Something that I've always wanted to have and this dude made it!
to your main comp audio track and then it's linked in all the others, its pretty smart cus it takes time remapping into consideration and corrects
Ok, so here's my process.
~precomp the audio track (I usually name it something like Master Soundtrack)
~Now drop that fancy new audio precomp into an existing precomp in your timeline.
~Apply a "time-remap" to that audio precomp
~Alt click the stopwatch, paste the expression above.
~Change "Master" to the exact name of your main composition.
~Right click the audio precomp and set it as a guide layer (This step isn't necessary, just nice to not have multiple layers of sound in the main timeline)
The audio will line up exactly no matter where you move the precomp in your main timeline.
Sounds like a lot, but once you do it a few times it will feel easy. Aaaaand no more bouncing in and out of comps to find that audio cue.
An issue I've had is that it only seems to work one pre-comp deep from the master composition. There's probably an easy solution to that, but haven't really dug into it enough.
Hope that helps!
This looks awesome- where do you apply this expression to?
Looks like a nice replacement for the expression I always use:
MasterC = "Master";
PreC = thisComp.name;
C = comp(MasterC);
L = C.layer(PreC);
Main_T = time + L.startTime;
Its called Universal Audio
