-production engineering at Universal Studios Sound. ‘But we can accommodate other multichannel formats and always have our eye on the future requirements of filmmakers.’ The ubiquitous 5.1-channel format involves three screen channels (left, centre, right) plus separate surround channels beside and behind the audience (labelled left-surround and right-surround) in addition to a low-frequency extension/LFE channel that carries reduced-bandwidth material (hence the ‘0.1’ label).
Such material is carried to audiences on analogue film using one of three data-compressed formats: Dolby Digital, which optically prints the digitised audio between the sprocket holes; DTS, which uses a time code track on the film to synchronise a companion CD-ROM that carries the multichannel audio; and SDDS – Sony Dynamic Digital Sound – which uses a similar technique to Dolby but, as we shall see, can accommodate additional screen channels.
