That is interesting, I decided to research it a bit and there is a 2016
thread on Gearslutz started by Jeff Willens
Someone named Michal provided some excellent discussion surrounding the
RF64-W64-CAF question. The one thing that needs to be updated is that
iZotope RX handles RF64 files -- at least I tried a 3 GB one from 2011
and it opened now. I was also able to open a 10 GB multichannel WAV in
iZotope, though track mapping has been a bit of a challenge in that
interface--it's more designed for surround processes.
That thread points to a blogger essay by Bjorg from 2009:
that might be of interest.
This is not a new issue, actually.
I think, in general, since the standardization of RF64 by EBU it makes
more sense to use RF64 which, I believe, comes under the BWF umbrella.
In my world, if RME, iZotope, and Samplitude support RF64, I am happy.
