English isn't my native language.

It doesn't matter. If you use a tilt EQ you chose a centre frequency,
if you use a shelving filter, you chose a start frequency, but if you
move the graph, they are the same. If you manipulate the frequencies
you automatically manipulate the amplitude/level of the signal, it
makes no difference what approach you chose. Changing the level of the
frequencies requires to adjust the level of the audio signal.
