Hi, Shai,

That is interesting, I decided to research it a bit and there is a 2016
thread on Gearslutz started by Jeff Willens

<https://www.gearslutz.com/board/music-computers/1086321-do-you-use-rf64.html>

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:
<http://blog.bjornroche.com/2009/11/wave64-vs-rf64-vs-caf.html>
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.

Cheers,

Richard
