If one need to use a compiler that only you have, I'd say that your

It was your claim that sound could be edited in hex form. If that is
true, then anything else can be similarly "edited" in hex form.

Nowhere in the GFDL does it say that it is OK for a transparent format
to make only certain kinds of changes possible.

And if you want to change the words of a poem read alouf, I don't
think you're going to be able to do that if I give you a hexdump of
a PCM file.

My point is exactly that *no* way of editing sound files will allow me
to do the kind of changes we normally require for freedom.

Yes, but it's possible in principle.

No, they are not possible in principle.

Exactly. Therefore, sound is opaque no matter what format it is in.

The "thwart modifications" language in the GFDL applies only to
unconventional uses of otherwise transparent formats. The definition
of transparency is;

I maintain that this effectively excludes any conceivable sound

I *cannot* distribute a transparent copy of my spoken performance,
because no such copy is possible, as argued above.
