 yes, this object is quite usefull, in fact I meant that I need to set  up
the amplitude modulation for getting a correct db value with the slider,
over a logaritmic scale, then the slider setting and the test signal average amplitude
should have almost the same value.

yes certainly, for the moment I've found

[slider value between 0 and 1]--- [rmstodb]--[- 100]  to fit almost log scale,
 but the need is for having 0db at  height * 4 / 6,  something like that
