The only reason I can see for being not bothered and making do with 44.1 16bit is the storage size.
Wavepack as show below @48khz/24bit is smaller than your current 44.1khz/16bit files.
If you are saying that wavepack is a non standard format that's irrelevant as it's only Biab that is opening it, and Biab renders to wav wma m4a mp3.
It's like saying kontakt should not use it's non standard formats.
I can import wavepack into more DAW's than wma. Adobe Audio used wma but I had to get Reaper to implement it.
I can understand that you would have to do some programming for Biab to read wavepack and that may be the reason for not being bothered.
So a Wavepack 48khz/24bit Audiophile edition would be smaller than the current wav edition.
I have seen you arguing like crazy that a 64bit version is not needed as JBridge works fine, this went on for ages with masses of users wanting the 64bit version, but no, it's the same reasoning. It's not a baffling mystery why Biab has been so far behind is it ?
The needs of the many outweigh the needs of the few.
Honestly if I couldn't be bothered back in 2009 and just left here and gave up what would you have now and where would you be, there are just so many features and function you have now in Biab to make things so much easy for users than what I had at the time. All this has taken me a hell of a lot of time and work posting videos, pics, examples of things actually working.
Just don't take it all that for granted, give me some respect, just don't ignore and blow it off as nothing important.
