So you want amplitude 'a' dependant quantization size 'q' ? take your
chosen q(a); in your example it seems you want a simple line:
define f(a) as integral of 1/q from a=0 to a; also calculate the
inverse of f(a) i.e. a(f);
now for each sample do: out=a(round(f(in))) where round is any floor
or the like...
in your example: q=q0-k*a with for example q(0)=0.001 and
