Not sure about that kind of process being cross platform in all DAWs...
So, there is a bundle file format, but Logic will not open it.
So..as they do in video land with the snap board and sound of it......mark each track with a Loud marker sound at each beginning or end point...set loop markers of song length....export stems, or tracks to individual formats needed by the other collaborator , and he or she will have to align the markers in the right format and import in to the right bit depth, time signature, and tempo, you have set in your project put on a note pad or in the stem names...all this info can be put on a note pad for that to go forward...
And then they can cut out the silence and such...it should all line up, if the export settings between "loop marker" is set or selected in the export feature window , before doing the actual export...and or the file type wanted to be individual track per track exported into.
All tracks will then all be the same size...so should be no re alignment necessary...but put the markers of sound on all tracks at the exact same places...just to be sure?
Any other way?...Not that I am ware of.
Cheers.
