It seems like you would want to do normal compression with a very low
threshold (about the noise level) and a negative ratio.

then you end up with a curve like

\
/ \
/ \

Then you can add that into your original signal, to get something
approximating "upward compression".

Also, perhaps the expander from tap-plugins might do what you want:

ok, thats what i want

perhaps my math is to weak...lol

I simply will try it out.

just giving more info: amateur-singer, half an hour of time, lives long
from here. we recorded her voice, but in the lower parts she sang very
quiet, so with normal compression i would compress 95% of what is
correct only to add more gain to those parts. so i thought about this
option instead. probably i should simply elevate volume in those part
instead.
