You way should have worked, too. There is a 24/48 option under "other".
sorry for replying to a subject 3 yrs old but it might be possible another soul like me stumbles here while searching for an answer...
The funny thing is, the only way
to get a 24-bit file out off Audacity 2.1.2 in fact seems to be via "Other uncompressed files" when saving/exporting;
because no matter
what settings you had been chosing in "Options" already - will be ignored
again when you want to export/save the finished file.
Another thing - if you then chose the "WAVE (Microsoft)" data format (which it's set to by default anyway) - what you will get is an AIFF-file instead. (?)
Is this a(nother) bug, or didn't i just find a somewhat hidden check box to avoid this very strange behavior?
So, getting a 24-bit WAV file directly, for example, at the moment is not possible... am i right or wrong?
Thanks a lot for any helping reply,
