Recently, the question arose as to whether Diamond Cut Audio Software would ultimately ever support 32 bit floating point audio data formats. The answer is no and here is why:
In non-floating point format (fixed - integer) that would represent 192 dB of dynamic range. Referenced to 0 dB SPL and the point of pain in my sound-lab and at 1 kHz, I can not hear anything lower in level than - 70 dB, and my hearing is considered to be very good. Further, no audio system is capable of recording or reproducing that degree of bit depth (resolution).
So, I doubt that we would ever support such a format as it is of no value, especially when one looks at the physics of the thermal noise floor of op amp input stage transistors (about -80 dB). So, it would not be possible to create such an A/D or D/A capable of producing such a result (unless perhaps cryogenic techniques are used for all of the components in the sound system).
As Rick pointed out to me, if this is done in 32 Bit Floating point, the dynamic range would actually be 1,500 dB.

ps - anyone claiming to be capable of recording that does not understand the physics or mathematics of such a claim. I would call it "the latest in Marketing Technology" - - - nothing more than that.
