Iosono Surround Sound – a perfect companion to 3D releases?

Having been programmed with the actual dimensions of the replay space, and number of available playback sources, the Iosono decoder outputs audio signals tailored for the installation-specific loudspeaker channels. The result has been described as an ‘acoustic hologram.’

‘While it is possible to create a fairly realistic sense of acoustic space with conventional surround-sound technology,’ concedes Brian Slack, Iosono’s SVP of Studio Technologies, ‘there is one major drawback – the mix requires that the listener sits in the so-called ‘sweet spot.’ Outside of that, any sound will be perceived to originate only from a very general direction.’

‘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).

Iosono Surround Sound – a perfect companion to 3D releases?


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.

Dolby Digital premiered in 1992 with Batman Returns, while DTS launched a year later with Jurassic Park
