There's only some Gain and Peak values in the SV8 header. No more info I =
=3D
can
find.

You can do scaling wherever you like as long as it's after the =3D
non-linear
part (quantisation). I guess that using DRC on a lossless file, would =3D
simply
not make the decoded copy lossless :). Of course you could always chose =3D
not
to use the DRC and still keep it lossless.
