jam sync - audio from different sources
Hello to all,
Sorry if this is not the right forum but I thought these sync issues may be more common in post.
I have two audio-only recordings from the same concert - the one that was made by the theater crew (3 mics/channels, protools system, "hall" sound); and the other I did with the stage spots (sound devices, spots mixed as LR, dry/very 'spoty'). Both systems recorded at 24-44 - but no sync at all and not same start/end times.
I received all files and decided to put everything together to get a better sound. I did time align the files - visually and by ear - the best I could, so the sound 'glues' and files start together ('hall' a bit later, as it's 'hall' sound).
But the thing is: the first music piece is around 9 minutes, it 'starts' synced as I put, but near the end the sync gets jammed, and spots are late than 'hall' ?!?!
My question - is this common? Am I doing anything wrong or getting crazy?
In the second piece (ca. 27min) it gets even worse as there was a 'tape' recording playing along with the live sources + P.A. ... I have the tape itself, but sync gets even trickier with more sources and worse as time passes... delays... delaays... deeeelaaaaayssssss !
Is there a better way to sync these files?
Thanks for any help.
all the best,
