Hmm are you sure 5mm is audio?

This article claims Audio is added via USB Stick or CD

I was referring to regular 70mm, in which 65mm is for the picture and 5mm is to allow for the sound channels. I am not surprised - squeezing even more out of the film, that IMAX would just put audio separately.

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
