There's a problem with f32 due to devices using two ADCs to implement it. Essentially, there's certain volume threshold when device switches DACs, and it's audible. If you record sources with varying loudness, you may see noise floor raising around loud bursts, and typical noise suppression tools won't work on files like this (there was a video or a blog post, I can't recall where I saw this). At least this is how Zoom implemented f32, don't know about Sound Devices.
