Not exactly - Zoom stuff does a clever trick of using 2 ADCs at different gain levels (essentially the same way that HDR photography works), but ultimately it's still using fixed-point ADCs.

This isn't actually a new idea - I know Line 6 has been using it in guitar pedals since at least 2006. Of course, ADCs have gotten better since then - I doubt they were getting even 24 ENOB back then.

Ah the F6 has dual ADC and it uses that to cover a larger recording range - best explained here https://www.youtube.com/watch?v=NTuJ1fk3PsY

Also nicely explained by Sound Devices here for their offerings: https://www.sounddevices.com/how-is-a-32-bit-float-file-reco...

Still pondering the F2, does it have dual ADC to capture that input range or is this why they sell it with a lavier mic included (hmmm).
