Right.

This assumes that such a thing is possible. In this simplified description
of the problem, setting the actual range might seem easy. In the real
world, as I understand it [*], getting a specific range [**] is very hard.

[*] I've read books on the topic, and DSP is *still* black magic as far as
I'm concerned.

[**] I haven't read the relevant standards, but I suspect it's not a linear
range but a N-dimensional non-Euclidian space.
