Every major DAW already does this- 32 bit float is standard for internal processing, and quite a few of them support import/export of 32 bit files as well. Some even work at 64 bit precision internally (Studio One and Reaper both come to mind).

Sadly, I think that mine (FL Studio) doesn't, or at least it doesn't between channels when mixing into channels. It definitely goes above clip, but horrible things are be to expected when mixing it with other channels.

I assumed it was the norm as FL Studio is gaining immense amounts of traction with the more recent updates to advanced competence. I might have been wrong in that assertion.

Either way, my DAW does not represent it in a way that makes sense to a software engineer.

I would certainly love to actually work in HDR, as opposed to it being a ghost in the machine.
