Is there a way to use audio track from one comp like some kind of the template for rest of the comps? Let me give you an example. I'm working with voice over which i have in main comp and suddenly I decide to sync it to animations or live action in other comp. How can I use it from main comp to other comps in order to maintain in exactly the same place?
I'm not sure that I've understood exactly what you want to do but in general you should be able to put the audio in its own composition where you can edit it and then place that composition in any comp where you need that edited audio.
