I've been doing AUD/SBD recording using two recorders - then combining them in post.
(BTW - Im using two clock synced A>Ds - so Im not fighting any drift issues...)
I like the results - however, Im afraid the post production time is going to make this approach prohibitive.
I cant justify screwing around for 3 hours on post show work. And too often, Im noticing things that I want to go back and tweek after Im "done"
Not every show requires this much attention - Some go together a little easier...
But from a hobbyist perspective - this is too much time...
My on the fly efforts seem to be just as good when it comes to the final product...
All this - and Im still working in 16/44...going to 24 bits means bigger files, more data, and longer processing time...
Im thinking of abandoning this approach for now...
Anyone else getting bogged down by 4 track post work?

Edit:
Heres a good on the fly effort
