This is true, but as Folderol wrote, 32 bits should be *plenty* of
dynamic range for audio. In fact, it has been argued that ~22bits is
sufficient as beyond this you get into the h/w noise floor, hearing
limits, etc.
24 bit means 135dB signal/noise ratio.
I haven't seen yet analog gear capable of 135dB. Hints:
- 90dB is the difference between a jackhammer and silence
- the human hearing range is 120dB - above that permanent injury occurs
- the space shuttle taking off generates "noise" somewhere in the 130..140db
Note: yeah, I know, rigorously speaking I'm mixing here several
different scales that should not be mixed. Don't kick the messenger into
the pit, even if "this is Sparta". ;-)
(bonus points for figuring out the reference)
