Can you post some examples of the impact on compression ratio? Do the
samples actually use all of the 32 bits? I have no experince with
this.

If compression of 16-bit audio was limited to 16-bit residuals, I
suspect that would have a significant impact, so I'm wondering how it
is different with 32-bit audio.
