You have to give -1 dB before using the +2 dB
shelving (again, two
knobs). I know the math... I was just asking if there exist a tilt eq!
If not, no problem :) I go with shelving.
The only difference using a cascade of 2 shelving in place of a gain
stage + 1 shelving is in the phase response of the system. So in the
90% of the use case there will be no difference between this two
approaches but, again, that's not my original question.
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
^^^^^^^^^^^^^^
Not good worded. You don't need to move the graph, the graphs are
equal, just the "start" frequency is different to the "centre"
frequency, but the result is the same. You could name it an x-axis or
y-axis move, resp. just a move of the selected frequency. De facto you
are using a shelving filter, even if you chose a tilt filter. The level
of the audio signal changes what ever approach you chose.
It's not what you were asking for, but it should be mentioned for the
record.
