I read a post from another site reporting the above tool as a good converter for the file format, I did not bother going for it as I have dbpoweramp on my machine so I was initially looking for some codec that can recognize the file format and convert it to my usual ones. I did not think of DFF to DSD but DFF to 192khz/24-bit Flac.
Using Korg Audiogate. No ptoblem changing from dff to dsf or 24/192 flac.
May give that a try, thanks!
Google dbpoweramp DFF codec and you should be able to get the link, just remember, it is labelled as a beta codec.
Found it, thanks!
