I am also referring to regular 70mm, not IMAX, so is that part of the article.

> 70mm film uses DTS audio, which is supplied to the cinema on either CD-ROMs, or (more recently) via USB sticks.

I have never seen that in real life though, only regular 70 mm film of which 65 mm is definitely used for the picture and audio channels for the rest. E.g Lawrence of Arabia
