Hmm, I thought FLAC only did 24-bit???
I think the
FLAC spec says it will handle anything from 4-32
bit-depth:
https://xiph.org/flac/faq.html#general__samples
That said, Audacity only has FLAC export options of 16 & 24 bit
depths. Ardour supports 8, 16 and 24. Still no 32 bit float support
(at application level).
I should correct my previous statement though: I *thought* I exported
32bit float: but it turns out they're 24bits (from Ardour3),
dithering set to None. And cropping the resulting output in Audacity
and exporting was to 16-bit PCM, so I was actually doing this all
wrong (no dithering, 32 -> 24 -> 16).
A better workflow would be to:
A) Ardour export 32 bit float -> 16bit (with dither) -> Audacity
16bit in, crop, 16bit out
B) Ardour export 32 bit -> 24 bit (no dither) -> Audacity 24bit in,
crop, export 16bit (with dither).
The important part being to not dither twice, since then you'll be
adding noise to the signal twice!
I'll be using option A above from now on I think, since it involves
less bit-depth changes.

One of FLACs competitors does 32bit float since many years: wavpack.
I'm not quite sure why it is much less popular than FLAC.
