I remember watching a Steinberg mixing tutorial video years ago where the presenter stated in no uncertain terms that projects should be set to 32bit floating point depth because this allows you to record with lots of headroom left over and also allows you to mix in any way you want and there will be no internal clipping.
Ever since then I’ve mixed every song in 32bit float.
However, I’ve since heard over and over (most recently in The Home Recording Show podcast) that all those same things apply to 24bit recording and that all DAWs internally use 32bit floating point precision for mixing. So that there’s no need to record at 32bit float as it just uses unnecessary disk space.
So what’s the truth? Am I just wasting disk space?
