to the bold, i would hope so, but idk if audacity does.

Not sure how much dithering when truncating to 24bit actually matters if the noise floor of the recording is well above the 24 bit truncation depth.  Whatever the noise floor, normalizing raises it by the same amount as it raises the signal, so there should remain plenty of dynamic range room available for both.

Similar conversation going on presently on page 2 of this thread- 48 KHz vs 44.1 KHz sample rate

When I use Audacity, I have it set to NOT copy files into the project directory. I point my Audacity sessions to the relevant file inside my "Digital-Audio-Originals-FOLDER"
Saving the Audacity projects does't require much drive space, unless there are processed versions stored.



If I were recording lots of channels in polywav, I would consider naming the tracks in the recorder so that the polywav had tracks named for their sources.
I believe this can all be typed in to a SD mixpre by using a mobile device, paired via bluetooth using the Wingman app.

I do that with the F8, and get a little smile when I glance at the meters.

This blew my mind...I didn't know it's possible.  I'll have to dig into the F8 manual to investigate.   :o

I use Foobar2000 to convert my 32fp/48k WAVs to FLAC.  Never an issue.

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.

Wavpack.That can handle floating point wavs.

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!
