I don't have any special knowledge of the actual implementation of these in=

But if that conversion were to floating point rather than fixed point data,=

At least that's the guidance that's being put out by the DAW makers who are=
 using 32 bit floating point mix engines, some of which now can store files=
 as 32 bit floating point as well.
