But I've found f32 to be incredibly useful because it allows me to very spontaneously capture unexpected sounds with little to no setup or preparation. In fact, sometimes I even forego monitoring in favor of just quickly getting out the recorder and microphones and then hitting record -- since I don't have to fiddle with gain, I know that I can capture something usable rather than missing the opportunity altogether.
When I have time to prepare a recording and it's not going to have a crazy amount of dynamic range, then sure, f32 isn't a make-or-break feature, and needing to do post-processing 100% of the time before the audio is usable in non-f32 contexts could be seen as a drawback. But for my use cases, absolutely useful and worthwhile.
I suppose they use different gains per DAC and map that to the respective dynamic ranges of the f32 signal?
