32 Bit Float files... How do you archive them?

can this do flac?  playing around with it and it compressed to .wv with no option for flac.  googling and reading up now but haven't found anything yet.

Easy enough to just convert to .wv though.  I tested by converting a 32bf stereo file and then converted back to wav.  audio properties are identical!  now to test a poly wav...

edit:  works perfect on poly wav as well!

I know, I'm late to this party as well, but I just ran into this again recently, and as this thread popped up in an unrelated search, I figured I'd see if I could learn something here.

Ever since the 32-craze took hold, it's been a little confusing to me - and a few others, it seems.
My lathe-cutting studio is pretty lo-fi / old school, and I'm a few years older than I used to be, and fumbling through a ton of "floating point" discussions everywhere I go these days, hasn't cleared up anything for me. At best, it sounds like something I probably don't need?

I forget how far back it was, but at some point, certain apps simply started identifying whatever I put into them as 32 bit floating point.

On both my Mac and PC, the last install I did for VLC has gone the 32-bit route, so if I'm hoping to identify the file, all it's going to clarify is the Sample Rate (44100, 48 or 96kHz). Bits Per Sample always comes up as 32.

For the purposes of trying to identify what the files are, so I can save them as .flac files, I've been trying several methods, with varied results.

On the PC, both Sound Forge and CDWave will call out the bitrate as either 16 or 24 bits - well, at least if I'm the one who recorded the files, or the person I got them from identified them as such. Also on the PC, if I try to find out what the file is in Traders Little Helper, the "Show Audio File Details" feature rejects them with an "unsupported format" error message. Even looking up Properties in Foobar just tells me that Bits Per Sample : 32.

On the Mac, however, XLD is what I use for tagging files, etc. Trying to even open a 32-bit file in XLD results in an error message: Selected output format does not support input format. So it seems that I do need to be able to convert into something XLD can recognize and work with, which is the main reason I'd like to identify all these 32-bit files in the first place. 9 out 10 times, if I ask the person who sent me the files, they won't have a clue, and if I try to explain any of this to them, they genuinely seem to have no idea what I'm talking about. I don't know why this is the situation, but it is what it is, I guess.

Well, I *hope* I'm not resurrecting this thread for nothing, or that I'm not off-topic, so I don't get scolded or whatever, but if I'm ion more or less the right place, and someone else may have figured out a method of just being able identify 32-float files as what they really might be in terms of bitrate, that could help with the occasional filesets that some to me that way. I suppose it's *possible* that whoever sends me these types of files may have things set that way, but if that were the case, than it seems they would know what I'm talking about when I try to sort it out with them.

Thanks in advance for any help - if there is any!

I just tried this again and my flac is a 24bit file!  I tried output bit depth on auto and on 32bit.  Dither is set to never.  Both settings resulted in a 24bit file from my original 32bit float.

Once imported, Audacity seems to display all files at the selected bit depth setting, chosen via Audacity > Preferences > Quality > Default Sample Format
